Particle physicist Andy Yen's Proton Mail aimed to enhance online privacy in 2014. Now, Proton is challenging Google's dominance by launching encrypted document editing within its online storage system. This feature ensures only the creator and select individuals can access the contents, preventing data collection. Proton's move is a direct challenge to Google and Microsoft's data-hungry cloud services. By offering encrypted document editing, Proton becomes one of the few companies providing this level of privacy online. Proton's CEO, Andy Yen, highlights the importance of user-friendly privacy solutions, making their encrypted document editor resemble Google Docs for ease of adoption. With the launch of Proton Drive today, users can experience a clean document editor with standard features like text changes, formatting, and adding images. This innovation reflects Proton's commitment to enhancing online privacy and challenging tech giants in the industry.
