Database Encryption
SQLCipher with AES-256-CBC. Your database is encrypted at rest. Without your password, the file is unreadable — even to us.
Credential Protection
API keys and database credentials are encrypted using your operating system's built-in protection (Windows DPAPI) — the same standard used by Chrome, Git, and Docker. Your secrets are tied to your Windows login and never stored in plaintext.
Zero Telemetry
No analytics. No crash reporting. No usage tracking. No phone-home. The application works fully offline after initial setup.
No Account Required
No sign-up, no email, no personal information collected. License validation is a one-time check — it doesn't transmit your data.
