Crumbless privacy policy
Last updated: 26 October 2026
Crumbless does not collect, sell or share any personal data, and it has no server.
What the extension reads
To decide which cookies to delete, Crumbless looks at the addresses of your open tabs and at the cookies stored in your browser. This happens on your computer only. It never reads the content of the pages you visit and never injects scripts into them.
What is saved
Your keep lists, your settings and a short activity log (dates, numbers of cookies removed and site names) are stored in your browser's extension storage on your computer. You can clear the log at any time from the settings page.
What is sent
Nothing. Crumbless has no analytics, no tracking and makes no network requests of its own.
