 ## Data Retention and Deletion
+
+Wallet information remains in browser extension storage until the user removes
+it, clears the extension's storage, or uninstalls the extension. Temporary
+website access information expires when the wallet locks or the application is
+disconnected.
+
+Contractless does not maintain a separate developer-controlled database of
+extension wallets or user activity.
+
+## Sharing and Sale of Information
+
+Contractless does not sell user information. Information is not used for
+advertising, credit decisions, behavioral profiling, or purposes unrelated to
+the wallet's user-facing functionality.
+
+Information is transmitted only when necessary to complete a user-requested
+wallet operation, communicate with the configured Contractless API, or respond
+to an explicitly approved website request.
+
+The use of information by Contractless Web3 Wallet is limited to providing and
+improving its disclosed wallet functionality. Information is not transferred
+for advertising or other unrelated purposes, and humans are not permitted to
+read private wallet information except when specifically requested by the user
+for support, required for security, or required by law.
+
+## Security
+
+Contractless Web3 Wallet performs cryptographic operations locally using code
+and WebAssembly bundled with the extension. API communication must use HTTPS,
+except when a user deliberately configures a local development endpoint.
+
+No system can guarantee absolute security. Users are responsible for protecting
+their wallet images, private keys, encryption keys, devices, and configured API
+endpoints.
+
+## Changes to This Policy
+
+This policy may be updated when wallet functionality or privacy requirements
+change. Material changes will be reflected by updating this document and its
+effective date.
+
+## Contact
+
+Questions or privacy concerns may be submitted through the Contractless Web3
+Wallet repository:
