Google Drive vs Proton Drive

How Proton Drive, a European File sharing tool, compares with Google Drive on the signals a privacy-conscious buyer actually checks: who owns it, where it hosts, and its exposure to the US CLOUD Act.

In short

Proton Drive (Switzerland, Geneva — Swiss-based, end-to-end encrypted, CLOUD Act exposure: None) is the privacy-first alternative to Google Drive. Google Drive is part of US-incorporated Google Workspace, runs on US infrastructure, and has direct CLOUD Act exposure; crucially, Google can read your files because they are not end-to-end encrypted. Proton Drive inverts that: files are end-to-end encrypted so the provider cannot read them, operated from Switzerland by the Proton group, starting at €4 per month. The trade-off is ecosystem — Google Drive's real-time Docs collaboration and integrations are deeper.

Verdict

Google Drive vs Proton Drive: which should you pick?

For storing files you would rather a provider could not read, Proton Drive is the strongest privacy alternative to Google Drive — because the difference is encryption, not just hosting region. Google Drive is US-incorporated (Google Workspace) on US infrastructure with direct CLOUD Act exposure, and stores your files in readable form. Proton Drive (Geneva — Swiss-based, CLOUD Act exposure: None) applies end-to-end encryption so the content is unreadable to the provider.

The real trade-off is collaboration, not sovereignty. Google Drive's real-time Docs editing and Workspace integrations are ahead. Proton Drive is built around private, encrypted storage and sync.

Pick Google Drive if live collaborative editing and deep Workspace integration are central to your work. Pick Proton Drive if end-to-end encryption and Swiss jurisdiction matter more — the right choice for confidential documents and for anyone already using Proton Mail, Pass, or VPN who wants storage in the same encrypted ecosystem.

Switching

Migrating from Google Drive to Proton Drive

Google Drive-to-Proton Drive is a folder move plus a Google-Docs export step.

  1. Export native Google formats first. Google Docs, Sheets, and Slides are not standard files — export them to Office (.docx/.xlsx/.pptx) or PDF via Google Takeout or per-file download before migrating.
  2. Download the full tree. Use Google Takeout (or the desktop client) to pull your Drive into a local staging folder. Uploading from a local copy resumes more cleanly than transferring service-to-service.
  3. Upload to Proton Drive. Upload the staged tree to Proton Drive; the folder hierarchy is preserved and files are encrypted on the way up.
  4. Reissue share links and remove Drive access. Recreate any active share links from Proton Drive (the old Google URLs cannot be ported), confirm your most-used files, then wind down Google Drive once everything is verified.
FAQ

Google Drive vs Proton Drive — frequently asked questions

What's the core difference between Google Drive and Proton Drive?
Encryption and jurisdiction. Google Drive stores your files in readable form on US infrastructure — Google can access them, and the US CLOUD Act reaches Google regardless of data location. Proton Drive encrypts your files end-to-end, so the provider cannot read them even if compelled, and is operated from Switzerland with CLOUD Act exposure: None. For sensitive documents, that end-to-end encryption is the substantive difference, not just the hosting region.
Does Google Drive fall under the US CLOUD Act?
Yes. Google Drive is part of Google Workspace, operated by Google LLC, a US-incorporated subsidiary of Alphabet, so it is directly within the reach of the US CLOUD Act regardless of where files are stored. Because Drive files are not end-to-end encrypted, a legal request can in principle reach readable content. This combination — US jurisdiction plus provider-readable files — is what drives the search for an encrypted alternative.
Is Proton Drive really end-to-end encrypted?
Yes. Proton Drive applies end-to-end, zero-knowledge encryption to your files and file metadata, meaning the content is unreadable to Proton and during transfer. Combined with Swiss operation (CLOUD Act exposure: None) and Proton's published audits, this makes it suitable for confidential documents where provider-readable storage is unacceptable. The encryption is the point: it removes the question of what a provider could be compelled to hand over.
Will my Google Drive files transfer to Proton Drive?
Yes. Download your Google Drive files (directly or via Google Takeout), then upload them to Proton Drive — the folder structure is preserved. Two things to plan: native Google Docs/Sheets/Slides export to Office or PDF formats first (they are not stored as standard files in Drive), and shared-link URLs change, so you reissue any active share links after the move.
What do I lose moving from Google Drive to Proton Drive?
Mainly real-time collaborative editing and the Workspace ecosystem. Google Docs/Sheets/Slides multiplayer editing is best-in-class, and Drive integrates tightly with Gmail, Calendar, and third-party apps. Proton Drive focuses on private, encrypted storage and sync; its document collaboration is newer and lighter. If your work depends on live co-editing, pair Proton Drive with a separate collaborative editor; if your priority is encrypted, sovereign file storage, it is built for that.
Is Proton Drive cheaper than Google Drive?
They are comparable, with bundling as the deciding factor. Proton Drive paid storage starts at €4 per month and is included in the Proton Unlimited bundle alongside Mail, Pass, and VPN. Google Drive (Google One) has its own tiers from a similar entry price. If you use other Proton services, Drive effectively comes with them; otherwise compare the per-GB tiers at the storage level you need.
