What PII Masker does

PII Masker helps you remove personal data (names, e-mail addresses, phone numbers, IBANs and similar) from text before you send it to AI chat services, e-mail or web forms. It consists of a desktop app and a browser extension.

Text you type

• The browser extension reads the text of input fields on web pages you visit, only to find personal data in it.
• That text is sent only to the PII Masker desktop app running on your own computer (address 127.0.0.1). It is never sent to us or to any other server.
• The original values that were replaced by tags such as [NAME_1] are kept in your browser's session memory, so that AI answers can be shown with the real values. They are deleted when the browser is closed, and you can clear them at any time in the extension's popup.
• We do not sell, share or use this data for advertising, profiling or model training.

License server (pii.xoperr.dev)

To check your license and to download the detection model, the desktop app contacts this server. It receives and stores only:

• the license you were invited to (the name the license was issued to and its expiry date);
• a device identifier and public key generated by the app, the device name and operating system you activate on;
• the IP address and time of activation and of license checks, and the times the model was downloaded.

This information is used only to issue, check and revoke licenses and to protect the model from unauthorised copying. It is kept while the license is active and deleted within 90 days after it ends. Each downloaded copy of the model carries an invisible identifier of the license it was issued to.

Your rights

You can ask for a copy of the license data about you, its correction or its deletion (which ends the license) through the person or organisation that invited you, or by e-mail: hinhab1@gmail.com.
