1. Overview
Proton Drive brings the same privacy-first approach of ProtonMail to cloud storage. Unlike Dropbox, which can access your files, Proton Drive uses end-to-end encryption - your files are encrypted before leaving your device, and only you can decrypt them. For users who take file privacy seriously, Proton Drive offers what Dropbox fundamentally cannot: truly private cloud storage under Swiss jurisdiction.

3. Privacy & Security
Proton Drive uses end-to-end encryption for all files by default. Files are encrypted on your device before upload using keys that only you control. Even Proton cannot access your files - this is architecturally impossible, not just a policy promise. Combined with Swiss jurisdiction and strong privacy laws, your files have maximum legal and technical protection. Dropbox encrypts files in transit and at rest, but Dropbox holds the encryption keys. This means Dropbox can access your files and must comply with US government requests. Dropbox has previously had security incidents and changed privacy policies. For sensitive files, this is a fundamental limitation.
4. Pricing
Proton Drive offers 5GB free storage. The Plus plan (€4/month) includes 15GB. Proton Unlimited (€10/month) includes 500GB Drive plus Mail, Calendar, VPN, and Pass - excellent value for the complete privacy suite. Dropbox offers 2GB free, Plus (2TB) at €11.99/month, and Professional (3TB) at €19.99/month. While Dropbox offers more raw storage, Proton provides better value when considering the full suite of privacy tools included in Unlimited.

Winner: Proton Drive
Proton Drive is the clear winner for anyone who values file privacy. Its end-to-end encryption means your files are truly private - not even Proton can access them.

For personal documents, photos, and sensitive files, Proton Drive provides the peace of mind that your data is genuinely protected.
8. Frequently Asked Questions
Can Proton access my files on Proton Drive?
No. Proton Drive uses end-to-end encryption and zero-access architecture. Files are encrypted on your device before upload, and only you hold the keys. Even Proton employees cannot access your files. This is fundamentally different from Dropbox, where the company can access your data.
Is Proton Drive a full Dropbox replacement?
For most personal users, yes. Proton Drive offers file sync, sharing, and mobile apps. It lacks some Dropbox team features and third-party integrations, but for secure personal file storage and sharing, it's an excellent alternative with superior privacy.
Why does Proton Drive have less storage than Dropbox?
End-to-end encryption is more resource-intensive than standard storage. Proton also doesn't monetize user data to subsidize storage costs. The trade-off is less storage but complete privacy. Many users find 500GB with encryption more valuable than 2TB without.
Does Proton Drive work with other Proton services?
Yes, Proton Drive integrates with ProtonMail, Proton Calendar, Proton VPN, and Proton Pass. The Proton Unlimited plan includes all services, creating a complete privacy-focused ecosystem as an alternative to Google or Microsoft.
