The short version

filmkorner keeps a film in sync between friends and gives them a room to chat and talk. We keep only what that needs, delete rooms a day after they go quiet, and never sell data or show ads. We count page visits and a few steps like “a friend joined” with Vercel's cookieless analytics, which can't identify you, and there are no tracking cookies.

What we keep

  • Your display name, the one you type in, shown to people in your room.
  • Chat messages and reactions you send in a room, with the point in the film they were sent at.
  • What the room is watching: the title's name and id on the streaming service, whether it's playing, and how far in.
  • A sign-in. Guests get an anonymous one with no personal details. If you save an account we keep your email address, and if you use Google we receive your email, name and profile picture from Google.
  • Your profile and friends, if you have an account and set them up: the handle and name you pick, who your friends are, requests you've sent or received, and room invites. Other people see only your handle and name, never your email, and only your friends can invite you to a room.
  • Your plan: whether your account has Pro. filmkorner doesn't take payments; if that changes, this page will say who handles them first.
  • Anonymous voice statistics: whether a call connected directly or through a relay, and how long it took. These contain nothing about you or your room.

Voice

Calls go directly between the people in a room, encrypted, and are never recorded. Like any direct call, the people you talk to can see your IP address. When a direct connection isn't possible, the call passes through a relay server, which forwards the encrypted audio without being able to listen to it.

The browser extension

The filmkorner extension for Chrome keeps your streaming tab in step with your room. On Netflix, YouTube, Prime Video, Disney+ and HBO Max pages it reads only the player: whether it's playing, the position, the title's name and id, and whether an ad is showing (and how long it has left), which your room sees so it can wait for you. It presses play, pause and seek when your room does, and shows the room's chat over the film.

It does not read your browsing history, other websites, or anything else on those pages, and it never sees your streaming account or password. It stores your current room session (room code, your display name and a sign-in token) in the extension's own storage, and talks only to filmkorner and our database.

How long we keep it

  • Rooms, with their chat, reactions and what they were watching, are deleted 24 hours after the last activity. A Pro room given a permanent link is kept while its owner has Pro.
  • Accounts, with their profile, friends and plan, are kept until they're deleted.
  • Room invites are deleted after 12 hours.
  • Your name and preferences in the browser stay on your device until you clear them.

Who else is involved

We use a few services to run filmkorner, only for that purpose:

  • Supabase hosts our database, sign-in and the live connection rooms run on.
  • Vercel serves the website.
  • Sentry receives error reports from the website and the extension: what broke and where, never your chat, voice, room or account.
  • Google, if you choose to sign in with it.
  • A voice relay provider, for calls that can't connect directly.
  • YouTube, only if you press play on a video in one of our blog posts. Nothing loads from YouTube before that.

We don't sell or share your data with anyone else.

Your choices

You can use filmkorner as a guest without giving us any personal details. Removing the extension from Chrome deletes everything it stored.

filmkorner isn't meant for children under 13, and we don't knowingly collect their data.

Changes

If this policy changes, we'll update it here and change the date at the top.
