Proton has spent over five years building out its privacy-focused alternative systems to Google’s popular productivity apps, and it’s now ready with its own spreadsheet software. Proton Sheets is designed to compete with Google Sheets and Microsoft Excel for your data management needs.

Sheets is end-to-end encrypted by default, meaning even the brand itself can’t access your data. Proton is selling this as a business-first tool for those who want to keep their work data secure, but it’ll also work for customers who want to build their own personal spreadsheets.

It includes tools to build charts and graphs, formulas for fast math equations, and the ability to import and export different file types, including CSV and XLS.

You can share each spreadsheet with other Proton users, and you’ve got full control over sharing to either remove existing collaborators or expand access further.

Proton Drive’s Head of Product, Avant Vijay Singh, said, “The reality today is that most spreadsheet tools come from Big Tech giants whose entire business models are built on exploiting user data. Now, with AI woven deeply into these platforms, the risks have escalated exponentially.”

“Every keystroke, every formula you enter can feed into their AI training pipelines. This is an unacceptable trade-off. Users deserve a future free from hidden surveillance and invasive data mining.”

Sheets is free as long as you have a Proton Drive account. The brand’s free service offers 5GB of storage, plus there are paid-for options for up to 3TB of space.

Proton claims its service is ready to rival Google’s full suite of productivity tools with its end-to-end encrypted alternatives. Sheets joins Proton’s Calendar, Docs, Drive, Mail, and VPN services. The brand also offers PCMag’s pick for the best free password manager with Proton Pass.
