About OddsGuard9
What OddsGuard is, who it's for, and how we make money.
What is OddsGuard?
What is OddsGuard?
OddsGuard is a free real-time sports odds comparison service. Whenever you view a market on a supported sportsbook, OddsGuard shows you the same selection's price across our feed of 75+ price comparison sources so you can weigh prices and promotions side-by-side before you bet. We do not take bets — we only compare prices.
How does OddsGuard work?
How does OddsGuard work?
When you land on a supported sportsbook, OddsGuard reads the odds already visible on the page and cross-checks them against our live feed from other sportsbooks. If a better price exists elsewhere, you see it right on the page via an inline overlay next to the original odds. The extension doesn't log in to your sportsbook account, touch your balance, or place bets.
Who is OddsGuard built for?
Who is OddsGuard built for?
Anyone who bets on sports and doesn't want to manually open six tabs to compare prices. Casual bettors use it to see at a glance where the same selection is priced differently (for example a +125 moneyline at one book vs. +110 at another). More experienced bettors use the comparison, filtering, and best-price tools to weigh lines across books. OddsGuard is an information tool — outcomes still depend on the bets you place and are not guaranteed.
Is OddsGuard free to use?
Is OddsGuard free to use?
Yes. The browser extension, the Safari app for iPhone / iPad / Mac, and the embeddable widget are free. Core odds comparison, bookmaker recommendations, basic notifications, and price data from our 75+ sources are all included at no cost.
How does OddsGuard make money if it's free?
How does OddsGuard make money if it's free?
OddsGuard earns affiliate commissions when users open a new account at a sportsbook through one of our referral links. We never charge you, and the payout you see from a sportsbook is not affected by whether you come through our link.
Is OddsGuard a sportsbook?
Is OddsGuard a sportsbook?
No. OddsGuard does not accept wagers, hold funds, or settle bets. We're a comparison and discovery tool — the actual bets are placed on the sportsbook of your choice, on that sportsbook's site, under that sportsbook's terms.
Do I need to be 18 or 21 to use OddsGuard?
Do I need to be 18 or 21 to use OddsGuard?
Yes. When you first install the extension or open the mobile app, you must confirm that you meet the minimum legal gambling age in your jurisdiction (18 in most regions, 21 in many US states). Viewing sports betting odds is age-restricted in many countries.
Which countries is OddsGuard available in?
Which countries is OddsGuard available in?
OddsGuard is available worldwide. The specific sportsbooks we surface depend on your location — we only show books that actually take bets where you are. If a sportsbook is geo-blocked in your country, it won't appear in your comparisons.
Which browsers and devices are supported?
Which browsers and devices are supported?
OddsGuard ships as: (1) a browser extension for Chrome, Brave, Edge, and other Chromium browsers, (2) a Firefox add-on, (3) a Safari extension via our iOS app (iPhone / iPad) and our macOS app, and (4) a Windows desktop app for users who want it to run alongside any browser. An embeddable widget is also available for website owners.
Browser Extension14
Chrome, Firefox, Edge, Brave — install, use, update, uninstall.
How do I install the OddsGuard extension?
How do I install the OddsGuard extension?
Firefox users: install from Firefox Add-ons (addons.mozilla.org) by searching for "OddsGuard". Chrome / Brave / Edge users: install from the Chrome Web Store, or download our Windows desktop app which bundles the extension. Safari users on iPhone, iPad, or Mac: install the OddsGuard app from the App Store and enable the OddsGuard extension in Safari settings.
What does the toolbar icon do?
What does the toolbar icon do?
Click the OddsGuard icon in your browser's toolbar to open the popup — that's where you'll find your notifications, a quick-links list of supported sportsbooks, account controls, and settings. Better-price indicators for individual selections appear as an inline overlay on the sportsbook page itself, right next to the odds.
How does the on-page overlay work?
How does the on-page overlay work?
When you view a betting market on a supported sportsbook, OddsGuard injects a small comparison element next to or near the odds. It shows the best price currently in our comparison for the same selection across connected books, the difference vs. the page you're on, and a quick link to open that book. Odds can move between the moment we compare and the moment you place a bet — always confirm the price on the sportsbook's bet slip. You can hide or toggle the overlay from the extension's Options page.
Are there keyboard shortcuts?
Are there keyboard shortcuts?
Yes. Ctrl+Shift+B (Command+Shift+B on macOS) opens the OddsGuard popup. Alt+Shift+O toggles the on-page comparison overlay. You can customize or disable these in your browser's extension shortcuts page (e.g. chrome://extensions/shortcuts).
How do I update the extension?
How do I update the extension?
OddsGuard updates automatically through your browser's extension store — no action required. To force-check for updates: Chrome / Edge / Brave → go to chrome://extensions, enable "Developer mode", and click "Update". Firefox → about:addons, then click the gear icon and "Check for Updates". We'll also show an in-app notice when a critical update ships.
What permissions does the extension need and why?
What permissions does the extension need and why?
OddsGuard requests storage (to remember settings and sign-in), tabs and activeTab (to know when you're on a supported site), content-script injection (to draw the on-page overlay), webNavigation (to detect page changes on single-page sportsbook apps), alarms (for scheduled polling), and notifications (for alerts). On Chrome, Brave, and Edge, site access is scoped to the exact sportsbook domains we support. On Firefox and Safari, platform rules require a broader "all websites" permission — but OddsGuard still only activates on the same supported sportsbook domains. We do NOT collect browsing outside those sites.
Can I use OddsGuard on a phone browser?
Can I use OddsGuard on a phone browser?
On iPhone and iPad, yes — via the OddsGuard Safari app (see the iOS & Mac section). On Android, browser extensions for Chrome are limited; we recommend Firefox for Android, which supports our add-on. A dedicated Android app is on our roadmap.
Does it work with multiple browser profiles?
Does it work with multiple browser profiles?
Yes. Install the extension in each Chrome / Firefox / Edge profile you use. Your preferences will sync across profiles if you sign in to your OddsGuard account in each one.
Where are the full settings? The toolbar popup is small.
Where are the full settings? The toolbar popup is small.
The toolbar popup has the most common toggles (sign-in, price format, theme, special offers, notification history). The full Options page has everything else: price overlay on/off, bonus notifications, the "Jump straight to the odds" toggle, multi-selection currency, location / region override, and the "Replay onboarding tour" button. Open it from: the popup's Quick Actions → Extension Settings, or by right-clicking the toolbar icon → Options, or in your browser via chrome://extensions → OddsGuard → Details → Extension options.
What is "Jump straight to the odds"?
What is "Jump straight to the odds"?
A toggle in the extension popup and Options page. When a sportsbook uses a two-step flow — promo landing page first, then the specific event page — this setting controls whether we automatically forward you through to the event once the landing page has loaded, or whether we stop at the landing page so you can choose. It's on by default so affiliate attribution works correctly and you reach the line you were shopping. Turn it off if you'd prefer to land on promo pages and navigate yourself.
What is the round floating button on sportsbook pages?
What is the round floating button on sportsbook pages?
The floating action button (FAB) is an in-page quick-access menu that appears on supported sportsbook pages. Tap it to open Bonuses (current promos in your region), the Parlay Bet Slip (multi-selection tool), Help & Support, Responsible Gaming links, Rate OddsGuard, Share OddsGuard, or replay the onboarding tour. You can hide the FAB entirely from the extension's Options page if you prefer the toolbar icon only.
Can I change how OddsGuard looks? What are the unlockable themes?
Can I change how OddsGuard looks? What are the unlockable themes?
Yes. Open the extension popup → Theme section to switch between the default themes for free. A small set of premium themes can be unlocked through a one-time upgrade or a Premium subscription (shown as "Unlock" in the Theme section), or by redeeming a code sent by our team. Unlocked themes are tied to your installation; sign in to sync them across devices. The same controls live in the Windows desktop app and the iOS / macOS app's More → Appearance tab.
How do the parlay bet slip and "Multi-Selection Currency" setting work?
How do the parlay bet slip and "Multi-Selection Currency" setting work?
