Proton Drive for Mac

Proton Drive for macOS — private cloud made simple

Proton Drive is a cloud storage solution for Mac that emphasizes privacy and security. Files are encrypted on your device before they leave, so only you can read them. The service is hosted in Switzerland and operates under strict Swiss data-protection rules, helping keep your information shielded from unwanted access.

Storage tiers and account basics

You can start with a complimentary account and expand as needed.

• 3 TB — available on higher-tier paid plans
• 200 GB — mid-level upgrade option
• 500 MB — free starter allocation

Upgrades are offered for users who need substantially more space. Plans are straightforward, letting you choose the capacity that fits your workflow.

How syncing and access work

Proton Drive lets you pick which folders to keep in sync, so you only store what you need on the cloud. Once your files are synced, they can be reached from any web browser after signing in to your account. The app is designed to be flexible: select specific directories to sync rather than forcing a full-drive mirror.

Security, transparency, and privacy practices

Proton Drive uses client-side (end-to-end) encryption so file contents remain unreadable to anyone without your keys. The project's cryptography is open-source, enabling independent security audits and community verification. Proton also aims to minimize data collection and delivers an ad-free experience, reinforcing a focus on user privacy.

When to consider an alternative

If your needs lean toward direct file transfers or FTP-style workflows rather than an encrypted cloud vault, consider using FileZilla (free) as a complementary tool. FileZilla is well-suited for moving files between computers and servers but does not provide the same client-side encryption and Swiss-hosted privacy guarantees Proton Drive offers.
