Safe Privacy Mask — Keep personal information out of AI chats

Description

Masks emails, phones and API keys in the input box before you hit send. No copy-paste to another site. On device, no account. Safe Privacy Mask is a free Chrome extension that masks personal information in AI chat input fields before you send your message. Use it for work, everyday questions, or to help family members and loved ones use AI more thoughtfully. It helps you avoid accidentally sharing email addresses, phone numbers, API keys, and similar information, so you can review the masked text before sending. 【For your family and the people you care about】 When someone asks AI to polish an email or help with a problem, their message may include personal contact details. You can help a family member or loved one get started, set up masking rules together, and build a habit of checking what they share. 【Useful at work, too】 • Email summaries and editing: mask email addresses and phone numbers before asking AI for help. • Customer support summaries and translations: add custom rules to replace customer names and project names. • Code and log troubleshooting: help catch strings that look like API keys or tokens before sharing them with AI. 【Start small, right in your browser】 Free to use, with no account required. You can start masking personal information in everyday text without signing up for a paid service. Works with major AI chat services, including ChatGPT, Claude, and Gemini. Mask text directly in the input field you are using, without moving it to a separate masking website. 【Make it work for you】 • Add custom rules for names and other text, with support for regular expressions. • Register additional websites and input fields. • Choose when masking takes place. Masking applies to supported services and registered input fields. It does not work on every webpage or in every input field. 【Detection and masking stay in your browser】 The extension does not send your text or detection results to external servers for detection or masking. It contains no ads or analytics and does not collect your browsing history. Settings are stored locally using Chrome’s storage. Access to supported or registered pages is used to detect and replace text in input fields. 【Before you use it】 Detection relies on text patterns and the rules you configure. Names and similar information need custom rules. The extension may miss sensitive information or mask text unnecessarily, so always review the result before sending. It does not guarantee complete anonymization. The extension does not prevent the website or AI service you are using from collecting or transmitting text entered on its pages. Follow your organization’s policies when using it at work. It is not a replacement for organization-wide data protection measures. Changes to websites or AI services may affect how the extension works. 【Support】 Report a problem or share a suggestion: https://legacy-tools.dev/support
