Indeed. During the pandemic, restaurants in Germany were required to track customer's information including addresses, so people could be informed in case of a confirmed CoViD infection of another customer who was there at the same time. Of course, this information was never to be used for any other purpose whatsoever.
In one case, however, there was a capital crime near a restaurant (or similar venue) and police and prosecutor used this information illegally to track down witnesses. They were sued after the fact and lost, but got nothing more than a slap on the wrist.
Once information is available, it will be used for purposes other than the intended one, even by the "good guys".
