Is Proton Drive free?

At Proton, we believe everyone should have access to privacy on the internet. That is why we offer a plan for free cloud storage with Proton Drive. Unlike other cloud storage services, Proton Drive protects all files and folders with end-to-end encryption, no matter what plan you choose. For increased storage and features, you can upgrade to a paid account.

Does the free Proton Drive sell my data or have ads?

No, Proton Drive does not have ads, even on the free version, nor do we sell your data. The free version of Proton Drive is truly free forever. Proton Drive makes money through a freemium business model where users that upgrade to a paid plan help to cover the costs of providing a free service.

Is the free version of Proton Drive encrypted?

Yes. When it comes to security and encryption, we do not differentiate between our free and paid plans. All our plans come with end-to-end encryption by default.

What are the benefits of a free Proton Drive account?

With a free Proton Drive plan, all of your data is end-to-end encrypted by default, including your files, folders, names (both for files and folders), file extensions, file sizes, thumbnails, file previews, and more. This means it is protected from and can’t be monitored by Proton, shared with third parties, or exposed in a data breach. This makes Proton Drive the most secure free cloud storage service.