The on-page Parlay Bet Slip (opened from the FAB or toolbar) lets you add selections as you browse, see the combined odds, and evaluate which book gives the best total price across the legs. Note: sportsbook-specific same-game-parlay prices are bespoke to each book and aren't broadly comparable — the parlay slip is best for cross-event parlays. The "Multi-Selection Currency" setting in the extension's Options page tells OddsGuard which currency to display stake / return figures in when you use the slip.
How do I uninstall the extension?
How do I uninstall the extension?
Chrome / Brave / Edge: open chrome://extensions, find OddsGuard, click "Remove". Firefox: about:addons, click the OddsGuard entry, then "Remove". Safari (iOS/iPadOS): Settings → Safari → Extensions → OddsGuard → toggle off, or delete the app to remove completely. You'll be offered an optional exit survey — your feedback genuinely shapes the roadmap.
OddsGuard for iPhone, iPad & Mac9
Safari extension plus a native app for browsing odds on the go.
What is the OddsGuard app for Apple devices?
What is the OddsGuard app for Apple devices?
It's a native iOS / iPadOS / macOS app that does two things: (1) it ships a Safari Web Extension — the same comparison overlay you get on desktop — that enables odds comparison whenever you browse a supported sportsbook in Safari; and (2) it includes a built-in odds browser so you can shop lines directly inside the app, even when you're not actively on a sportsbook website.
What are the four tabs in the iPhone / iPad app?
What are the four tabs in the iPhone / iPad app?
(1) Activate — walks you through turning on the Safari extension and shows its current status; (2) Odds — browse live prices by sport, league, and event and tap a price to jump to the relevant sportsbook; (3) Bonuses — current sportsbook promotions, filtered by All / Sports / Casino, with a regional section so you only see offers available where you are; (4) More — your account, appearance / themes, help & support, responsible gambling links, legal pages, and the list of supported sportsbooks.
How does the Bonuses tab work?
How does the Bonuses tab work?
The Bonuses tab lists current sportsbook promotional offers. Filter by All / Sports / Casino. You'll see an "In your region" section (what's legally available where you are) and an "Other regions" section for context. Each bonus links out to the sportsbook; offers are subject to each operator's terms, eligibility, and wagering requirements (18+ or 21+ depending on your jurisdiction). Pull down to refresh. If the extension can't be detected on older iOS versions, the tab still works in stand-alone mode.
How do I set it up on iPhone or iPad?
How do I set it up on iPhone or iPad?
Install the OddsGuard app from the App Store. Open it once — you'll be walked through: (1) opening Settings → Safari → Extensions → OddsGuard, (2) toggling the extension ON, (3) granting "All Websites" permission so it can activate on any supported sportsbook, and (4) visiting a sportsbook in Safari to see the floating OddsGuard button. The app's home screen has a shortcut that opens the right Settings page directly.
How do I set it up on Mac?
How do I set it up on Mac?
Install the OddsGuard Mac app from the Mac App Store. Open Safari → Settings → Extensions and enable OddsGuard. Grant site permissions ("Always Allow on Every Website" is recommended — we only activate on supported sportsbook domains regardless). The overlay and toolbar icon work just like on Windows Chrome / Firefox.
Why does the app ask for "All Websites" permission?
Why does the app ask for "All Websites" permission?
Safari's permission model only offers per-site or all-sites granting. OddsGuard only activates on the specific sportsbook domains we support — even with "All Websites" granted, we don't read data from other websites. The broad permission is a Safari platform requirement, not a scope expansion on our side.
Can I browse odds inside the app without visiting a sportsbook?
Can I browse odds inside the app without visiting a sportsbook?
Yes. The app has an Odds tab where you can pick a sport, league, and event and see live prices from every supported book side-by-side. Tapping a price opens the relevant sportsbook via its app (if installed) or a web view.
Is there an iOS Home Screen widget?
Is there an iOS Home Screen widget?
A Home Screen widget is on the roadmap. Today, you can add the app icon or a Siri Shortcut that opens straight into the Odds tab for your favorite sport.
Is there an Android version?
Is there an Android version?
Not yet as a dedicated native app. Firefox for Android supports our add-on, which gives you the core overlay experience. A native Android app is on the roadmap.
Windows Desktop App6
A standalone wrapper for users who prefer not to install an extension.
What is OddsGuard Desktop for Windows?
What is OddsGuard Desktop for Windows?
