- Encryption in transit: All traffic between the app and our servers is encrypted with TLS 1.2 or higher.

Note: While we implement comprehensive security measures, no system is 100% secure.
5. Data Retention
- Mood entries are retained indefinitely in your account for historical analysis and insights.
