Because this app does not require sign-up or membership registration, there is no account to close.
The app never charges you automatically, and it never sends your data to our servers, so you can safely leave the app on your device.
If you still want to remove the app, simply delete it from your Home Screen, and that is all there is to it.
We are sorry to see you go, but we are very glad you used our app. We hope you will think of us again if you ever need it. Thank you very much for using our app.