A lightweight Windows application that gives you the full OddsGuard experience without having to install a browser extension. It's ideal if you switch browsers often or can't install extensions on a managed / work machine that still allows desktop software.
Should I use the desktop app or the browser extension?
Should I use the desktop app or the browser extension?
Either works — they deliver the same odds comparison. The browser extension is a lighter install and auto-updates with your browser. The desktop app is useful when you use multiple browsers, can't install extensions on your machine, or want a dedicated window. You do not need both.
How do I get started with the Windows desktop app?
How do I get started with the Windows desktop app?
On first launch you'll see a short welcome flow (age check, terms, optional marketing). The app then has three tabs: Connection (connect the app to Chrome so it sees the page you're on, pick a preferred sportsbook, and "Open in Chrome" for that book), Notifications (same notification center as the extension), and Settings (display options, overlay, min-savings threshold, region, themes, Startup options such as "Launch on Windows startup" and "Auto-connect to Chrome"). You can close the app to the tray and right-click the tray icon to Pause / Resume without quitting.
Why does Windows show a SmartScreen warning when I run the installer?
Why does Windows show a SmartScreen warning when I run the installer?
OddsGuard Desktop is currently in early access while our Microsoft Authenticode code-signing certificate finishes reputation-building. Windows flags new installers until they've been downloaded and run enough times for the certificate to be fully recognized. If you wish to continue, click "More info" then "Run anyway". Full instructions are on our Install page; the warning will disappear once the certificate is established.
What are the system requirements?
What are the system requirements?
Windows 10 or later (64-bit), around 150 MB of disk space, and an active internet connection. It runs unobtrusively in the background and uses minimal CPU and RAM when idle.
Is there a Mac or Linux desktop version?
Is there a Mac or Linux desktop version?
Mac users should use the native OddsGuard Safari app (see the iOS & Mac section) — it covers the desktop use case on macOS. A Linux build is not currently planned; Linux users can install the Chromium or Firefox extension.
Free Embeddable Widget7
Add a live odds comparison widget to your own website or blog.
What is the free odds widget?
What is the free odds widget?
A drop-in embeddable widget that displays live odds comparison across our 75+ price sources directly on your own website. It's designed for sports bloggers, tipsters, content sites, and affiliates who want real-time pricing next to their articles.
How do I embed the widget on my site?
How do I embed the widget on my site?
Two options: (1) Iframe — copy a single <iframe> tag with your API key and affiliate ID. (2) JavaScript — add one <script> tag and a <div> with data attributes for finer control (auto-sizing, theming). Full copy-paste snippets and a live customizer are on the Widgets page.
Do I need an API key?
Do I need an API key?
No — the widget works without one. If you'd like per-site tracking, origin validation, and higher rate limits, you can create a free API key from your OddsGuard account under Account Settings → API Keys and pass it to the widget. Without a key, the widget still loads and shows live odds under the default public rate limits.
Can I customize the widget to match my site?
Can I customize the widget to match my site?
Yes. You can pick from our preset themes (Light, Light Blue, Warm, Earth, Dark, Navy, Emerald, Crimson), or pass your own hex colors for background, text, accent, border, odds cells, and active item highlights. You can also choose layout (standard with sidebar vs. slim for mobile), set a default sport / league, and — for the JavaScript embed — pass data-height and data-width attributes to control how it sizes inside your page.
Can I earn commissions from widget clicks?
Can I earn commissions from widget clicks?
Yes. Pass your affiliateId parameter and every outbound click to a sportsbook from your widget is attributed to you. Apply for the affiliate program at affiliate@oddsguard.com to get your unique ID. Widget-only integrations are welcome — no content minimums.
Will the widget slow down my site?
Will the widget slow down my site?
The widget is designed to minimise impact: it loads asynchronously and lazy-hydrates so it won't block your page's Core Web Vitals, and the iframe embed variant is fully sandboxed. The odds data itself is served from our cached API so repeat visits are fast.
Are there usage restrictions?
Are there usage restrictions?
The widget is free for legitimate use on a website you own or operate. You may not wrap the widget output and re-serve the data through your own API, scrape widget responses, or embed in a way that misrepresents the source of the odds. Full terms apply on sign-up.
