The Keyblind browser extension does not collect, store, transmit, or share any user data of any kind.
All detection and interception happens entirely within your browser. The extension scans page content locally to detect API key patterns and intercepts paste events — all processing happens on-device and the results are never sent anywhere.
User preferences (enable/disable toggles) are stored in Chrome's local storage (chrome.storage.local) and never leave your device.
The only network requests are to localhost:3100 (the Keyblind MCP server running on your own machine) to check vault status. No data is sent to external servers.
No user data is sold, shared, or transferred to any third party. No analytics, no telemetry, no advertising.
Keyblind is open source (MIT). For questions: github.com/aarifmms/keyblind/issues
