Proton Sheets joins the company’s productivity suite

The latest addition to Proton’s workplace suite is a spreadsheet tool called Proton Sheets. It will offer real-time collaboration, and users can control who has access to view and edit files. Proton Sheets can also be accessed on any device, including mobile ones. It supports importing CSV and XLS files, and the spreadsheets also support commonly used formulas for calculations.

A big part of Proton’s pitch is privacy, promising that users’ information won’t be used for training AI. The company also protects user data with end-to-end encryption by default; the press release pointedly notes that products like Google Sheets and Microsoft Excel don’t do the same.

The Sheets app will be a part of Proton Drive, which already includes a Docs platform with several features similar to those offered by other productivity tools from big tech brands. Proton also offers a VPN and a Mail app.
