ChatBridge — Privacy Policy

Last updated: 2026-09-20

ChatBridge is a personal, self-hosted tool that merges live chat from Twitch and YouTube into one overlay for a streamer’s own broadcast. It runs entirely on the streamer’s own computer. There is no hosted service, no server operated by anyone else, and no accounts other than the streamer’s own. What it accesses

With the streamer’s explicit OAuth consent, ChatBridge uses:

YouTube Data API (youtube.force-ssl scope) to read the live chat of the streamer's own broadcasts and to post messages to that chat on the streamer's behalf.
Twitch API / EventSub to read the streamer's own channel chat and to post messages to it on the streamer's behalf.

What it stores

OAuth tokens for the connected accounts, saved in a local folder (.tokens/) on the streamer's computer so the login does not have to be repeated. They are never sent anywhere except to Twitch and Google to make the API calls above.
A short in-memory history of recent chat messages, used to render the overlay. It is discarded when the program stops. Nothing is written to a database or sent to any third party.

What it does not do

It does not collect, sell, share, or analyse any personal data.
It does not track viewers, build profiles, or use analytics of any kind.
It does not transmit chat content anywhere other than the platform it came from, or — when the streamer turns the relay feature on — to the streamer's own chat on the other platform, visibly prefixed with its origin.

Google API Services User Data Policy

ChatBridge’s use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. Revoking access

Access can be revoked at any time from Google account permissions and Twitch connections, and by deleting the local .tokens/ folder. Contact
