Ciroapp score

4.1/ 5

Proton Drive stands out with zero-access encryption, Swiss jurisdiction, and open-source code that's regularly audited. The permanent free plan, encrypted Docs and Sheets, and bundled apps add real value, though exact prices hide behind the pricing page and free users can't share files over 5 GB. Overall, it's a solid, recommendable pick for privacy-first cloud storage.

Pros

Pros:Zero-access, end-to-end encryption covers files, photos, and even file names before anything leaves your device, so Proton itself cannot read your data
Pros:Swiss jurisdiction places your files under strict European privacy laws, outside US and UK legal reach, and the code is open source with regular independent audits
Pros:Share links support password protection and expiry dates, and any link can be revoked instantly with a single click

Cons

Cons:Sharing files larger than 5 GB requires a paid upgrade, which limits the free plan for anyone sending big files
Cons:Exact dollar prices aren't shown up front on the main page — you have to check the pricing page for final amounts before committing
Cons:Long file version recovery (up to 10 years) is locked behind Drive Plus, so free users lose that safety net

Best for

Privacy-first individuals who don't want their cloud provider reading their files
People backing up photos and videos with automatic mobile backups and shared albums
Anyone sharing sensitive documents who needs password-protected, expiring links

Money-back guarantee: Yes — 30 days

What is Proton Drive?

Big Tech cloud storage often means your files get scanned and your data gets monetized. Proton Drive flips that. It encrypts everything end-to-end, so only you and people you choose can see your files — not even Proton.

You get a free 5 GB plan, protected sharing links, and apps for every major device.

Proton Drive is end-to-end encrypted cloud storage from the creators of Proton Mail, based in Switzerland. It stores files, photos, and videos, syncs them across Windows, macOS, Android, iOS, and the web, and includes online document and spreadsheet editors. There's a personal version and a separate business version.

It suits people and teams who want cloud storage without handing over access to their data.

Should you choose Proton Drive?

Quick buyer guidance before you compare plans or click through.

Choose it if

Buyers who want to test encryption at no cost — the free plan includes 5 GB, Docs, and Sheets
People who value Swiss jurisdiction and European privacy protections
Users who trust open-source software with independent audits over closed systems
Couples or households — the Duo plan covers two users with 2 TB of storage
Anyone switching away from ad-supported Big Tech storage, with guides for moving from Google Drive and Photos

Skip it if

Free users who need to send large files — sharing files over 5 GB requires a paid upgrade
Shoppers who want exact dollar prices up front — this page shows plan sizes and discounts but not final amounts, so check the pricing page before buying
Anyone who needs long version history on the free plan — 10-year file version recovery is a Drive Plus benefit
Buyers who depend on a wide third-party app ecosystem — the site highlights its own apps (Docs, Sheets, VPN, Mail) rather than marketplace integrations
Teams with strict compliance needs — business compliance details (GDPR, HIPAA, ISO 27001) live on separate business pages, so verify them before committing

Next steps before buying

1Compare the four personal plans — Free (5 GB), Drive Plus (200 GB), Unlimited (500 GB plus VPN), and Duo (2 TB, two users) — on the pricing page to find the right storage size.
2Confirm the apps you need exist for your devices — Windows, macOS, iOS, Android, web, or CLI — before paying.
3Check current prices and whether monthly or yearly billing suits you; paid plans come with a 30-day money-back guarantee.
4Decide if a bundle adds value for you — Unlimited and Duo include Proton VPN, Mail, Calendar, and Pass.
5Start with the free plan: upload a few files and create a password-protected share link to confirm the workflow fits before upgrading.

Ease of use

Signals point to a simple setup. You can create a free account and upload files by dragging and dropping into the web app or using the upload button. Native apps cover Windows, macOS, iOS, Android, and the web, plus a CLI. Windows users can sync any desktop folder automatically. User testimonials on the site praise a clean interface, and Proton offers a support section, blog guides, and a public roadmap.

Proton Drive Key Features

✨ Encryption starts on your device

Your files, photos, and even file names get encrypted right on your device, before anything is uploaded. Proton never holds the keys, so only you — and the people you choose — can read your data. Not even Proton can.

The same protection covers everything you store.

✨ Share links you fully control

Sharing something sensitive? Create an encrypted link, then add a password and an expiry date. Changed your mind?

Switch the link off with one click. It works for files, photos, documents, and spreadsheets, so you decide who gets in and for how long.

📸 Photos that back themselves up

Turn on mobile backups and your new photos and videos save themselves to the cloud. From there, you can build collaborative albums, so reliving and sharing favorite moments with family is easy. And like everything in Drive, your memories stay encrypted throughout.

✨ Synced across all your devices

Drive runs on Windows, macOS, Android, iOS, and the web, plus a command-line option. On Windows, you can sync any desktop folder. Change, add, or remove a file, and the cloud copy updates to match.

Your latest work is simply everywhere you are.

✨ Create and collaborate privately

You don't have to leave encrypted storage to get work done. Built-in editors handle writing and planning: - Proton Docs protects your words from data exploitation, surveillance, and AI training. - Proton Sheets supports formulas and charts for finances, reports, and workflows.

Both run in your browser, with sharing you control.

Use Cases

🔐 Share sensitive files without worry

Sending contracts, IDs, or medical records? Share them with a link protected by a password and an expiry date. If something changes, switch the link off with one click.

Expected outcome: only the right people open your files, and nobody else can.

📸 Back up and relive your memories

Turn on automatic mobile backups, and your photos and videos upload encrypted straight from your phone. Build shared albums so family can add and enjoy moments together.

Tip: the free 5 GB plan holds more than 1,000 high-resolution photos.

🔄 Keep work in sync everywhere

Sync any folder on your Windows desktop, and your latest edits appear in the cloud automatically. Pick up your files later on macOS, iOS, Android, or the web.

Expected outcome: your current work is ready on whatever device you're using.

📝 Create and collaborate privately

Draft documents and build spreadsheets with Proton Docs and Sheets, encrypted so your words stay off data-harvesting and AI training. Teams can share files and manage access with Drive Professional.

Tip: paid plans include a 30-day money-back guarantee.
