Sync Watch is a browser extension that enables synchronized video watching with friends. This privacy policy explains what information is collected and how it is used.
When you use Sync Watch, the following information is transmitted to our synchronization server:
- Room codes: Randomly generated 6-character codes used to identify watch sessions
- Playback state: Video play/pause status, current timestamp, and playback speed
- Chat messages: Text messages sent through the in-extension chat feature (if used)
We do NOT collect, store, or have access to:
- Personal information (name, email, address)
- Account credentials for streaming services
- Video content or streams
- Browsing history outside of active watch sessions
- Payment information
The transmitted data is used solely to:
- Synchronize video playback between participants in the same room
- Deliver chat messages to room participants
- Room codes and playback state: Stored only in memory during active sessions; deleted when all participants leave
- Chat messages: Not stored; relayed in real-time and discarded
- Local storage: Room connection state is stored locally in your browser to maintain your session
The extension connects to our WebSocket server hosted on Railway.app for real-time synchronization. No data is shared with other third parties.
All WebSocket connections use secure WSS (WebSocket Secure) protocol for encrypted transmission.
Since we don't store personal data, there is no personal information to access, modify, or delete. You can clear local extension data through your browser settings.
We may update this privacy policy from time to time. Changes will be reflected in the "Last Updated" date.
