CrossChat

Privacy Policy

Last updated: 5 July 2026

CrossChat is a browser extension that replaces YouTube’s live chat with the corresponding Twitch channel’s chat, rendering Twitch, 7TV, BTTV and FFZ emotes.

Summary

CrossChat has no backend server and no analytics. It does not collect, transmit, sell, or share any of your personal data. Everything the extension stores stays in your browser, on your own machine.

What CrossChat stores locally

The extension keeps the following in chrome.storage.local on your device:

• Settings and preferences — your panel and theme configuration.
• Channel mappings — which Twitch channel corresponds to each YouTube channel, so it works automatically the next time you visit.
• Twitch access token — only if you choose to log in with Twitch to send messages. This token is stored so you do not have to log in again on every visit.

This data never leaves your machine and is never sent to the developer or any third party.

Network connections

To function, the extension communicates directly from your browser with the following services. These connections send only what is needed to read and render chat, and are never used for tracking:

• Twitch — to read chat, resolve the channel, and (only after you log in) send messages on your behalf.
• 7TV, BetterTTV, FrankerFaceZ — to fetch emote sets and load emote and badge images.

CrossChat does not add tracking, telemetry, or advertising to any of these requests.

Authentication

Logging in with Twitch is optional and only needed to send messages. It uses Twitch’s official OAuth flow via chrome.identity. The resulting access token is stored locally and used solely to send messages through Twitch’s API. If you only read chat, you never log in and no token is stored.

Data collection

CrossChat does not collect any user data as defined by the Chrome Web Store, meaning it does not transmit any data off your device to the developer or third parties. Specifically, it does not collect personally identifiable information, authentication credentials, personal communications, location, browsing history, or user activity.

Removing your data

Uninstalling the extension removes everything it stored in your browser. You can also clear it at any time from your browser’s extension storage settings.

Changes to this policy

If this policy changes, the updated version will be published in this repository with a new date above.
