Cloud storage when full

i was looking into a more affordable security cams, wyze looks like its it. but if I don’t upgrade the cloud storage, how does it work when the cloud is full? does it continue to keep the new and delete the old, or does it stop storing on the cloud once its full?

Without subscribing to Complete Motion Capture (CMC), Wyze will store 12 second clips on motion/sound detection at most every 5 minutes for each camera for a 14 day period. When 14 days elapses, those clips are deleted.
