What is Proton Calendar?

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. Furthermore, this calendar comes with a Proton Mail address, allowing you to send secure invitations for events, which significantly boosts your organizational abilities. You can also quickly add new appointments to your calendar straight from your Proton Mail inbox, making the process of scheduling even more efficient and user-friendly. With its innovative features, Proton Calendar not only helps you stay organized but also reinforces the importance of data privacy in our digital age.
