There's also an individual Proton Drive subscription that offers 200GB of storage for $3.99 a month.

Proton Drive offers a free version with 1GB of cloud storage, while users subscribing to 500GB of encrypted storage ($9.99/month) via the Proton Unlimited plan also get Proton Mail, Proton Calendar, and Proton VPN. Shared files are similarly delivered in an encrypted environment and can be downloaded securely by recipients. In addition, users can generate secure file-sharing links from the Proton Drive app that can be shared with others, even if they don't have a Proton account. Starting today, you can create a Proton account using any email address and access Proton Drive. If offline access is activated for a file or folder, they are encrypted and saved on-device so that they can only be accessed through the Proton Drive app. The apps also offer offline access to files and folders so they can be accessed without an internet connection. There are no file size limits, so users can share and transfer large files securely.

That includes associated metadata, such as file and folder names, real file size, file extensions, thumbnails, and more.ĭata uploaded and stored on Proton's servers reside in data centers in Switzerland and Germany, giving users strong legal and hardware protections (the company claims it falls outside US and EU jurisdiction and isn't subject to intelligence-sharing agreements). All files and folders uploaded to the storage service are protected by Proton's open-source, publicly-audited end-to-end encryption, which uses on-device encryption keys ensuring no one else – not even Proton – has access to the contents.
