We require personal data (social data) in order to carry out our tasks correctly. The legal basis for this is Section 284 German Social Security Code, Book V [SGB V] and Section 94 German Social Security Code, Book XI [SGB XI]. The information about TK's data processing pursuant to Article 13 DSGVO [EU General Data Protection Regulation] is available on tk.de/dataprotection.Hereby I am informed that TK informs the sales partner for billing purposes about a membership that has come about.
