DataBlur

DataBlur is a browser extension designed for professionals who need to protect sensitive information during live screen sharing and recordings. It allows users to blur confidential data on their screens with a single click, ensuring that private details are not exposed during calls, demos, presentations, or when creating tutorials and videos. The extension processes all data locally within the browser, with no information sent to the cloud, providing instant privacy without requiring any setup.

Key features include one-click blurring of text, specific elements, or custom areas, as well as the ability to auto-detect and mask common personally identifiable information such as emails, IDs, phone numbers, passwords, and API keys. DataBlur also supports persistent rules per domain, so users can keep recurring sections hidden across sessions, making it suitable for repeated use in professional contexts. The tool is compatible with popular browsers, including Google Chrome, Microsoft Edge, Brave, Comet, and Mozilla Firefox, and is designed to work across widely used web applications like Google Docs, Meet, Notion Web, and Gmail. Its lightweight architecture is optimized for performance and does not rely on AI or cloud inference.

DataBlur is positioned for roles such as sales engineers, freelance consultants, financial and legal advisors, content creators, and other professionals who regularly share their screens and need to comply with privacy or confidentiality requirements. DataBlur distinguishes itself by offering 100% local processing, ensuring that sensitive data remains on the user's device at all times.

As a browser extension focused on privacy during screen sharing and recording, DataBlur addresses the need for real-time masking of confidential information without post-production editing. Its domain-specific rules and auto-detection of sensitive data make it a practical solution for maintaining privacy in professional digital workflows.
