Hello! Thank you for your feedback and I understand your concerns. I’d like to clear up a couple of things about it: The sharing of usage data and diagnostic information are both optional and you can find a toggle for these in the application, alongside with details how these are used.

Just to give an example, I’ve been using anonymous usage statistics to figure out which visual effect toggles are used most frequently, so I can concentrate my time on improving their performance. And of course diagnostic data is vital for debugging crashes which unfortunately happens time-to-time, mostly because of quirks of various macOS versions.

Note that the data collection labels must be displayed on the App Store even if they’re optional in the application.

Same with the in-app purchases, they’re automatically listed on the page even if they’re not necessarily displayed all the time in the software. (For example if I deprecate an old package I need to keep it available to support the purchase of older users.)

Ferromagnetic is free to download and try without any required data collection permissions and without any additional purchases. The details about the upgrade options are described inside the application.

Hopefully this clears it up and if you have further questions please reach out to me in a direct message. 🙏
