German administrative offices in general don't talk to each other without your permission, with exceptions like the police. This is also the reason why it's e.g. a giant pain to change your name in Germany - everyone has their own independent database. Can you maybe clarify, please? BAMF has no data of German citizens ("Bundesamt für Migration und Flüchtlinge", Federal Ministry for Migration and Asylum Seekers). Schufa is a private company which only gets data from other companies, not the government. If you don't allow a company to give your data to the Schufa (which, to be fair, you have to do for many things), they cannot legally get the data (and in this case you could force them to delete it via GDPR). German administrative authorities don't even have compatible databases. Like, if you go from Munich to Berlin, they have to basically enter your data manually. The software of the local municipalities (Einwohnermeldeämter) have no common API, and up until a few months, there wasn't even a unique ID for every citizen which could be used as a key in databases. Law firms only can get some data if a court allows it. If you get e.g. a ticket for speeding, and you didn't drive your car, but your spouse did and you don't tell them who the person in the driver seat on the picture is, there is nothing they can do (except forcing you to, from now on, keep a log book of who drives your car). They can't just call your local municipality and get the ID pictures of your spouse or something.
