About the GDPR

The General Data Protection Regulation (GDPR)(new window) is a European Union privacy law effective May 25, 2018. Any organization that collects, stores, or uses the personal data of EU citizens or residents must comply with the GDPR. Penalties for violations(new window) can be as high as 4% of global revenue or €20 million, whichever is higher. Learn more about how Proton Mail complies with the GDPR(new window). You can also read our GDPR overview(new window) on, a resource website operated by Proton Mail and supported in part by the Horizon 2020(new window) Framework Programme of the European Union.

Proton Mail encryption satisfies data protection requirements

The GDPR requires organizations to implement technical measures(new window) to protect the personal data in their possession: pseudonymization, anonymization, or encryption. The objective of these techniques is to reduce the potential for harm if personal data were to be breached.

Proton Mail uses end-to-end encryption(new window) and zero-access encryption(new window) to protect emails at all times. We cannot access users’ encrypted emails because we do not have access to users’ private encryption keys or passwords. These security measures guarantee that messages cannot be read, even if our servers were somehow breached.

If your organization shares or may share personal data via email, then using Proton Mail will ensure your email practices are compliant with the GDPR.

Proton Mail data processing agreement

For organizations using Proton Mail, we provide a data processing agreement(new window), which the GDPR requires for organizations that use third-party services. This agreement establishes the rights and obligations of both parties under the law.
