Geneva-based Proton has expanded its secure productivity suite with the launch of Proton Sheets, a new spreadsheet application integrated with Proton Drive. The addition provides a privacy-focused alternative to established offerings like Microsoft Excel and Google Sheets, catering to a growing demand for data security in the digital workspace.
Proton announced the availability of Proton Sheets, positioning it as a secure-by-default tool designed to protect user data. Like other Proton services, the new tableur leverages end-to-end encryption to safeguard content.
According to the company, Proton Sheets does not collect or utilize user data for advertising or artificial intelligence model training.
Secure Collaboration and Familiar Features
Proton Sheets functions as a standard online spreadsheet tool, offering real-time collaboration features. Users can edit spreadsheets simultaneously, visualize data with charts, and perform calculations using integrated formulas. The application also supports importing and exporting CSV and XLS files, managing access permissions, and enabling remote collaboration across devices.
The interface is designed to be familiar to users transitioning from other spreadsheet programs. Sheets, like Proton’s other services (according to recent reports), is hosted in Switzerland and benefits from the country’s current data protection laws.
Proton Sheets joins Proton Mail, Proton Calendar, and Proton Docs in a suite of tools aimed at privacy-conscious users. The company specifically targets small organizations, NGOs, journalists, and professionals who need to manage sensitive information securely.
