What the record says

Provider statement

Proton’s September 2021 response says Swiss authorities issued a binding order in the case of a French activist, and explains targeted IP logging obligations for Mail accounts.

Data outcome and relevance

Provider statement

The episode concerns targeted account/IP information in Proton Mail. It is not a documented Proton VPN traffic-log handover.

Company response or subsequent action

Provider statement

Proton said it could not appeal that request and distinguished the legal treatment of Mail and VPN. The page includes a subsequent court-ruling update.

Unresolved / not established

What remains unestablished

The underlying order and resulting disclosed dataset were not reviewed. The response does not support treating every Proton product as having identical obligations, or treating its 2021 legal explanation as a permanent statement of law.
