How long we keep data
Enquiry data is retained for as long as needed to handle the enquiry and any resulting project. If no project follows, enquiries are typically deleted or archived after a reasonable period, unless a legal retention obligation requires longer storage.
Legal retention obligations under German commercial and tax law may require certain business correspondence to be retained for the statutory period. Where that applies, the data is restricted to that purpose — kept for the record, not used for anything else.
