Do not rotate screen - Portrait only

I have normally turned on the auto-rotate screen feature from Android. When I wake up by the alarm and I’m in the bed I turned on to do a little bit maths with sleep as Android. Here my problem begins. :stuck_out_tongue_winking_eye:

The screens is always turning to an upright position, but I’m in bed, so my head is in horizontal potion. That’s to much for me. :wink: So I have to stop auto-rotate screen first and then I can stop my alarm.

It would be great if Sleep as Android could be in Portrait mode only, also when the auto-rotate feature in Android is turned on.
