Your secrets stay on your Mac.
Policeman sits between your AI tools and the model APIs. Before a request leaves, it removes API keys, card numbers, IBANs and passwords, and it stops dangerous commands an AI asks to run.
API keys and tokens, values from your .env files, card numbers, IBANs and passwords are replaced before the request is sent.
Email addresses and phone numbers are flagged. Set them to Remove or Stop in one click.
An AI asking to run rm -rf, read a key file or open a remote shell is stopped before anything runs.
Instructions hidden in a page or a file the AI is about to read are flagged or withheld.
Every check runs locally. Policeman has no account, no cloud and no tracking, and it sends nothing to BRIMIND.
If the guard stops, your traffic goes direct. Other websites pass through untouched and are never read.
