Proton Drive uses end-to-end encryption: File contents, filenames, and folder names are all encrypted with your private key before leaving your device. As we don't have access to your private key, we cannot access the files you upload to Proton Drive. Only you can access your data. This is known as zero-access encryption.

Please note that while the contents and names of your files are end-to-end encrypted, certain fields, such as file size, are not encrypted. We do this to enable certain server functions, such as sorting.

The size of the file you can upload is only limited by your available free storage space. In other words, if you have 10 GB of unused storage, you can store a file of up to 10 GB.

When you delete files in Proton Drive, it can take up to three hours to completely clear the storage space. If your storage doesn't clear automatically after three hours, please contact our Customer Support team. We'll be happy to help.
