Wavelet Privacy Policy.

This app does not collect, store, use or transmit any personal information at all, it monitors the audio stream only when active and does not retain this data in any form.

It does ask for nor have permission to use the network connections or local data storage.

In fact it has one of the most minimal permission sets of any app I have seen, this is by design.

I don’t want to know anything about you

Very best regards.
