Catfish Catcher for LinkedIn collects no data and sends nothing anywhere.

What it reads. LinkedIn pages you open, and the profiles of flagged post authors outside your network. Reading happens in your browser only.

What it stores, in your browser only:
- your settings,
- profile check results, for 7 days,
- short fingerprints of post text, for 30 days, to spot copied posts.

What it sends. Nothing. There are no servers, analytics or ads. The two optional links (LinkedIn search and Google Lens) open in a new tab only when you click them.

Removing data. Uninstalling the extension deletes everything it stored.