Supported Sportsbooks6
Which sportsbook sites we compare, in which regions, and why.
Which sportsbooks does OddsGuard compare?
Which sportsbooks does OddsGuard compare?
Two answers, because the two numbers are different:
- Extension overlay: The browser / Safari extension’s on-page overlay activates on 39 specific sportsbook sites today — those are the pages where OddsGuard reads the odds you’re looking at and injects a comparison right next to them. See the full list with logos in Supported Sportsbooks.
- Price comparison feed: The prices we compare those odds against come from a broader feed of 75+ sources, including major US books (DraftKings, FanDuel, BetMGM, Caesars, BetRivers, theScore Bet, Bovada, BetOnline), UK / European books (Bet365, William Hill, Betfair, Paddy Power, Ladbrokes, Coral, Sky Bet, Betfred, BoyleSports, Unibet, 888sport, LeoVegas, Casumo, Betsson, BetVictor, Betway, Grosvenor, and more), and exchanges / sharp books (Pinnacle, Smarkets, Novig, ProphetX, Kalshi). See the full list with logos in Comparison Sources.
Wondering which books are available where you live? See the Odds by Country directory in the footer.
What's the difference between "extension-integrated" and other books?
What's the difference between "extension-integrated" and other books?
Extension-integrated sportsbooks are those where OddsGuard runs the on-page overlay (reads odds from the page, places the comparison element next to them). Other books in our coverage are shown inside our popup and in-app odds browser — you'll see their prices when shopping lines, but there's no overlay when you visit their site. Both types feed the same comparison engine.
How do I request a sportsbook that isn't covered?
How do I request a sportsbook that isn't covered?
Email support@oddsguard.com with the site's name and URL. Adding a new sportsbook involves reverse-engineering its page layout and maintaining an adapter as the site evolves, so we prioritize requests based on user demand, regional availability, and how stable the site's structure is.
Does the list of books depend on where I am?
Does the list of books depend on where I am?
Yes — we only show sportsbooks legally available in your jurisdiction. If you're in New Jersey, you'll see US-licensed books; if you're in the UK, you'll see UKGC-licensed books. Your location is detected automatically from your IP, but you can manually override the region in Settings if we get it wrong.
Do I need to log in to a sportsbook for OddsGuard to work?
Do I need to log in to a sportsbook for OddsGuard to work?
No. OddsGuard only reads odds that are already visible on the page — the same odds you can see as a logged-out visitor. We never access your account, balance, or bet history.
Do you support betting exchanges?
Do you support betting exchanges?
Yes. We support Betfair Exchange, Smarkets, Novig, ProphetX, and Kalshi. For exchange prices we show the best available back price; exchange commission is noted where relevant.
Sports & Markets Coverage5
Leagues, bet types, and markets we compare.
Which sports and leagues are covered?
Which sports and leagues are covered?
OddsGuard covers the major sports worldwide: American Football (NFL, NCAAF, CFL, UFL), Basketball (NBA, NCAAB, WNBA, Euroleague), Soccer (EPL, La Liga, Bundesliga, Serie A, Ligue 1, Champions League, MLS, and 100+ other leagues), Baseball (MLB, NCAAB, NPB, KBO), Ice Hockey (NHL, SHL, KHL), Tennis (ATP, WTA, Grand Slams), Cricket (IPL, Test, T20, ODI), Golf (Masters, PGA, European Tour, LIV), MMA, Boxing, Rugby League & Union, Aussie Rules, Lacrosse, Darts, Snooker, Cycling, and more. The exact leagues active each day are shown in the app.
What bet types (markets) are compared?
What bet types (markets) are compared?
Moneyline / match winner, point spreads / handicaps, totals (over / under), draw no bet, both teams to score, double chance, correct score, and futures / outrights (championship winner, MVP, division winner). Player props and alternate lines are supported on most major US books and expanding; coverage varies by sport and book.
Do you show live (in-play) odds?
Do you show live (in-play) odds?
Yes for the majority of supported books. Live prices update more frequently and can diverge quickly between books, which is where OddsGuard is often most useful. The overlay automatically follows live-market changes.
