Privacy Policy for Turn Sync

Last updated: August 2026

This privacy policy describes how the Turn Sync app ("the app", "we") handles your data. Turn Sync is a shared board game clock: one player hosts a game room, other players join with a short room code, and everyone sees the same turn timer. We only handle the minimum data needed to make that work.

1. Developer and contact

2. What data is processed?

2.1 Display name

When you join a game room you type a display name (for example a first name or a nickname). This name:

• Is chosen freely by you — no real name, email address or phone number is required
• Is visible to the other players in the same room, so everyone can see whose turn it is
• Is stored on our backend only for as long as the game room exists (see section 5)

2.2 Anonymous user ID

The app signs in anonymously to our backend (Supabase). This creates a random, technical user ID on your device. The ID:

• Contains no personal information and cannot be traced back to you by us
• Is used only to authorize game actions (for example, that only the host can pause the game) and to let you rejoin a room after restarting the app

2.3 Game data

While a game is running, the app stores game state on our backend: room code, turn order, time limits, and per-turn timing (how long each turn took, whether the time limit was exceeded). This is what makes the shared clock and the game statistics work. Game data is linked to your display name within the room, not to any real-world identity.

3. Purpose of processing

We process data exclusively to:

• Keep all players' clocks in sync in real time
• Show whose turn it is and enforce the game rules the host has chosen
• Show turn statistics (average time, total time, overtime count) during and after the game

We do not use the data for advertising, profiling, or analytics.

4. Sharing and selling of data

We do not sell or share your personal data. Your display name and game statistics are visible only to the other players in the same game room. Our backend is hosted by Supabase on servers in the EU; Supabase acts as our data processor and does not use the data for its own purposes.

5. Storage and deletion

• Game rooms (including display names and turn statistics) are deleted automatically 24 hours after they are created.
• Leaving a room removes you from the game immediately.
• Local settings (sound and vibration preferences, last joined room) are stored only on your device and are removed when you uninstall the app.

There are no user accounts and no long-term storage of personal data.

6. Security

All network traffic between the app and our backend is encrypted (HTTPS/TLS). Access to game data is restricted so that only members of a game room can read that room's data, and all game actions are authorized server-side.

7. Your rights (GDPR)

You have the right to:

• Access – know what we process (described in full in section 2)
• Erasure – leave a room to be removed from it immediately; all room data is deleted automatically within 24 hours regardless
• Complain – to the Norwegian Data Protection Authority (Datatilsynet) if you believe our processing violates data protection law

8. Children

The app requires no account and collects no contact information. Display names are free-text; we recommend using a nickname. The app is intended for general audiences playing board games together.

9. Advertising and tracking

Turn Sync contains no advertising and does not track users across apps or websites.

10. Changes

We may update this privacy policy. Material changes will be reflected in the "Last updated" date at the top of this page.
