Local-First Architecture
Symbiota follows a local-first data architecture. All health data — food logs, symptom records, pattern detection results — is stored primarily on the user's device using encrypted local storage.
This means your most sensitive health data never needs to leave your phone. Pattern detection and AI coaching can operate on locally-stored data without requiring cloud processing for core functionality.
End-to-End Encryption
For users who opt into cloud sync (for backup and multi-device access), all data is encrypted end-to-end using AES-256 encryption. Encryption keys are derived from user credentials and never stored on our servers.
This means that even in the unlikely event of a server breach, encrypted health data would be unreadable without the user's individual encryption key.
No Data Monetization
We do not sell, rent, or share personal health data with third parties for any purpose — including marketing, advertising, or data brokerage. This is a fundamental principle, not just a policy.
Our business model is subscription-based. We make money when users find the app valuable enough to pay for Premium, not by monetizing their health data.
User Rights & Control
Users have full control over their data: the right to access, export, correct, and delete all personal data at any time. Data export is available in standard formats for portability.
Account deletion results in complete removal of all associated data from our servers within 30 days, with immediate removal from active systems.