Do you compare same-game parlays (SGPs)?
Do you compare same-game parlays (SGPs)?
SGP pricing is proprietary to each sportsbook and not broadly comparable across books in a like-for-like way. OddsGuard compares the individual leg prices that typically go into SGPs so you can see where each leg is priced best; we don't currently compute a composite SGP price.
Are season-long futures and outrights covered?
Are season-long futures and outrights covered?
Yes. Championship winner, division / conference winner, season awards (MVP, Rookie of the Year), and tournament outrights are included where books publish them. Futures prices move less often but the gaps between books are often the largest.
Odds Data & Display7
Where the odds come from, how often they update, and how to read them.
Where do your odds come from?
Where do your odds come from?
Two sources, combined: (1) on-page reading — for sportsbooks where we run an adapter, we read the exact odds displayed in your browser; (2) our live feed — a continuously-updated price service that polls every supported book. The feed powers the comparison, the in-app odds browser, the widget, and pages like the website's Odds section.
How often do odds update?
How often do odds update?
On a supported sportsbook, overlays update the moment the page's odds change. In the app's odds browser and widget, live / in-play markets refresh on the order of seconds, while pre-match and deep-menu markets (e.g. futures / outrights) refresh on the order of minutes. There is no manual refresh needed.
Can I change the odds format (American, Decimal, or Fractional)?
Can I change the odds format (American, Decimal, or Fractional)?
Yes. Open the extension popup (or the app) → Settings → Price Format, and choose American, Decimal, or Fractional, or "Same as Page" to match whatever the sportsbook is using. The choice applies everywhere: overlays, popup, in-app odds, and widget.
How accurate are the comparisons?
How accurate are the comparisons?
We aim for accurate comparisons and reject stale prices aggressively, but odds can shift in the fraction of a second between our fetch and your screen — especially for live markets. Always confirm the final price on the sportsbook's own bet slip before you commit. If you spot a consistent discrepancy, please report it so we can fix our adapter.
What do "Positive EV" and "value" labels mean?
What do "Positive EV" and "value" labels mean?
Positive EV (expected value) is a mathematical concept: a price looks favourable when compared to an estimated "fair" probability derived from sharp-book consensus. It's an informational label, not a prediction or a recommendation to bet. Individual bets can still lose, short-term variance is large, and long-run results are never guaranteed. If a bet is flagged "positive EV" it does not mean it will win — it means the price is statistically interesting relative to the model. Please bet responsibly and only stake what you can afford to lose.
What is arbitrage in sports betting?
What is arbitrage in sports betting?
Arbitrage refers to situations where opposite outcomes of the same market are priced highly enough across different books that the combined stakes could, in theory, lock in a small mathematical edge. In practice, arbitrage carries material risks: sportsbooks can void bets under palpable-error rules, maximum-stake limits may prevent you from placing a full position, rules between books differ (push / overtime / void policies), and prices move fast — by the time both legs are placed, the edge can be gone or reversed. OddsGuard does not currently provide user-facing arbitrage alerts — this explainer is educational only, and no outcome is guaranteed.
What is line movement and why does it matter?
What is line movement and why does it matter?
"Line movement" describes how a price or point-spread changes over time at a sportsbook — for example a spread moving from -3 to -3.5. Big moves often reflect injuries, team news, weather, or heavy one-sided betting. Tracking movement is useful context for understanding how the market has evolved, but past movement does not predict future movement or outcomes. OddsGuard does not currently publish user-facing line-history charts.
Account, Sign-In & Sync6
Creating an account, signing in, syncing across devices.
Do I need an account to use OddsGuard?
Do I need an account to use OddsGuard?
No. The extension, mobile app, and widget all work anonymously. Signed-in accounts sync eligible preferences (like your selected theme) across devices and keep a longer notification history.
How do I sign in?
How do I sign in?
Click the OddsGuard toolbar icon → "Sign In". You'll be sent to our website to authenticate with your email and password. Once done, the extension links to your account automatically. On mobile, the sign-in flow is in the More tab of the app.
I forgot my password — how do I reset it?
I forgot my password — how do I reset it?
On the sign-in page click "Forgot password" and enter your email. We'll send a reset link valid for 1 hour. If it doesn't arrive, check spam and verify you're using the same email you signed up with.
