Partly: read the fine print
Proton Drive is a vendor in a country with an EU adequacy decision, but we have not been able to confirm EU data storage as standard. Check where data is actually processed before you put personal data in the tool.

How to use it more safely

- Read our GDPR guide for small businesses for the full picture.
Common questions
Does Proton Drive store data inside the EU?

Is Proton Drive covered by the CLOUD Act?

What is needed to use Proton Drive in a GDPR-safe way?
Sign a data processing agreement (DPA) if the tool processes personal data on your behalf, minimise the personal data you feed in, and check the vendor's sub-processors. See our DPA guide for the steps.
