Sub-processors

Version v1 · Last updated: 29 June 2026

This page transparently lists every external service flintery uses — separated by whether they process your clients' contract data or only concern your own master data. It is the living list referenced in our data processing agreement (DPA § 6).

Only the German original version is binding. This English version is provided for information only.
