Proton Calendar: Secure Events APP Review

Proton Calendar is an easy-to-use planner and a time-management tool that keeps your schedule private. This app offers a range of features for users who prioritize privacy while still requiring efficient scheduling capabilities.

The calendar syncs automatically across all devices and browsers, allowing you to create recurring events and manage multiple calendars with ease. Additionally, it provides options for appointment scheduling in various time zones, a home screen widget to view your agenda at a glance, and several customization options including dark and light modes.

What sets Proton Calendar apart is its staunch commitment to user privacy. Operating from Switzerland, it guarantees no ads or trackers, and all your information is protected under robust privacy laws. The app uses end-to-end encryption to ensure that only you and your event participants can access your calendar data.

However, while Proton Calendar aims to provide a secure experience, it has been noted that certain features need improvement. Users have expressed desires for added functionalities such as a search option and better integration with various tools and apps. Overall, Proton Calendar is a solid choice for privacy-conscious individuals looking for a reliable scheduling app.

I love the design but honestly, it's 2025 and you can't: 1) add events while offline, 2) search for any calendar events, 3) click on the address of the event and open it in a maps app, 4) add holiday calendars for some countries, including member states of the EU.

Proton Calendar is a great and safe alternative to Google Calendar. However, loading the events is sometimes a bit slow and could be improved. Furthermore, it would be great to have the option to copy events just like on the desktop web app.

Version: 2.30.0

Developer Response

Hi Martin. Thank you for the review and feedback! We'll note your +1 for the ability to copy events in the app. Try clearing the app's data from your device's settings → "Apps" → "Proton Calendar" → "Storage" → "Clear local data/cache" to see if that helps. If the issue persists, submit a bug report via the "Report a problem" feature in the app.

I like Proton overall, but the calendar widget is terrible - doesn't refresh on its own. If I want the whole thing to refresh, I have to remove it and replace it.
