What does xAI API do with personal data?
Support business activities or client services using the provider’s API or services. That is how Privacyboard describes a typical use of xAI API, as a starting point you can edit.
The data usually involved: documents & attachments, Prompts, outputs, any personal data included in API requests
Is xAI API a processor or a controller?
Most customers use xAI API as a processor: it handles personal data on their instructions, for the purposes they set. That is the common reading for ai services 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 xAI API store personal data?
xAI API does not have one fixed location for every customer. The location depends on the plan, the account and the services you enable.
How to find yours: Check your account settings, the address you log in to, or the provider’s data processing terms. Support can tell you if you cannot find it.
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 xAI API?
The legal basis for xAI API depends on what goes through it. The legal basis depends on what you send to the provider and why. Use the basis of the activity the AI supports in your register.
This is a starting point, not legal advice: the basis belongs to your activity, and you confirm it in your register.
Does xAI API have a data processing agreement?
Checked on 5 November 2026. Vendors change their pages, so check the date.
Yes. xAI API publishes the text of its data processing agreement on its own website. Article 28 of the GDPR requires a written contract with every processor, so this is the document to read and keep.
What we noted when we opened the page: Data Processing Addendum effective 22 Sep 2026, part of the Enterprise Terms of Service; page is branded SpaceXSI with data importer SpaceXAI LLC. Data may be processed globally incl. the US; transfers under EU SCCs, UK Addendum and Swiss SCCs.
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.
