Donations - How to Change Occurrences?

Dear Friends—

I very much appreciate the efforts of so many that have made Writer and the other applications useful and dependable tools. Writer in particular works better than ever on my older macOS (Mojave) and I am using it regularly.

So it only seemed write to give a few bucks to the cause. However, when I thought I was making a one-time donation I seem to have triggered regular, monthly withdrawals from my account. I would like to turn off the regular donations. Can anyone tell me how to do that?

Best Regards,

Glen
