1. Go to Settings > Kitchen Settings > Cut Off Timer.
2. On the Meal Prep tab, switch on the toggle for each weekday on which you want a cut-off to trigger (this is the day the rule runs, not necessarily the delivery day).
3. In How many days to close? enter 0–7: how many days ahead (starting from that weekday itself) will be closed when the rule fires.
4. In Time to close pick the time of day the rule fires (the picker offers 01:00–22:59).
5. Read the explanation that appears under the row, e.g. "On Friday at 12:00 it will close Friday, Saturday, Sunday", and adjust until it matches your operation.
6. Click Save. A green Done! confirms.

Weekdays left switched off never trigger a close. Typical example: deliveries on Monday and Thursday, ordering closes Friday noon for Monday and Tuesday noon for Thursday → enable Friday with 3 days at 12:00 and Tuesday with 2 days at 12:00.
