DeleteActivity

DeleteActivity is a browser extension that helps you remove large amounts of Facebook activity from your account without sending data to external servers. It works in your browser using your active Facebook session, so you don’t need to enter your password into a third-party service.

You can target what to remove by filtering date ranges, content types (posts, comments, likes, Messenger messages) or keywords. The extension includes smart rate limiting to imitate normal user actions and reduce the chance of triggering account flags.

Deleted activity can be exported for your records. The makers provide CSV and JSON exports.

• Runs locally in the browser, no cloud uploads
• Filters by date, type and keyword
• Smart rate limiting to mimic human behaviour
• Export deleted activity as CSV or JSON
