Proton Calendar
Proton Calendar is a privacy-focused calendar service for scheduling events, managing recurring plans, and handling invitations across Proton apps.
What is Proton Calendar?
Proton Calendar is a calendar app and web service for organizing events, reminders, recurring schedules, and invitations with a strong privacy focus. It is designed for people who want everyday calendar features such as day, week, and month views, event notifications, shared planning, and imports from other calendar services while keeping schedule details within the Proton ecosystem. On Mac, calendar access is commonly provided through the Proton Mail desktop app or the Proton web app in a browser, rather than a separate standalone Mac app. Users often choose it to manage personal schedules, coordinate meetings, send invitations, and keep mail and calendar activity connected in one account. It fits well for individuals, families, and work users who already use Proton services and want a calendar that syncs across desktop, web, and mobile devices.

Safety overview
Status: Mostly safe
This is legitimate calendar software from Proton’s service ecosystem. Access to notifications, calendar data, and account sign-in is normal for its purpose. If you use it through the desktop or web experience on Mac, your events and invitations may sync with your Proton account across devices, so use a strong password and review account security settings if your schedule contains sensitive information.
Recommendation: Keep Proton Calendar if you use Proton for scheduling, invitations, or connected mail and calendar workflows. Remove it only if you no longer use Proton services, understanding that uninstalling the related app or signing out will stop local access to your synced calendar on this Mac.
