Proton Launches Encrypted Spreadsheet Tool to Challenge Tech Giants on Privacy

Privacy-focused service provider Proton has officially launched Proton Sheets, an encrypted spreadsheet tool positioned as a secure alternative to Microsoft Excel and Google Sheets.

The move marks another step in the company’s mission to provide privacy-respecting alternatives to mainstream productivity tools.

Addressing Critical Privacy Concerns

Modern business infrastructure relies heavily on spreadsheets, yet data security vulnerabilities remain a significant concern. Proton emphasizes that industries worldwide urgently need solutions that can effectively defend against surveillance, tracking, and unauthorized AI training on sensitive data.

The company specifically cited Google’s own support documentation to highlight these risks. Google has warned users against entering confidential information into Google Sheets, noting that such data may be accessed by human reviewers or used to train its AI model, Gemini. Proton Sheets aims to address this fundamental privacy gap.

Competitive Features with Enhanced Security

Proton Sheets is designed to meet industry standards in functionality while prioritizing user privacy. The tool supports most users’ daily needs, including real-time collaboration, formula calculations, data analysis, and chart creation.

The platform’s defining feature is its default end-to-end encryption, ensuring that only users themselves can access their spreadsheet content—neither Proton nor any third party can view the data. The service supports XLS and CSV file formats, allowing users to easily migrate existing documents to the encrypted platform.

Part of a Growing Privacy Ecosystem

Following Proton’s freemium strategy, Proton Sheets is available at no cost to all Proton Drive account holders. With the addition of Sheets, Proton has built a comprehensive service ecosystem that now includes Mail, Drive, Docs, Pass (password management), and VPN.

This expanding suite of tools offers users seeking greater privacy protection a viable path away from the ecosystems of tech giants like Microsoft and Google. As concerns about data privacy and AI training practices continue to grow, Proton’s integrated approach provides users with a complete alternative that doesn’t require sacrificing functionality for security.

The launch of Proton Sheets represents a significant milestone in the ongoing debate about digital privacy and corporate data practices, offering businesses and individuals a practical option for keeping their sensitive information truly private.
