Privacy Policy
Effective October 27, 2026
This policy covers the Predict2Win website (predict2win.app), the Predict2Win Android app and the Odds Converter & Notes Sync Chrome extension, which share one account. Questions go to support@predict2win.app.
What we collect
- Your account. If you sign in with Google: your name, email address, profile photo and Google account ID. If you sign in with email: your email address, the name you enter and your password, which Firebase Authentication (Google) stores for us; we never see it.
- Your member record. Your name, email and photo, when you first and last used Predict2Win, whether you joined on the website or in the extension, and when you confirmed you're 18 or older.
- What you save. Your game notes, picks and wagers, archived games, the odds and prices shown on your dashboard, and your settings, including the SportsLine and Action Network experts, Telegram channels, 𝕏 accounts and Splash players you follow. Only your account can read this.
- What cappers and commenters post. A capper's profile name, bio, picks, analysis and results are shown to everyone who's signed in. A comment shows your name and its text to signed-in users. A capper can see which accounts follow them.
- On your device. The website and the Android app keep your sign-in session and settings in the browser's local storage; the extension keeps its data in Chrome's storage. Signing out removes the session from that device.
- Pages the extension reads. On Kalshi, Novig, 4codds, 4cx, DraftKings, SportsLine, Action Network, PropBomb, 𝕏 and Discord, the extension reads the page you have open to convert odds, show your notes and pick up picks and prices. What it finds stays in your browser and, when you're signed in, syncs to your account. It doesn't run on other sites.
We don't use advertising, analytics or tracking tools, and we don't collect payment details, your location or your contacts.
How we use it
- To sign you in and keep your notes, picks and settings in sync across the website, the app and the extension.
- To match picks to games, show prices and grade results.
- To send account emails: address verification and password resets.
- To keep Predict2Win for adults and to turn on Premium and Capper features for invited accounts. The operator can see the member list (name, email, photo and dates) to manage access.
Who else handles it
- Google Firebase (Authentication, Realtime Database, Hosting and Cloud Functions) stores and processes your data for us, in the United States.
- Public data services. To fetch scores, prices and the picks you follow, the website, the extension or our server contact ESPN, FxTwitter (public 𝕏 posts), Splash Sports, Telegram's public channel pages, Kalshi, Novig, Polymarket, ProphetX and 4cx. Those requests carry the team, contest, channel or account names being looked up, and requests from your device carry your IP address; they don't include your account details.
- Google Fonts serves this site's fonts, so your browser sends it your IP address.
- Links out. Kalshi, Novig, 4cx, sportsbooks, Telegram and 𝕏 have their own privacy policies once you open them.
We don't sell your data or share it for advertising. We'd disclose it only if the law requires us to.
Keeping and deleting your data
We keep your data while your account exists. You can delete notes and picks yourself at any time, and the dashboard's Export button downloads your saved bets as CSV or JSON.
To delete your account and everything stored with it, email support@predict2win.app from the address you sign in with. We delete it within 30 days and reply when it's done. Uninstalling the app or the extension removes what it kept on that device.
You can also email us to get a copy of your data or to correct it.
Security
Everything travels over HTTPS, and the database only lets each account read and write its own private data. No system is perfectly secure, so use a strong password if you sign in with email.
Adults only
Predict2Win is for adults 18 and older (21 and older where your state requires it). We don't knowingly collect data from anyone younger, and we delete an account if we learn it belongs to a minor.
Changes
If this policy changes, we'll update the date at the top of this page, and we'll say so on the site when a change affects what we collect or share.
