Subscribed Since - YouTube Subscriptions 제작자: Isaac Ibidun

Subscribed Since adds a clean badge directly to YouTube channel pages, showing:
- your exact subscription date
- how long you've been subscribed

The extension works automatically once you sign in with your Google account and authorize read-only YouTube access.

How it works
1. Sign in with Google from the extension pop-up
2. The extension securely reads your YouTube subscriptions using the official YouTube Data API
3. Subscription data is stored locally in your browser
4. Visit any subscribed YouTube channel to see when you subscribed
