It's a custom OS. If you go to system update, you can find release notes: https://daylightco.notion.site/Daylight-Release-Notes-1040b673e0bf8049bfbaceb234ab523a

So yeah, the whole OS is covered by this garbage privacy policy that collects everything, including your pen strokes. I completely regret buying a DC-1. I already regretted it because I think the hardware feels cheap and the case creaks when I hold it in different positions... a $400 iPad has a better build quality than this. But this is totally unacceptable and I won't be using the device any more.
