We do not track any of your data. Either in the application or on the website. Purchases require an email address which we use to send you the license email, but nothing else.

It is conceivable it'd be used to send you an email once in the far future when I absolutely need to reach everyone that ever bought a license, but I cannot currently imagine what would prompt that.

The app does not currently gather anonymous usage information, but if it ever will, it'll ask you for permission first, and you're fully welcome to reject it.

If you do find anything I missed that could conceivably track you. Please let me know and I'll see if I can do anything about it.
