How do I turn off automatic receipts?

The owner turns the switch off in Settings. Instructors do not have access to this setting.

1. Open Settings (/settings), Payment receipts section.
2. Turn off Automatically send a receipt after each payment, then tap Save.

From then on, confirming a payment no longer sends a receipt. To send one: student profile, Payments card, Send receipt (the owner and the instructor can). The switch is on by default.

What still goes out: a corrected receipt (if a payment is edited after a receipt was sent) and the cancellation notice ("Receipt No. … cancelled"), so nobody keeps a wrong receipt.
