👋 The short version
CousinsWatch PRO connects you and one other person for a private video call. Your audio, video, and screen share travel directly between your two browsers — they never touch our servers. The only thing that passes through an external service is the room code used to start the call, and that disappears once the session ends.
📡 What data is used and where it goes
| Data | Purpose | Where it goes | How long |
|---|---|---|---|
| Room code (e.g. CW-ABC123) |
Lets you and your cousin find each other and establish a connection | Temporarily written to your own Firebase Realtime Database — a service you set up and control | Deleted at end of session |
| Audio & video | The call itself | Travels directly between the two browsers (peer-to-peer), encrypted via WebRTC DTLS-SRTP | Never stored |
| Screen share | Sharing your screen during a call | Same direct peer-to-peer WebRTC stream | Never stored |
| IP address | NAT traversal — helping the two browsers find each other across the internet | Shared transiently with STUN servers (Google) and a TURN relay (OpenRelay / Metered) only if a direct connection cannot be made. Not logged or stored by us. | Not retained |
🔐 Encryption
All audio, video, and screen content is encrypted end-to-end using WebRTC's built-in DTLS-SRTP protocol. This is the same encryption standard used by video-calling apps like Google Meet and Zoom.
🗄️ Firebase — your own database
CousinsWatch PRO uses a Firebase Realtime Database to exchange the small connection messages needed to start a call (this is called "signaling"). Crucially, you provide your own Firebase project — we do not operate a shared server. You are in full control of that database and can apply security rules to restrict who can read or write to it.
No call content — audio, video, or screen — ever touches Firebase. Only the room code and WebRTC negotiation metadata (a few hundred bytes) pass through it, and only for the duration needed to establish the connection.
🍪 Cookies and tracking
The extension uses no cookies, no analytics, no crash reporting services, and no advertising SDKs of any kind. There is no account system and no sign-up.
👶 Children's privacy
CousinsWatch PRO does not knowingly collect any information from anyone. Because no data is collected at all, there is no differentiated treatment based on age.
🔄 Changes to this policy
If we make material changes to this policy, we will update the effective date above and publish a note in the extension's changelog. Continued use of the extension after a change constitutes acceptance of the updated policy.
