1. What this extension does

GChat Custom Notifications is a Chrome browser extension that plays a custom sound when a new incoming message is detected on chat.google.com. It does not interact with Google Chat's servers, read message content for any external purpose, or communicate with any backend service.

No personal information (name, email, account ID)
No message content or metadata
No browsing history or activity
No usage analytics or telemetry
No crash reports sent to external servers

3. Data stored locally on your device

The extension stores the following data exclusively in your browser's local storage using the Chrome Storage API. This data never leaves your device.

Data	Storage	Purpose
Sound source preference (built-in / upload / YouTube)	chrome.storage.sync	Remember your chosen notification type
Volume level, cooldown, debug mode	chrome.storage.sync	Preserve your settings across sessions
YouTube URL and clip timestamps	chrome.storage.sync	Remember which clip to play
Uploaded audio file (base64)	chrome.storage.local	Store your custom sound file locally

chrome.storage.sync data may be synced across your Chrome devices if you are signed into Chrome sync. This sync is managed entirely by Google and is subject to Google's Privacy Policy.

4. Permissions used

Permission	Why it is needed

5. Third-party services

If you choose the YouTube clip sound source, the extension loads a YouTube embed in a hidden browser context. This request is made from your browser directly to YouTube (Google). YouTube may log this request according to their own privacy policy. The extension does not control or intercept this traffic.

No other third-party service, SDK, or analytics library is included in this extension.
