Proton Calendar for Web

Overview

Proton Calendar is a privacy-focused mobile calendar developed by Proton Technologies, the team behind ProtonMail. It’s designed for tracking meetings, events, and personal appointments while keeping your schedule private. The app is currently in beta and is available only to paying ProtonMail and ProtonVPN subscribers.

Privacy and data protections

Proton Calendar applies strong encryption to your calendar entries, meaning only you can read the contents of your events. Proton’s developers cannot view your schedules, and the service is delivered without ads or third-party trackers. These protections mirror the privacy features found in ProtonMail and ProtonVPN.

Main capabilities

• Create, modify, view, and remove events with a straightforward interface.
• Sync your calendar data across multiple devices so updates made on one device appear everywhere.
• Manage up to ten separate calendars to keep work, family, and personal plans distinct.
• Schedule events in different time zones, useful when traveling or coordinating with people abroad.
• Set repeating events and add several reminders for each appointment.
• Import existing events from other calendar services to avoid re-entering everything manually.
• Add emojis to event titles or descriptions for quick visual cues.

Limitations and access

Proton Calendar is still under beta testing, so functionality and availability may change. At present, access is restricted to users with paid ProtonMail or ProtonVPN subscriptions; there is no public free tier for the calendar app yet.

Final assessment

If you rely on a calendar app and place a high value on privacy, Proton Calendar is worth considering. It provides the essential tools for organizing schedules, separates different areas of your life into distinct calendars, and prioritizes strong data protection.
