You can sent the feedbacks in the app. The problem you can disable the sending of data for some categories. But I always have to scroll down for each category. Please make it better e.g. add an arrow button if users want to see what details are being sent. Then click on the arrow button.

I think it would be very good if the last setting remembers itself and is not hidden by default. I know some users who find it so much more intimate.

Tested with Briar 1.2.4 version
