Sub-processors

The providers that handle your data on our instructions, what each one does, where it runs, and the notice we give before changing the list.

A sub-processor is a company we use to run part of the service. Each one acts on our instructions under contract. We do not sell personal data.

​

The providers that run during a call only (conversation reasoning and voice generation) see the audio or text while the call is live. Nothing is stored with them and nothing is used to train their models. See Where your data lives for the transfer safeguards.
