I am a EU citizen, I bought a (Chinese) robotic lawn mower. One day, end of April when the grass is growing very rapidly, they presented me with a dialog in the app that basically said. "We updated the EULA with the explanation "optimized wordings". Please accept." There was no reference to the new or old EULA, and if I didn't accept I could not start the app and use my new mower. It was bricked. I am now checking their compliance with GDPR. It is a tedious process because they keep stalling, but I still feel I have all the rights. And I get a lot of help from chatgpt who works as a patient secretary that translates my "f-fck sake give me my stuff" into formal/friendly legalese with counter questions designed to be difficult to duck. As of now, 2 months later, they have finally pointed me to "download personal data" in the application which gives me back a PDF with mower model, my email address and some push notification history. But I know they store much more than that. And I think they know that I know. If nothing else my customer support history. But also for example a map of my garden.
