Last updated: 9 November 2026. This page explains what WatchParty collects, what it is used for and how long it is kept. We keep only what the service needs to work.
What we store
Google sign-in: the display name, email and avatar Google provides. We never receive your Google password.
Sign-in with a name (guest): only the name you type. Guest accounts are deleted after 3 days.
Rooms: room name, video link, room settings and creator. Rooms created by guests are deleted once nobody is in them.
Short-lived technical logs (IP address, time of access) to fight abuse and fix bugs.
Feedback and bug reports you send, with technical details (browser, page, error) so we can fix problems.
What we do not store
Chat messages: they are delivered to the people in the room and not kept.
Picture and sound of screen sharing and voice: they go directly between devices, or through a relay server when two networks cannot connect directly, and are never recorded.
Films watched with the WatchParty Sync extension: it only reads the playback position to keep everyone in step.
Cookies and browser storage
We use one sign-in cookie (not readable by page scripts) and store a few of your choices in the browser, such as language and light or dark theme. No advertising or tracking cookies.
Third parties
Google: sign-in.
YouTube: YouTube videos play in YouTube's player under Google's policies.
TMDB: movie information in Movie Night (this product uses the TMDB API but is not endorsed or certified by TMDB).
Infrastructure: Vercel (website), a virtual server in Singapore (application server and connection relay), Supabase (database).
Your rights
You can ask to see or delete your account data at any time through the Feedback button in the app. Room hosts can delete their own rooms.
Changes
When this policy changes, the date at the top of the page changes too.