Can I use OddsGuard on multiple devices?
Can I use OddsGuard on multiple devices?
Yes. Sign in with the same account on each device (browser extension, iPhone, iPad, Mac, Windows desktop). Preferences (odds format, region, notification settings, favorite sports) sync automatically. Each installation still has its own anonymous installation ID for technical reasons but they're all linked to your account.
How do I sign out?
How do I sign out?
Open the extension popup (or app), tap your profile, and choose "Sign Out". The device returns to anonymous mode. Your account data stays intact on our servers and will resync when you sign in again.
How do I delete my account?
How do I delete my account?
Sign in at our website → Account Settings → Data & Privacy → Delete Account. This removes your profile, saved preferences, and notification history. Some records may be retained temporarily for legal compliance (see Privacy section below). You can also request deletion without ever signing in — see the "Can I request deletion of my data?" question.
Notifications & Alerts6
What you get notified about, how to tune it, and how to silence it.
What types of notifications will I receive?
What types of notifications will I receive?
OddsGuard groups notifications into system messages (critical updates, required actions — always on), price alerts (when we see a better price at another book for a market you're on or have flagged), and opt-in "Special offer" notifications (marketing — promos, new sportsbooks, product launches). Special offer notifications are off by default and can be toggled any time.
What are "Special offer" notifications?
What are "Special offer" notifications?
Optional marketing alerts about sportsbook promotional offers (e.g. bonus bets, deposit boosts), new sportsbooks we've added, and product launches. Each offer is subject to the issuing sportsbook's terms, eligibility, and — where applicable — wagering requirements; 18+ or 21+ depending on your jurisdiction. Special offer notifications are off by default and fully separate from system notifications. Toggle them in the extension popup under Notification Preferences.
How do I opt in or out of marketing notifications?
How do I opt in or out of marketing notifications?
On first install, you can choose whether to enable Special offer notifications (unchecked by default). At any time, open the extension popup → Settings → Notification Preferences → toggle "Special offer notifications". System notifications cannot be disabled — they cover critical updates and security.
How long is my notification history kept?
How long is my notification history kept?
Guest (not signed in): 7 days rolling. Signed-in: 1 year. Signed-in users can scroll back through past price alerts and system notices for reference.
How do I view my notification history?
How do I view my notification history?
Click the OddsGuard toolbar icon → Notifications tab. Each entry shows delivery status (seen / unseen), type, and the related sportsbook / market where applicable.
Do I need to grant browser notification permission?
Do I need to grant browser notification permission?
Yes for native OS-level pop-ups. Your browser will prompt you on first use. If you declined earlier, open your browser's site permissions and allow notifications from the extension, or from our website for web-push alerts.
Privacy, Data & Security9
What we collect, how it's used, and your data-rights controls.
What data does OddsGuard collect?
What data does OddsGuard collect?
We collect only what's needed to provide the service: an anonymous installation UUID, browser type and version, OS and device type, country and state/region (for relevant odds), your preferences, usage events on supported sportsbook sites, affiliate click tracking, notification delivery status, and — if you sign in — the email address on your account. We do not collect your general browsing, and we never sell personal data. Full detail is in our Privacy Policy.
Does OddsGuard track all of my browsing?
Does OddsGuard track all of my browsing?
No. The extension is only active on supported sportsbook domains. On every other site you visit, OddsGuard does nothing — no scripts run, no data is sent. You can verify this in your browser's Network tab.
What is my Installation ID and where do I find it?
What is my Installation ID and where do I find it?
Your Installation ID (also shown as "App ID") is a random UUID assigned to your extension install at first launch. It identifies your installation to our servers without identifying you personally. Find it: open the extension popup → scroll to the footer → "ID: xxxxxxxx..." — click to copy the full ID. On mobile: Settings tab → About → Installation ID.
What data is collected during installation?
What data is collected during installation?
At install time: your anonymous Installation UUID, browser type and version, OS, your country and state/region (from IP, for showing relevant prices), and your consent choices (age confirmation, marketing opt-in). Nothing about your identity, and no browsing history.

