With the Proton Drive app, you can now access the encrypted file storage platform on your iPhone or your Android phone. This means that you can now take advantage of all the perks Proton Drive gives you, such as end-to-end encryption for all your files and their respective metadata, ensuring you, and only you, have access to your files.
Proton Drive’s mobile app also has some unique features, compared to the web experience. If you have an iPhone or an iPad, you can put in a PIN that will encrypt all Drive files you’ve stored locally on your device, ensuring that no one can access them unless they know that PIN. You can also securely share files with other people, even if they don’t have a Proton account — those friends can download files from an encrypted environment.
If you’re looking for a secure alternative to the Google Drive app on your phone, this might be it. Download it now from the Apple App Store or the Google Play Store. The company is still working on a Windows client, which should be available in beta “shortly,” followed by a Mac version.
