Twitch Sync Player Privacy Policy

Chrome extension ยท Last updated 6 October 2026

In brief

Twitch Sync Player does not collect, store on any server, sell or share any personal data. It has no analytics, no tracking and no account. The only things it remembers are your chosen delay and volume, and they stay inside your own browser.

What the extension does

It plays a Twitch live stream with a delay you choose, so the streamer's commentary can be lined up with a match you are watching on another screen.

Data stored on your device

The extension saves two settings in your browser's local storage:

These settings never leave your computer. The developer cannot see them. Removing the extension deletes them.

Data sent over the network

To play a stream, the extension contacts Twitch directly from your browser, at gql.twitch.tv and *.ttvnw.net. It sends the name of the channel you chose and nothing about you: requests are made without your Twitch cookies or account.

As with any website you open, Twitch can see your IP address and standard browser information when the stream is loaded. How Twitch handles that is described in Twitch's own privacy notice.

The extension contacts no other server. Nothing is sent to the developer.

Permissions

Third parties

No data is sold, transferred or shared with third parties. The extension is not affiliated with or endorsed by Twitch Interactive, Inc.

Changes and contact

If this policy changes, the new version will be published on this page with a new date. For questions, use the Support section of the extension's page on the Chrome Web Store.
