What does Stytch do with personal data?
Authenticate users and manage application sessions and access. That is how Privacyboard describes a typical use of Stytch, as a starting point you can edit.
The data usually involved: names, email addresses, user identifiers, IP addresses and authentication logs.
Is Stytch a processor or a controller?
Most customers use Stytch as a processor: it handles personal data on their instructions, for the purposes they set. That is the common reading for authentication 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 Stytch store personal data?
Stytch usually keeps data in the United States for every customer on its standard service, so there is normally nothing to choose. Privacyboard prefills this and you can change it if your setup differs.
How to find yours: Check your account settings or Stytch’s data processing terms for where your data is stored.
If the data is processed outside the European Economic Area, Articles 44 to 49 require a transfer mechanism, such as standard contractual clauses, an adequacy decision or the EU-US Data Privacy Framework. Your privacy policy should name it.
Does Stytch have a data processing agreement?
Checked on 1 November 2026. Vendors change their pages, so check the date.
Stytch 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: Stytch docs data compliance page linking to the DPA on Twilio's legal site. No date or entity named. States it operates exclusively from US servers and cannot support full data localization.
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.
