# Built for anyone handling sensitive information.

A clinic, a law firm, a trading desk and a codebase each hold different secrets. Once pasted into an AI tool and sent, none can be taken back. Each page shows what Locke looks for.

- ## Healthcare

  Keep PHI out of the prompt. Locke flags MRNs, diagnosis codes and patient names before it's sent.

- ## Legal

  Research and draft with AI while Locke flags case numbers, client names and privilege markers.

  Learn more
- ## Financial Services

  Use AI for analysis without sending account numbers, card numbers or wallet addresses.

  Learn more
- ## Technology

  Mask API keys, tokens and connection strings before they reach a coding assistant or chatbot.

  Learn more
- ## Individuals

  Keep your SSN, card numbers and medical details out of everyday AI chats.
