Proton Mail has come under scrutiny for its role in a legal request involving the Spanish authorities and a member of the Catalan independence organization, Democratic Tsunami.

Proton Mail is a secure email service based in Switzerland, renowned for its commitment to privacy through end-to-end encryption and a strict no-logs policy. In 2021, Proton Mail faced controversy when it complied with a legal request that led to the arrest of a French climate activist. Under Swiss law, Proton Mail was compelled to collect and provide information on the individual’s IP address to Swiss authorities, who then shared it with French police.

The recent case involving the Spanish police this time, highlights privacy concerns and the limits of encrypted communication services under national security pretexts, and brings a long-debated subject to the forefront once again.

The core of the controversy stems from Proton Mail providing the Spanish police with the recovery email address associated with the Proton Mail account of an individual using the pseudonym ‘Xuxo Rondinaire.’ This individual is suspected of being a member of the Mossos d’Esquadra (Catalonia’s police force) and of using their internal knowledge to assist the Democratic Tsunami movement.

Upon receiving the recovery email from Proton Mail, Spanish authorities further requested Apple to provide additional details linked to that email, leading to the identification of the individual.

This case is particularly noteworthy because it involves a series of requests across different jurisdictions and companies, highlighting the complex interplay between technology firms, user privacy, and law enforcement. The requests were made under the guise of anti-terrorism laws, despite the primary activities of the Democratic Tsunami involving protests and roadblocks, which raises questions about the proportionality and justification of such measures.

Like before, Proton Mail’s compliance with these requests is bound by Swiss law, which mandates cooperation with international legal demands that are formalized through proper channels (Swiss court system).

Last year, when we noted that Proton Mail complied with nearly 6,000 data requests in 2022, Proton provided us with an explanation that inbox contents remain secure.
