The software application Entropy Piano Tuner (“Application”) uses the built-in microphone of the installed device to record the the spectra of each key of your piano.
Any information collected through the microphone is used only for calculating an optimal tuning in the Application. The Application will never send the data outside the device, or use it for collecting personal identifiable information.
You can set the device to deny the access to the built-in microphone from the Application. In that case, the Application cannot detect the spectra of your piano and therefore not compute a tuning. If you wish to use the Application, allow the access to the microphone.
