General notes to the beta testing program:

  1. Please note that beta software is a preliminary level of development and that's why the software can still show bugs and disturbances. To detect those we need you as tester!

  2. Each beta software has an expiration date. Afterwards each tester has to download the meanwhile officially released live version or a new beta version in order to continue using its TEASI in full extent.

  3. Before using the beta software please make a backup of your current data status on your device (in settings of TAHUNA TOOL). In order to switch again to live version the device has to be reset to factory settings. Thereby user data can get lost.
