Open Account & plan, then Your account, and choose Delete your account. The FullDiary app has it too. It takes a few short steps: you say why you are leaving, and then you type the word DELETE to confirm.
What it does: it closes any business you own on your own. Its booking page goes offline and its customers get no more reminders, review requests, rebooking nudges or repeat bookings. The business is archived out of sight, and its invoices and quotes are kept as financial records for six years. It then deletes your login.
It is refused while a business you own on your own is on a paid plan, so cancel Pro first, under Account & plan, Your plan. A plan bought in the app is cancelled in the App Store or Google Play.
If you only want to take bookings offline for a while, you do not need to delete anything: Take it down on the link card in Shop settings closes the page to customers, and bookings already made stay.
