About this list
Rieck uses a number of suppliers to run the portal — for hosting, operations, dispatch of email and physical letters, payment processing and support. They process personal data on Rieck’s behalf and are known as sub-processors.
This list is annex B to the data processing agreement and constitutes the general authorisation the client grants under § 6 of that agreement. It covers the suppliers that process information in the portal. Where Rieck is a processor for the client — customer due diligence and bills, cf. § 2 of the data processing agreement — they are sub-processors. Where Rieck is an independent controller for the information about the client’s debtors, the same suppliers are Rieck’s own processors.
Suppliers that Rieck uses as an independent controller in collection cases — collection agents, lawyers, hauliers, auction houses, credit reference agencies — do not appear here. They are set out in § 5 of the privacy policy for debt collection.
The list describes vendor processing and transfer safeguards. Mistral’s location information was checked against its Trust Center on 30 September 2026. Actual processing depends on the features used.
