DeleteActivity is a privacy-focused Chrome and Edge extension for cleaning up Facebook Activity Log history. It can batch-delete supported posts and comments, remove likes and reactions, and unsend eligible Messenger messages. Users work inside their existing Facebook browser session, choose content types, filter by date or keywords, inspect matches, and run paced cleanup tasks. Deleted-activity records can be exported as CSV or JSON. No Facebook password or cloud upload of activity content is needed, and a limited free plan is available.
