Certen Key Vault does not collect, transmit, or share any personal data. All data is stored locally on your device using chrome.storage.local. Private keys are encrypted with AES-256-GCM using a password-derived key (PBKDF2-SHA512, 600,000 iterations). No analytics or telemetry are collected. The extension requests host permissions solely to inject the window.certen provider API so decentralized applications can request transaction signatures. The extension does not read or modify page content.
