Privacy Policy for tandem.watch

Last Updated: February 2026

Overview

tandem.watch is a Chrome extension that enables synchronized Netflix watching with peer-to-peer video and audio chat. This privacy policy explains what data we collect and how we handle it.

Data We Collect

1. Real-Time Playback Activity

• What: Netflix playback events (play, pause, seek, current timestamp)
• Why: To synchronize playback across all viewers in a watch party
• Where: Transmitted via WebSocket to our signaling server, then relayed to other participants
• Retention: Not stored persistently; discarded when the watch party ends

2. Peer-to-Peer Video and Audio

• What: Live video stream from your webcam and audio from your microphone
• Why: To enable face-to-face communication during watch parties
• How: Streamed directly peer-to-peer using WebRTC with DTLS-SRTP encryption
• Storage: Never transmitted to or stored on our central servers—data goes directly between participants only

3. Room Identification

• What: Room ID used to join a watch party
• Why: To organize viewers into separate watch parties and prevent unauthorized access
• Retention: Maintained only while the room is active

Data We Do NOT Collect

• Personal information (name, email, address, etc.)
• Your Netflix account credentials
• Your IP address or location
• Browsing history outside of Netflix
• Payment or financial information
• Health or biometric data

How Your Data is Protected

1. P2P Encryption: Video and audio streams use DTLS-SRTP encryption end-to-end
2. No Central Storage: Media streams never touch our servers—they go directly between peers
3. Minimal Server Data: Our signaling server only stores temporary metadata (room IDs, connection states)
4. Browser Sandbox: The extension runs within Chrome's security sandbox

Third-Party Services

Our signaling server may use STUN/TURN services to help establish peer connections:

• STUN: Used to discover your public IP for direct connections
• TURN: Used only as a fallback if a direct connection cannot be established
• These services do not log your data

Data Sharing

We do not sell, transfer, or share your data with third parties. Data is only shared:

• Between peers in your watch party (directly via P2P)
• With our signaling server (temporarily, for connection management)
• Where required by law (if legally compelled)

Your Controls

• Camera/Microphone: You grant permission when prompted; you can revoke permissions in Chrome settings
• Room Participation: You control who joins your watch party by sharing the room ID
• Extension Removal: Uninstall the extension anytime to stop all data collection

For Chrome Web Store: This extension does not use personal data for advertising, marketing, or any purpose unrelated to synchronized watching.
