In short, the app does not collect any user data, does not send usage or any activity to any server, device or service. In fact, there's not a single network request in the app, so nothing ever leaves your computer.
If you email me or contact me for support, or find anther way of getting your personal data in to my posession, I'll do evertthing I can to act reasonably and not share or sell that information.
That's it. No funny business. I'm here to sell an app that's for you to use, not make money doing things behind the scenes. If you've got any questions, just get in touch.
