Proton

Proton, known for its privacy-centric services, has introduced a feature for creating, editing, and collaborating on end-to-end encrypted documents within its storage systems, challenging the practices of tech giants like Google and Microsoft. This innovation safeguards user data from third parties, including Proton, which cannot access the content of the files. The initiative enhances user privacy, directly confronting the data collection methodologies prevalent among leading cloud service providers. As a result, there have been no reported data leaks or negative consequences following the implementation of the encrypted document feature provided by Proton.
