What does Proton Mail do with personal data?
Deliver transactional emails such as account notifications and password resets. That is how Privacyboard describes a typical use of Proton Mail, as a starting point you can edit.
The data usually involved: recipient email addresses, message content and delivery metadata.
Is Proton Mail a processor or a controller?
Most customers use Proton Mail as a processor: it handles personal data on their instructions, for the purposes they set. That is the common reading for email 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 Proton Mail store personal data?
Proton Mail 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 sending domain or account settings for the region.
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.
Does Proton Mail have a data processing agreement?
Checked on 1 November 2026. Vendors change their pages, so check the date.
Yes. Proton Mail 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 Agreement modified February 10, 2026, for Proton AG. No single hosting region specified in the reviewed text.
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.
