Proton Launches Encrypted Spreadsheet App as Privacy-Focused Alternative to Google Sheets

Proton Sheets Brings End-to-End Encryption to Spreadsheets

Proton has launched Proton Sheets, expanding its privacy-focused productivity suite with an encrypted spreadsheet application. The new tool aims to compete with established platforms like Google Sheets and Microsoft Excel while prioritizing user privacy through comprehensive encryption.

Key Features and Privacy Protection

Unlike traditional spreadsheet applications, Proton Sheets encrypts all user data by default, including filenames. This end-to-end encryption ensures that spreadsheet content remains private and inaccessible to anyone except authorized users.

The application supports real-time collaboration, allowing multiple users to work on the same document simultaneously. Users maintain granular control over access permissions, determining who can view or edit their spreadsheets.

Compatibility and Access

Proton Sheets is designed as a web application accessible across multiple platforms, including desktop and mobile devices. This cross-device compatibility ensures users can work on their spreadsheets regardless of their location or preferred device.

The platform supports importing existing files in CSV and Excel formats, making it easier for users to transition from other spreadsheet applications without losing their existing data.

Why It Matters for Consumers

Proton Sheets addresses growing concerns about data privacy in cloud-based productivity tools. While services like Google Sheets offer convenience, they have faced scrutiny over data collection practices. Proton's approach provides users with a familiar spreadsheet experience while ensuring their sensitive financial, business, or personal data remains encrypted and private.

The addition of Proton Sheets completes Proton's suite of privacy-focused productivity tools, joining existing services in the company's ecosystem. For users already invested in Proton's privacy-first philosophy, the new spreadsheet tool offers a cohesive solution for secure document collaboration and data management.
