Proton Drive review

Proton Drive is the strongest privacy pick here, because Proton states that its zero-access, end-to-end encryption means not even Proton can view or edit your files. The free plan gives 5 GB with no credit card and includes the online document and spreadsheet editor, so you can test it with real files before paying. Drive Plus adds 200 GB and 10 years of previous file versions; on the current offer it costs $2.49 a month, billed $29.88 for the first 12 months, then renews at $47.88 every 12 months. Proton Unlimited bundles 500 GB with Proton VPN, Mail, Calendar and Pass for $6.49 a month on the first-year offer, and Proton Family covers up to 6 users with 3 TB. There are apps for Windows, macOS, iOS and Android, a web app and a CLI. The limits are capacity and renewal pricing: personal plans stop at 3 TB, and every first-year discount steps up at renewal, so budget for the full price.
