Privacy Policy

Battleship · Developer and operator: Sudarev Daniil · Last updated: October 28, 2026

Battleship (“the app”) is a free game without ads or purchases. It can be played without an account, and then no personal data is collected. If you choose to sign in, we keep the minimum data described below, only to run that feature. We never sell or share your data.

1. No account

The app works without sign-up, including games against bots and with friends. We do not ask for your name, email or phone number.

2. Optional account

You can sign in with Apple or Google — only if you want to keep your score when you change phones. Then our server (Supabase, protected by access rules) stores: your email address and sign-in ID, your nickname and emoji avatar, a friend code, your language and country code (taken from your phone’s region settings, not from location), and your win/loss score against the bots. The account is shared by Sudarev games, so the same nickname appears in all of them.

This data is not used for advertising or tracking and is not shared with third parties. You can delete the account and all this data in the app: “Account” → “Delete account”. Deletion is immediate and permanent and removes the cloud data of all Sudarev games; the game on your phone keeps working.

How to delete your account without the app: email [email protected] from the address you signed in with (or tell us your nickname and friend code), subject “Delete account”. We delete the account, nickname and score within 7 days and confirm by email. Nothing is kept.

3. Playing with friends

In “Play with friends” you join a room by code, QR code or over the same Wi‑Fi network. Other players at the table see the name you type in and your moves. Over the internet, moves and names are relayed in real time through our server (Supabase Realtime) over an encrypted connection and are not stored. Over Wi‑Fi, phones talk to each other directly. There is no chat.

4. Rules questions

If you ask a question with the “Ask” button, only the question text and the game name are sent to our server — no name or account. If there is no ready answer, the question is passed to an AI service, and the answer is saved without any link to you to help the next players.

5. Data on your device

Your settings (number of players, game variant, bot level, theme) and your score against the bots are stored only on your phone. They are not sent to us unless you sign in. Deleting the app deletes this data.

6. No ads, analytics or tracking

Games against bots work offline. The app has no advertising, analytics, crash reporting, trackers, in-app purchases or third-party SDKs that collect data, and does not use the advertising ID.

7. Permissions

The camera is used only to scan a room’s QR code, and only when you open the scanner yourself: the picture is processed on the phone, is not stored and is not sent anywhere. Network and Wi‑Fi access are used only to play with friends. The microphone, contacts, photos and location are not used.

8. Children

Without an account the app collects no data from anyone. Accounts are intended for users aged 13 and over.

9. Changes and contact

If this policy changes, the new version will be published on this page. Contact: [email protected].
