Sub-processors

Last updated: 5 November 2026.

What this list is for

When I work for you as a processor under the GDPR, I engage the parties below as sub-processors. This list belongs to article 5.2 of the terms and conditions. I have a business contract with a data processing agreement with each party. For services, I use AI tools only with terms and settings that rule out the provider using your inputs and outputs to train models (article 2.8).
