What does Didomi do with personal data?
Show cookie notices, record visitors’ consent choices and manage privacy documents. That is how Privacyboard describes a typical use of Didomi, as a starting point you can edit.
The data usually involved: account identifiers, IP addresses, website & device data, visitor consent choices, pages where consent was given
Is Didomi a processor or a controller?
Most customers use Didomi as a processor: it handles personal data on their instructions, for the purposes they set. That is the common reading for consent management tools and it is what Privacyboard suggests.
As a processor, it needs a written agreement with you under Article 28, and you should know which subprocessors it uses. Confirm the role against your own agreement, because the way you use a tool can change it.
Where does Didomi store personal data?
Didomi is usually associated with the European Union, but the location can depend on your plan or settings. Privacyboard prefills it as a starting point that you should check in your account.
What Didomi says (read on 12 November 2026): Sub-processors page: CMP, preference and DSAR data hosted by AWS in Frankfurt, Germany; statistics on Snowflake in AWS eu-central-1 (Frankfurt); server-side tagging (Addingwell) in Belgium. Source: didomi.io/sub-processors
How to find yours: Check your account settings or the provider’s data processing terms.
Even when the main location is in the EU, ask whether subprocessors or support access involve a transfer outside the EEA, and record it if so.
Which legal basis usually applies to Didomi?
For the usual use of Didomi, companies most often rely on legal obligation (GDPR Article 6(1)). Asking for consent before using cookies, and being able to show it was given, are required by law (GDPR Article 7(1) and the ePrivacy rules).
This is a starting point, not legal advice: the basis belongs to your activity, and you confirm it in your register.

Does Didomi have a data processing agreement?
Checked on 12 November 2026. Vendors change their pages, so check the date.
Didomi does not publish the full text of its data processing agreement on a public page. The reference page explains how a customer gets or signs it, usually from inside the account. Article 28 of the GDPR still requires a written contract, so get it and keep a copy.
What we noted when we opened the page: Didomi sub-processors page (last update July 2026): Didomi acts as processor when providing its services. CMP, preference and DSAR raw data hosted by AWS in Frankfurt, Germany; client data processing and statistics on Snowflake (AWS eu-central-1, Frankfurt); Addingwell server-side tagging in Belgium. DPA text not published on the page; dpo@didomi.io listed.
A page that exists does not mean you are covered. Whether the agreement applies to you depends on your plan and on what you accepted, so record the decision yourself in your vendor list.
