Privacy Policy

Belot Online · version 1.3.1 · last updated: 3 September 2026

SR HR BS EN

This policy explains what data the Belot Online app collects, what it is used for, and the choices you have. It is written from what the app actually does, rather than from a template of things that might apply.

1. Data we collect

Account. An account is required to play. You register with an email address and password, or with a Google account. Sign-in is handled by Firebase Authentication — we never see or store your password. We store your email address and whether it has been verified.

Profile and statistics. Alongside your account we store: the username you choose, your selected avatar, level and experience points, ELO rating, wins and losses, win streak, coins and diamonds, achievements earned and tournaments won.

Publicly visible: your username, avatar, ELO and win/loss record appear on public leaderboards and to other players in the lobby, in rooms and during a match. The leaderboards are readable by anyone. Please do not put personal information in your username.

Gameplay. While the app is open, other players can see that you are online. During a match, the table state, the cards dealt and the moves played are stored temporarily. When a match ends we keep a record of it: the participants' usernames and the final score.

Notifications. If you allow notifications we store a device token (Firebase Cloud Messaging) and use it only to tell you 10 minutes before a tournament you entered begins, and two minutes before your own match starts. We do not send marketing messages.

Purchases. Buying diamonds exists on Android only, through Google Play Billing. Payment is handled by Google — we never see your card details. We keep a record of the transaction (its identifier, the package bought, your account) so that the same purchase cannot be charged or credited twice. The iOS version has no purchases at all; there, diamonds are earned through play and can be exchanged for coins.

Advertising. The app shows ads through Google AdMob. AdMob itself collects data from your device — advertising identifier, IP address and approximate country-level location, device model and OS version, and ad interactions. That data is collected by Google under its own policy and is not stored by us.

Analytics. Firebase Analytics records which screens you open and basic game events — when a room is created, when a match starts and ends, when a rewarded ad is watched and when a purchase completes. We use this in aggregate, to see what works in the game and what does not.

Feedback. If you send us a rating or a comment from inside the app, we store the text you wrote.

Temporary — crash diagnostics. Until 22 September 2026 the app records technical details about errors: the message and stack trace, the screen it happened on, the room identifier, the app version, the platform and a session identifier, linked to your account. It exists solely to find the cause of crashes and will be switched off and deleted on that date.

2. Why we use this data

To let you sign in and keep your progress across devices and sessions.
To match you with other players and show opponents who you are (name, avatar, rating).
To run the leaderboards, tournaments and achievements.
To tell you when a tournament and your own match begin — only if you allowed it.
To credit purchased diamonds and prevent double charging.
To show advertising, which is what funds the free game.
To find and fix errors and crashes.

We do not sell your data and do not pass it to third parties for marketing.

3. Third-party services

We use the following services. Each processes data under its own privacy policy:

Service	Provider	Purpose	Policy
Firebase (Auth, Firestore, Realtime Database, Functions, Hosting)	Google LLC	Accounts, database, server logic	View
Google Sign-In	Google LLC	Signing in with a Google account	View
Google AdMob	Google LLC	Serving advertising	View
Firebase Analytics	Google LLC	Usage analytics	View
Firebase Cloud Messaging	Google LLC	Push notifications	View
Google Play Billing	Google LLC	Buying diamonds (Android only)	View

4. Our other apps

Belot Online is linked to our apps Jamb and Memory: when you reach level five, you automatically receive diamonds in those too. They are separate projects with separate accounts, so your account is matched across them by email address — that is the only thing compared for this purpose. If you are not registered in the other app with the same email, nothing is transferred and nothing is created.

5. Advertising and your choices

The app is free and funded by advertising. Three kinds are shown:

Banners — a strip at the bottom of the screen, in the lobby, in the market and on the match results screen.
Interstitial (full-screen) — these appear on their own, at the end of a match, before the results screen, in both ordinary and tournament matches. They are never shown during play and never interrupt a match in progress.
Rewarded — you start these entirely yourself and always get something in return: in the lobby for extra coins, in a room when you lack the coins to enter, and after a defeat to recover half the ELO points lost.

Consent to personalised ads. If you are in the European Economic Area, the United Kingdom or Switzerland, a consent form (Google User Messaging Platform) is shown before the first ad. If you decline, ads are still shown — but non-personalised ones, selected without your advertising identifier. You can change your choice at any time under Settings → Advertising.

Separately, your device offers its own controls:

Android: Settings → Google → Ads — turn off ads personalisation or reset your advertising identifier.
iOS: we ask for tracking permission (App Tracking Transparency). If you decline, only non-personalised ads are shown. You can change this in Settings → Privacy & Security → Tracking.

Turning off personalisation limits ad targeting but does not remove ads from the app.

6. Retention and deletion

We keep your data for as long as your account exists. Data about a match in progress is removed when the match ends. Diagnostic records are deleted automatically, and in any case by 22 September 2026.

Deleting your account, in the app. You can delete your account yourself at any time: open Profile, press Delete account and confirm. It takes effect immediately and removes:

your account and email address,
your username, avatar, level, ELO rating and statistics,
your entry on the public leaderboards,
coins, diamonds and achievements earned,
tournament entries and the messages that go with them,
ratings and comments you sent, and diagnostic records.

Deletion is permanent and cannot be undone; purchased diamonds are not refunded in money. The record of a purchase itself is kept with its link to your account removed — it exists solely so the same purchase cannot be charged twice, and holds no personal data.

If for any reason you cannot get into the app, write to b0sd3v@gmail.com from the address you registered with and we will delete the account within 30 days, backups included.

7. Children

The app is not intended for children under 13 and we do not knowingly collect their data. If we learn that we have received data from a child under 13 without parental consent, we will delete it. If you believe this has happened, please contact us.

8. Changes to this policy

We may change this policy when the way the app works changes, or when regulations require it. We publish material changes on this page with a new update date. Continuing to use the app after a change means you accept it.
