Sub-processors

Every third party that can process personal data on behalf of our customers, what reaches each one, and where it is processed.

Draft — not yet reviewed by legal counsel

This document describes how the product actually works, but it has not been reviewed by a qualified lawyer and some company details are still outstanding. It is published for transparency and is not yet a binding legal document. Anything marked ▲ to be supplied is a known gap.

Our commitment

The data processing agreement requires us to keep this list current and to give notice before we add to it. If a new provider is introduced into the service and it can touch personal data, it appears here — in the same change that introduces it.

  • Notice before addition. We give at least 30 days’ notice before a new sub-processor starts processing customer data.
  • A right to object. A customer that reasonably objects on data-protection grounds can raise it with us, and if we cannot resolve it, terminate the affected part of the service without penalty.
  • Flow-down obligations. Each sub-processor is bound by written terms no less protective than those we owe our customers. We remain responsible to the customer for their performance.

What is deliberately absent

It is as useful to know what is not on this list. We use no analytics provider, no advertising or marketing platform, no customer data platform, no session-recording tool, and no third-party AI or machine-learning service. Customer data is not sent to any of these, because none of them are part of the product.

Getting notified of changes

To be told when this list changes, email Privacy contact address — to be supplied and ask to be added to sub-processor notifications. Notice goes to the administrative contact on each account by default.
