Your data stays with you

- Voice practice analyzes your microphone on your device. Audio is never uploaded, and recordings you choose to keep stay on this device.
- No analytics, ads or trackers.
- You can turn on an app lock: a PIN that locks Tendril when you leave it and encrypts everything it saves.
- You can back up your data to a file, protected with a password, and restore it on another device.
