If you wish to delete any data related to your activity on the app, please contact me. I'll be happy to do it.
If you find any security vulnerability that has been inadvertently caused by me, or have any question regarding how the app protectes your privacy, please send me an email or post a discussion on GitHub, and I will surely try to fix it/help you.