Yes. Transport is HTTPS-only (TLS 1.2+). Sensitive data is encrypted at rest. Passwords are hashed using modern algorithms. We never store credentials for any sportsbook — OddsGuard only observes the odds data visible on the page and never touches your sportsbook login.
Do you sell my data?
Do you sell my data?
No. We do not sell, rent, or share personal data with third parties for their marketing purposes. Our revenue comes from sportsbook affiliate commissions when users open a new account through our links. Full detail in the Privacy Policy.

How is the age requirement enforced?
How is the age requirement enforced?
On first install we ask you to confirm you meet the minimum legal gambling age in your jurisdiction (18 in most regions, 21 in many US states). If you decline, the extension stays in a disabled state. You must be over the legal age in your region to use OddsGuard.

Can I pause or stop seeing odds in OddsGuard?
Can I pause or stop seeing odds in OddsGuard?
Yes, and the controls differ by platform. Windows Desktop: right-click the OddsGuard tray icon → "Pause" (resumes when you click "Resume" or restart the app). Browser extension: turn the extension off from your browser's extensions page (chrome://extensions or about:addons), or uninstall it — this instantly stops overlays and notifications. iOS / macOS Safari: Settings → Safari → Extensions → OddsGuard → toggle off. For a more lasting break, uninstall the apps and extensions, and consider contacting GAMSTOP (UK) or your national self-exclusion scheme so the sportsbooks themselves block your account.
Does OddsGuard set deposit or betting limits?
Does OddsGuard set deposit or betting limits?
No — OddsGuard is a price-comparison tool and doesn't take bets or hold funds. Deposit limits, loss limits, and session-time limits are set inside your sportsbook account directly. Every licensed sportsbook we link to supports player-set limits by regulation.
Troubleshooting8
Fixes for the things that occasionally go wrong.
The overlay isn't showing any price comparisons
The overlay isn't showing any price comparisons
Common causes: (1) you're on a sportsbook page we don't cover yet — check the coverage list; (2) the market or sport isn't supported for that book yet; (3) your region restricts the books we'd compare to; (4) the sportsbook recently redesigned their page and our adapter is catching up. Quick fixes: hard-refresh the page (Ctrl+F5), disable and re-enable the extension, sign out and back in, or check our status page for known incidents.
The toolbar icon is missing
The toolbar icon is missing
Chrome / Brave / Edge: click the puzzle icon in the toolbar, find OddsGuard, and click the pin to show it permanently. Firefox: right-click the toolbar → Customize → drag the OddsGuard icon into place. If the extension isn't listed, verify it's installed and enabled at chrome://extensions or about:addons.
I'm not receiving notifications
I'm not receiving notifications
Three places to check: (1) extension popup → Settings → Notification Preferences — make sure the category you expect is toggled on. (2) Your browser's site permissions — allow notifications from the extension. (3) Your operating system — on Windows/macOS, make sure notifications aren't globally muted or in Focus / Do Not Disturb mode.
My location is detected incorrectly
My location is detected incorrectly
OddsGuard uses IP-based geolocation. If you're behind a VPN, corporate proxy, or travelling, detection can be off. You can override the detected region from the extension options page (Settings → Region). If that doesn't resolve it, email support@oddsguard.com with your expected country or state and we'll help correct it.
The extension shows "disabled" or won't activate
The extension shows "disabled" or won't activate
This usually means privacy consent or age confirmation was declined during first-run. To re-enable, uninstall the extension, then reinstall — the onboarding will show again, and accepting the required notices will activate it. If it still reports disabled, email support@oddsguard.com with your Installation ID.
The extension seems to slow down my browser
The extension seems to slow down my browser
OddsGuard is idle on non-sportsbook sites and designed to be lightweight on supported ones. If you notice lag: (1) update to the latest version, (2) disable other sportsbook / odds extensions that might be racing ours, (3) temporarily disable OddsGuard to confirm it's the cause. If confirmed, please send us the sportsbook URL — we'll investigate.

Please tell us: open the popup → Report an issue, or email support@oddsguard.com with the sportsbook, sport / event, market, expected price, and the price OddsGuard showed. Screenshots help enormously. We'll cross-check against our feed and patch the adapter if needed.
