Proton now has an end-to-end encrypted spreadsheet app

Proton has introduced a new spreadsheet application, Proton Sheets, adding to its suite of privacy-focused productivity tools. This move aims to offer users a secure alternative to the offerings from Google and Microsoft, particularly in light of increasing concerns regarding data privacy and surveillance practices. The introduction of Proton Sheets is a direct response to the concerns around data harvesting by major tech firms. Proton Sheets offers end-to-end encryption, ensuring that only the user can access their data. It integrates with a Proton Drive account, which includes a free tier with 5GB of storage. The tool is compatible with web browsers and the Proton Drive app, supporting real-time collaboration, common formulas, and the import of CSV and XLS files. The launch of Proton Sheets, similar in design to Excel and Google Sheets, aims to provide an immediately familiar user interface. This is part of Proton's effort to offer a full suite of secure services, following the prior release of Proton Docs, a word processor. This expansion by Proton directly addresses the growing demand for digital privacy, offering a European alternative to data-intensive services.
