Your address and phone point to a location, not necessarily a valid identity but I understand you may be hesitant to share personal info with just anyone. If you are a EU citizen you can ask them exactly how long your data is retained and who may have access to it (it’s actually published on their website). They use it only as a 2nd level verification to prevent spam (not shared with 3rd parties). As a German/EU company, Hetzner is subject to all regulatory requirements for handling of personal information and so when leaving, you can also request the deletion of your data.
