ProtonMail, an encrypted email service, has removed a claim from its website that it does not log IP addresses after it was revealed that the company had provided IP address and device information to Swiss authorities, leading to the arrest of a French climate activist. The company's privacy policy states that it can be compelled to log IP addresses as part of a Swiss criminal investigation. ProtonMail has clarified that it only logs IP addresses when legally required to do so. The incident has raised concerns about the company's transparency and trustworthiness.
