Mask sensitive information in AI chats, web forms, support pages, and everyday family use before you send. Everything runs locally in your browser.
Safe Privacy Mask is a free Chrome extension that finds and replaces sensitive information directly inside AI chats, web forms, support pages, and other registered input fields.
Your text is masked locally in your browser before you send it. The extension does not upload your original text or detection results to an external server.

Names, addresses, school names, and other custom terms
Custom patterns created with regular expressions
You can create your own replacement rules—for example:
Taylor Smith → [Name]
Home address → [Address]
School name → [School]
Internal project name → [Project]
Safe Privacy Mask can be configured for a family member’s browser with custom rules for names, addresses, phone numbers, school names, and other details they may accidentally include in a message or form.
It does not monitor browsing activity or decide what someone may send. It simply replaces matching information in the input field and leaves the final decision to the person using the browser.
Detection and masking run on your device
No account required
No advertising
No analytics or telemetry inside the extension
No automatic submission
Settings and custom rules stay in Chrome’s local storage
Safe Privacy Mask detects text using recognizable formats and the rules you configure. It may miss information or identify something incorrectly, so always review the masked text before sending it.
Mask what you do not need to share—wherever you type it.
