In the Google Play Store app, tap your profile picture, then Payments & subscriptions → Subscriptions. Choose the app and tap Cancel. You keep access until the end of the period you have already paid for.

All purchases go through Google Play. Within 48 hours of buying, you can ask for a refund from your Google Play order history. After that, email us your order number (it starts with GPA.) and we'll look into it.

Open the app's settings and tap Restore purchases. Make sure you are signed in to the Google account you bought it with. If that doesn't fix it, send us the order number.

SmartBlock, Cycylr and ModbusBB keep everything on the phone, so uninstalling the app or clearing its data in Android Settings → Apps deletes it. XOClash, Stack Tower and Last Text have online accounts. For those, use the in-app delete option where there is one, or email us from the address or account you used and we'll delete it and confirm.

Ads pay for the servers and for development. Where the law requires it (the EU, the UK and elsewhere), the app asks for your consent first, and you can change your choice later in its privacy settings.

Possibly. We take on a small number of projects: Android apps, Windows tools and Modbus/SCADA integrations. Email us a short description of what you need.
