Subprocessors
Last updated · June 19, 2026
The third-party providers that process data to deliver Kleos, and what they receive.
How we use subprocessors
To deliver Kleos we rely on a small set of trusted third-party providers ("subprocessors") that process data on our behalf. We require appropriate data-protection terms with each, and where personal data leaves the EU/EEA we rely on Standard Contractual Clauses or another valid transfer mechanism.
This list is maintained and may change as we add or remove providers; material changes are reflected here.
