Sub-processors

To run Sustys we rely on a small set of vetted providers. We name them, say what each does, and tell you before the list changes — because a processor you can’t see is a processor you can’t assess.

Working draft — to be confirmed at launch · revised June 2026

About this list

A sub-processor is a third party that processes personal data on Sustys’ behalf to help deliver the service. Each is bound by a data processing agreement with terms no less protective than our own DPA, and is chosen to keep your data EU-resident wherever possible.

Pre-launch. The set below is our current intended configuration. It is confirmed with counsel before launch, and the live page will carry an effective date. Regions and roles in [review] are verified then.

How we change it

Before we add or replace a sub-processor that will process your personal data, we update this page and give advance notice — our intended notice period is 30 days. We keep the list current and versioned, with an effective date, so you can always see who handles your data today and what changed.

Objecting to a change

If you have reasonable data-protection grounds to object to a new sub-processor, tell us at legal@sustys.com within the notice period and we’ll work with you to find a resolution, as set out in the DPA. For how we secure data across these providers, see Security.
