Secure your files with end-to-end encryption

Proton Drive is an encrypted secure cloud storage platform from the same team that created Proton Mail — the world’s biggest encrypted email service. You can use Proton Drive to save your files in the cloud, where no one will be able to access them except yourself and anyone you share them with. Thanks to our zero-access and end-to-end encryption, even Proton cannot view or edit your files.

Proton Drive will always offer a free cloud storage option that provides basic drive features and the same level of encryption as any of our paid plans. If you upgrade to a paid Proton Drive plan, you will be able to take advantage of additional storage, increasing your drive capacity up to 500 GB. With Proton for Business, you can customize your storage capacity to any size you wish. You will also be supporting our mission to build a better internet where privacy is the default.

You can upgrade your Proton Drive plan at any time by logging into your account at drive.proton.me(new window) and clicking Upgrade in the top right corner of your screen. From there, you can select the plan that’s right for you, depending on how much storage you need.

With Proton for Business, you can customize your storage capacity to any size you wish.

We provide a money back guarantee for all our subscriptions. If you cancel your subscription within the first 30 days of the initial purchase, you will receive a refund of the unused portion of the service. This refund is calculated on a pro-rata basis. Beyond the first 30 days of purchase, refund requests will only be processed at the company’s discretion.
