We implement industry-standard cryptographic and administrative security safeguards to protect your personal information against unauthorized access, alteration, disclosure, or destruction:

• Data in Transit: All communications between our apps and backend servers are encrypted using Transport Layer Security (TLS 1.3 / HTTPS).
• Data at Rest: Sensitive local configuration data stored on Android devices is encrypted utilizing the Android Keystore system and EncryptedSharedPreferences / Jetpack DataStore.
