Why Syncync asks for each permission

Last updated: June 19, 2026

Plain-language draft. Syncync is an independently operated service. We've written this to match what the app actually does. It is not legal advice and should be reviewed by a lawyer before launch.

The Syncync extension asks for the smallest set of permissions it needs to sync playback and run the room call. Here's every one, in plain English.

Single purpose

Syncync has one purpose: let a small group watch the same Netflix or YouTube video in sync, with a video call and chat on top. Every permission below serves that purpose and nothing else.

Site access

  • Access to www.netflix.com and www.youtube.com

    So the extension can read the player’s time position and play/pause state on the page you’re watching and keep everyone in the room on the same frame. It reads playback status only — never the video itself.

Browser permissions

  • storage

    To briefly hold your room join token while a tab opens. Cleared when your browser session ends.

  • tabs / activeTab

    To open the watch tab for your room and know which tab the room is running in.

  • scripting

    To run the small sync script on the Netflix/YouTube page that reads and sets the player position.

  • clipboardWrite

    To copy your room invite link to the clipboard when you click “Copy link”.

  • contentSettings

    To make sure the page is allowed to autoplay so playback can start in sync for everyone.

Camera & microphone

The room video call needs your camera and microphone. These are requested by your browser (not as an extension permission) the first time you join a call, and the streams stay peer-to-peer — they're never recorded or sent to our servers. You can turn your camera or mic off any time.

What it never does

Syncync never captures, records, or stores video content, never reads cookies from Netflix or YouTube, and never accesses pages other than the supported watch sites and its own backend. Questions about any permission? Email [email protected].
