Subprocessors
A public list of key service providers. Kalbomatas is in testing and development, so the relevant provider depends on the function enabled at the time, the technical configuration, and the context of use.
Last updated: 10 July 2026
This page is the canonical public list of key providers used by Kalbomatas. A provider may act as a subprocessor when it processes data on our behalf, or as another service provider needed for a particular feature, security, payment, support, or Service operation.
Not every provider is used for every user, session, plan, or feature. When a provider is needed, the relevant processing is also explained in the Privacy Policy.

Transfers outside the EEA
We prefer processing in the EU and EEA. If a provider’s operation involves an international transfer, we use applicable legal mechanisms, including Standard Contractual Clauses (SCCs), and assess supplementary technical and organisational measures. More information is available in the Privacy Policy.
Changes and notices
We may add, change, or remove a provider because of security, Service continuity, feature development, legal requirements, or the testing stage. We reflect material changes on this page and, where required by law or contract, notify affected users by email.
