1. Protect your data
- Encrypt your files: Tella automatically encrypts your photos, videos, and audio recordings as soon as they are captured.
- Hide your files in the device: your files are inaccessible from the phone’s regular gallery or file explorer. You can only access them in the app.

- Mask the app: change the look of Tella to hide it from people searching your phone.
