Does this affect Nextcloud?

I just got a Dreame L10 Pro from Amazon and flashed Valetudo on it. I’m super happy with it and with the local cloudless control. But it wasn’t particularly easy to do if you don’t have the hardware/linux knowledge required to flash it. Regardless the robot is very nice itself with mapping, lidar, and mopping.

Roborock looks great but is it usable offline or are you forced to export your home layout and unknown other data its collecting to china?
