    Cloud storage is where the most personal things end up — your documents, your photos, the scans of your ID. With Google Drive, Dropbox or iCloud, the company holding those files also holds the keys to them, and can scan, analyse or hand them over. Proton Drive is the deliberate opposite: encrypted cloud storage where your files are scrambled on your device before they upload, so not even Proton can open them. If you’re moving off Big Tech, it’s the private alternative to Google Drive.

    What makes Proton Drive different

    Your files are end-to-end encrypted by default. Everything — the files, your photos, even the file names — is encrypted on your device with keys only you hold, before it ever reaches Proton’s servers. This is ‘zero-access’ encryption: even Proton’s own staff, handed a court order, can produce nothing but unreadable data. Google Drive and Dropbox hold the keys to your files, so they — and anyone who can compel them — can read what’s inside.
    It’s built for privacy, not advertising. Proton Drive is part of the wider Proton suite, based in Switzerland, paid for by subscriptions rather than ads, and open-source and independently audited. There’s no business reason to mine your files, and the encryption can be checked by anyone rather than taken on trust.

    Proton Drive vs Google Drive

    On the surface they do the same job — store, sync, back up and share your files. The differences that matter are underneath:

    Your files are unreadable to the provider

    Proton can't open your files; Google can scan what's in your Drive, and does

    You hold the keys

    Only you can decrypt your files, where Google holds the keys and can be compelled to hand them over

    Built for privacy, not ads

    Proton runs on subscriptions, so there's no business reason to mine your files or photos

    Part of the encrypted suite

    One Swiss account shared with Proton Mail, VPN and Pass, all under the same protection

    What you get with Proton Drive

    Store anything with the same zero-access encryption as the rest of Proton

    Automatic photo backup

    Back up your camera roll on iPhone and Android, encrypted end to end

    Secure sharing

    Share files with password-protected links that can expire, without exposing them to the host

    Version history & recovery

    Roll back to earlier versions and recover deleted files within the retention window

    Works everywhere

    Proton Drive

    End-to-end encrypted cloud storage for your files and photos — private by default, on the same Swiss account as the rest of Proton.

    Get Proton Drive

    Is it worth paying for?

    There’s a free tier with a few gigabytes, so you can try it at no cost. But the real value is in Proton Unlimited, which bundles far more Drive storage with Mail, VPN, Pass, Authenticator and Calendar on one account — usually for less than paying for a cloud drive and those tools separately. If you’re rebuilding your privacy anyway, keeping your files on the same trusted foundation as everything else is simpler and stronger than scattering them across providers.

    Common questions

    Can Proton actually see my files?
    No. Proton Drive uses end-to-end, zero-access encryption — your files, photos and even their names are encrypted on your device with keys only you hold, before they reach Proton's servers. Even Proton, handed a court order, can only produce unreadable data. Google Drive and Dropbox hold the keys to your files and can scan them.
    Is Proton Drive free?
    There's a free tier with a few gigabytes to start. The paid Proton Unlimited plan gives you far more storage along with the rest of the suite — Mail, VPN, Pass and more — usually for less than paying for a cloud drive and those tools separately.
    Can I use it like Google Drive or Dropbox?
    Yes. You can upload and organise files, back up your phone's photos, and share with links — the everyday things you'd expect — with encryption added underneath. Apps are available for iPhone, Android, Windows, Mac and the web.
    What happens if I forget my password?
    Because only you hold the keys, Proton can't unlock your data for you — that's the point. Set a recovery method when you create your account and store your recovery phrase safely, so you never lose access.
    Is it a real alternative to Google Drive?
    For most people, yes — storing, syncing, backing up and sharing files is all there, with privacy Google can't match. The main trade-off is a smaller ecosystem of third-party integrations, which most everyday users never notice.
