DeleteActivity is a browser extension designed to help users clean their Facebook history safely and privately. It allows bulk deletion of posts, comments, likes, and Messenger messages without requiring a password or uploading data to the cloud. The tool runs 100% locally in your browser, utilizing your active Facebook session. Users can filter activities by date range, content type, or keywords to target specific items for removal. It features built-in smart rate limiting to mimic human behavior and prevent account flagging. Additionally, users can export deleted activity logs as CSV or JSON for record-keeping.
