Sub-processors

Last updated: 4 July 2026

This page describes the categories of third-party sub-processors Syntra uses to help deliver the Services, the purpose of each, and how we manage them - a current list of the named entities behind these categories is available on request.

1.About sub-processors

A sub-processor is a third party that Syntra ("we", "us" or "our") engages to process personal data on our behalf in order to help us deliver our platform and AI-powered services (the "Services") to you (the "Customer"). Where we act as your processor, we do so under our Data Processing Addendum, which sets out how we appoint and manage the sub-processors described on this page.

Before we engage a sub-processor, and throughout our relationship with it, we take steps to protect the personal data entrusted to us:

  • We impose data-protection obligations on each sub-processor by written contract that are no less protective than those in our Data Processing Addendum;
  • We assess each sub-processor's security and privacy practices before onboarding and on an ongoing basis, in line with our security programme;
  • We engage sub-processors only for the purposes described below, and only to the extent needed to provide, secure and support the Services;
  • Where personal data is transferred across borders, we put appropriate safeguards in place, such as standard contractual clauses, as set out in our Data Processing Addendum.

We remain responsible to you for the performance of our sub-processors' obligations.

2.Our sub-processors

We group our sub-processors by the role each plays in delivering the Services. The table below describes each category, its purpose, the broad category of data it may process, and the general region in which processing takes place. So that this page stays current and vendor-neutral, we describe each sub-processor by its role rather than by name; the current list of the named entities behind these categories is available on request (see The current named list).

The categories above reflect the roles a sub-processor may perform. Not every Customer's configuration engages every category - the sub-processors actually used depend on the features you enable and the channels you configure.

3.The current named list

We keep an up-to-date list of the named entities that sit behind each category above, together with the specific processing each performs. To request the current list, please email us at hello@syntra.ai. Where you have an agreement with us that requires it, we can also make the list available to you under our Data Processing Addendum.

4.Changes & notifications

As the Services evolve, we may add, replace or remove sub-processors. When we do, we will update this page, and where we act as your processor we will provide a way for you to be notified of new or replacement sub-processors before they begin processing personal data on your behalf, so that you have an opportunity to review the change.

  • To subscribe to notifications of material changes to our sub-processors, email us at hello@syntra.ai and we will add you to the notification list;
  • The mechanism, notice period and any right to object are governed by our Data Processing Addendum where it applies to you.

Material changes take effect only after the applicable notice period has passed, unless a change is required sooner to maintain the security or lawful operation of the Services.
