iOS SDK issue properties

I have just started adding the Sentry SDK to our iOS App.
While testing I noticed the SDK collect the following info

Where can I find info about them? They are pretty much self-explanatory but two of them captured my attention:

  • app.device
  • user

How are they generated? We need to know to understand if we are complying with privacy/GDPR rules. Thanks for the help

FYI

Got a reply from Sentry: they use installationId and identifierForVendor to generate those 2 properties.
