Subprocessors
Last updated: 6 November 2026
DentroChat uses the following third-party subprocessors to provide our service. All subprocessors are located within the European Union or in Switzerland, whose data protection law (FADP) is closely aligned with GDPR and recognised by the EU as adequate.We do not use any US-based subprocessors.
We contract directly with the providers listed under Third-Party Subprocessors. AI chat inference is handled by Cortecs, which carries it out on the European inference providers listed further below. We do not contract with those providers directly. Where more than one provider can perform the same function, we may use any of them, so this page lists all of them instead of only those in active use at a given moment. Each provider may engage its own subprocessors which are disclosed by the provider concerned itself.
