They have to provide the data on request. I also think they aren’t allowed to delete any data they have when you request it before providing it (although you can of course also request deletion).
Minnesota and some other states have similar laws that basically mirror GDPR. States have forms you can get that you would submit to the company. I’ve done it for my Matterport data after they started making you pay to unarchive content (originally free)
Honestly I would just try doing a GDPR request and see what happens. They first have to find out if you’re from the EU, and they probably will err on the side of caution and just fulfill it.
Actually when reading up more on it, it looks like you don’t have to be in the EU at all.
If I understand it correctly, the GDPR applies to any company that does business in the EU and it doesn’t even matter where the data subject is located or which country they are a citizen in.
So even if you’re from the US, you should be able to make a valid GDPR request.
