What is not on this list
Live voice runs on our own server: it passes through no third party, so no provider appears for it. The certificate authority and image registry we use see no personal data. We prefer a shorter accurate list to a long cautious one.
Changes
Any provider added or removed is published on this page. If you are a customer and want advance notice, tell us: it is a right the data processing agreement provides.
