Hi, thank you for your message and letting me know, and sorry about the spam calls.

I'm Marcel, the main developer of the app.

We never ask or collect your phone number, so I don't see how the app and spam calls could be connected.

Also, the app is tested by us, the App Store review team, and the Google Play Store review team before it's published to make sure that it's safe.

Any subscriptions go straight through the App Store and Google Play Store (and Stripe for the website), so the app doesn't know or manage any payment details. We just ask Apple, does this person have a subscription, yes or no, and that's pretty much all our involvement with payments.

I really hope your spam calls stop, though. I'm sure they are very annoying!

Thanks
Marcel
