Plain-language policy

Privacy stays in the browser.

Effective August 27, 2026

Tab Sunset List is a local-first browser extension. We designed it so its core job does not require a server or an account.

What the extension stores

The extension stores the URLs and titles of tabs you deliberately tag, your optional rationale, expiry dates, saved outcomes, and the most recently closed item for undo. This data is held in your browser’s local extension storage.

What leaves your device

Nothing from the extension is transmitted to us. There is no analytics SDK, advertising identifier, cloud sync, or browsing-history endpoint. Bookmark actions use your browser’s built-in bookmark API.

Permissions

Deleting your data

Removing the extension clears its local extension storage according to your browser’s behavior. Bookmarks you explicitly created remain under your control and can be removed in the browser’s bookmark manager.

This website

This static website uses no cookies, tracking pixels, analytics, third-party fonts, or third-party runtime scripts. Its service worker caches public site files on your device so the policy remains available offline.

Contact and changes

Issues can be filed in the project’s public source repository. If this policy changes, its effective date and repository history will show the change.
