Subscribed Since is a browser extension designed for users who want to see the exact date and duration of their YouTube channel subscriptions. It displays a small badge next to YouTube’s subscribe button on channel pages, indicating both the precise subscription date and the tenure, formatted as years, months, or days depending on how long the user has been subscribed. The badge appears across all types of YouTube channel URLs, including @handles, /channel/, /c/, and /user/ formats, and supports both current and older header layouts on YouTube.
The extension is available for Chromium-based browsers and Firefox. After installation, users sign in with their Google account, at which point the extension fetches their list of subscriptions a single time and securely caches this data in the browser’s local extension storage. Subscription data is refreshed automatically every six hours, and also updates shortly after subscribing or unsubscribing to a channel. Users can manually refresh their subscription data through the extension’s pop-up menu. The extension operates with read-only access to YouTube, ensuring it cannot modify subscriptions or make changes to the user’s account.
Subscribed Since emphasizes privacy by storing all subscription data locally on the user's device, with no data sent to external servers, no analytics, and no custom backend. Users can sign out at any time to clear the local cache and revoke access. The extension requires minimal permissions and is not affiliated with YouTube or Google. Currently, it is available in English, with plans for additional language support in the future. Subscribed Since is open source, allowing users to review the code and contribute via GitHub.
