Data Deletion

Last updated: 1 July 2026

Your Data, Your Device

SONARA operates 100% offline. No data is ever sent to our servers. Audio from your microphone is processed in real time and never recorded or stored. Measurement history and settings are stored locally on your device only.

How to Delete All Data

To remove all data stored by SONARA, follow these steps:

  1. Open Settings on your Android device.
  2. Tap Apps (or "Apps & notifications").
  3. Find and tap SONARA.
  4. Tap Storage & cache.
  5. Tap Clear storage and then Clear cache.

This will permanently remove all measurement history and settings.

Uninstalling the App

Uninstalling SONARA from your device automatically removes all associated data. No data remains on our servers because no data was ever sent to them.

What Gets Deleted

No Remote Data

Since SONARA does not collect, transmit, or store any data remotely, there is no account to delete and no server-side data to remove. Audio from your microphone is never recorded.
