How We Protect Your Data
Industry-standard encryption, on-device calculations, and zero health data resale.
TLS 1.3 & AES-256
All communications between your iPhone and cloud storage are secured with modern banking-grade encryption.
Strict Account Isolation
Database security rules ensure your private fitness records and workout history can only ever be accessed by you.
On-Device Apple Health
Apple Health data stays on your iPhone. We calculate your daily energy targets locally without sending raw health streams to advertisers.
1. On-Device Storage First
RecalFit is built natively for iOS. Your workouts, past sets, and profile settings are stored securely on your phone. Even if you lose internet connection in a basement gym, the app continues to work smoothly without interruption.
2. Secure Cloud Sync
When you choose to back up your routine or check in on a new device, your data is synced using secure authentication tokens over encrypted connections.
3. Zero Data Resale
We do not sell, rent, or monetize your health data. We do not use third-party advertising SDKs or data brokers. Our revenue comes directly from premium app subscriptions.
4. Security Disclosures
If you are a security researcher and discover a potential vulnerability, please report it to our team so we can address it immediately.
