We are indeed starting to experiment with analytics, and aim to offer analytics as a service in the future.
We are tracking various info about the app and location, which will help understand better where JUCE-based apps are used, on which OS, which in turn will help us understand our users better and what to prioritise.
Users on the Personal or Education license will not be able to opt out of the analytics tracking, but Indie and Pro may subscribe voluntarily to it.
Another option to opt out, if you’re so inclined, is to use JUCE under the GPL license. As long as you release the code alongside the application, you can do what you want with it.
@matkatmusic, we do expect users to be honest
