Before email confirmation, new registrations do not yet reserve a permanently confirmed participant place, but they are stored as pending. With Cleanup after, you can automatically remove these records after a freely selected number of minutes.

• 0 minutes: automatic cleanup disabled.
• Value > 0: the periodic cleanup routine may delete older unconfirmed records.

The value is also used for notices about the confirmation deadline. Placeholders such as {confirmation_timeout_minutes}, {confirmation_expires_at} and {confirmation_reservation_note} can output it in frontend and email texts.
