Not really sure what this is good for. It doesn't auto sync files outside of the app so your photos and stuff aren't backed up and other apps can't access the files in the app directly. You have to download them first but then updates won't be synced. Plus the PC version won't auto sync files on a network drive. This service is so tedious to use that it's barely useable at all.

Hi Stephen! We have recently introduced the Proton Drive Windows client ( to support syncing your desktop files and folders. We are also working on adding automatic sync with end-to-end encryption across our mobile apps. Stay tuned for updates!

Not quite ready for prime time. The one glaring function missing is a Unified Drive - In other words, when I open the mobile app I should see and access files from my windows machine. When I open the Windows App I should see/access the My Files that are on the Android moble app. And the Local machine's 'Drive' Folder on my hard drive only shows the 'My Files' that are actually files from the Web interface placed there by drag and drop from the Local machine (Makes no sense)

Hi! We are working on implementing the 'Computer' section in our mobile apps. For the time being, however, you can access these files via the app, if you add them to 'My Files' on Windows. The files already uploaded to your drive are displayed in 'My Files' on Windows. Contact us at if you need help with this.

Was beyond excited to see this as I love their mail service. I did get disappointed not seeing an auto sync option and you having to manually put your photos into the drive but after reading other reviews, I am now excited again as it seems that it's in the works! Yay! So for that, I will rate it 4 stars until the auto sync comes out. I would do it lower but I just love this company a lot and the privacy they provide.

Thank you for your positive review and feedback! The sync functionality is indeed something we are working on and should arrive in the following months. So please bear with us, and we hope to earn a 5-star rating from you very soon!
