Proton Drive vs. Proton Calendar

Proton Drive is a secure cloud storage and collaboration platform built for professionals who manage sensitive data. Whether you’re sharing internal documents, legal contracts, or client files, Proton Drive keeps your data private — by default. Files are encrypted on your device before upload, and only you and your collaborators can access them. Even Proton can’t read your files. You can set passwords, add expiration dates, or revoke access instantly — so you’re always in control. Each user gets 1 TB of storage, with the flexibility to add more as your team or projects grow. Designed and hosted in Switzerland, Proton Drive is developed by the team behind Proton Mail and Proton VPN — trusted by over 100 million users worldwide. We’re independent, open source, and committed to keeping your data safe from surveillance and vendor lock-in. Proton Drive helps you stay compliant, with support for: - GDPR, HIPAA, ISO 27001, NIS2, and DORA - Verified SOC 2 Type II audits - No complex setup. No third-party tools required. Built for security teams, law firms, healthcare providers, consultancies, and privacy-conscious organizations of all sizes.

Proton Calendar acts as a detailed log of your daily activities while placing a high emphasis on your privacy. It provides automatic end-to-end encryption to keep all of your scheduled events secure. Moreover, events that are shared by users of different calendars benefit from zero-knowledge encryption, ensuring that sensitive information like titles, descriptions, locations, and guest lists remain private, protecting it from even Proton itself. This unique service enables you to manage your appointments effectively while also preserving your personal data. Created by the team behind Proton Mail, the world's largest encrypted email service, Proton Calendar has garnered a user base of over 50 million, which includes various well-known organizations.

With its innovative features, Proton Calendar not only helps you stay organized but also reinforces the importance of data privacy in our digital age.
