Summary

The website is informational. The app stores all session-related data locally on your device — nothing is transmitted to any server. If you email support, we receive what you send.

App Data Security

• On-device only: All doses, sessions, profiles, check-ins, and preferences stay on your iPhone. No cloud sync, no server uploads.
• Biometric App Lock: Optional Face ID / Touch ID / Optic ID gate. When enabled, authentication is required every time you open the app.
• AES-256 Encryption: Optional encryption for all stored data. Encryption keys are stored securely in the device keychain.
• No usage analytics: We do not track what you log in the app. Zero telemetry on substance use data.
