Features

Proton Calendar features: What can you do with it?

Each feature is meticulously crafted to offer you not just a scheduling tool, but a secure haven for your plans and appointments.

From end-to-end encryption that ensures your events remain your own, to seamless cross-device synchronization for on-the-go access—Proton Calendar’s features are designed to redefine your expectations from a calendar app.

Cross-Device Synchronization

Proton calendar devices

Proton Calendar ensures that your schedule is consistent across all your devices. Whether you’re using a web browser, Android phone, or iOS device, your calendar entries are automatically updated.

This eliminates the need to manually sync your events, providing a hassle-free experience.

Integration with Proton Mail

This feature allows for a more streamlined management of your schedule and email. If you receive an email invitation for an event, you can directly add it to your Proton Calendar without leaving your ProtonMail inbox.

This is particularly useful for quickly adding business meetings, flight schedules, or concert tickets that you receive via email.

Multiple Views

Proton calendar views

To help you manage your time more effectively, Proton Calendar offers various viewing options. You can choose to see your events in a daily view for detailed planning, a weekly view for a broader outlook, or a monthly view to get a high-level overview of your commitments.

Recurring Events

For events that happen regularly, like weekly meetings or monthly bill payments, the calendar allows you to set them up as recurring events. You can customize the frequency of these events to be daily, weekly, monthly, or even set up a custom recurrence pattern.

Customizable Reminders

Proton calendar custom reminders

You can set up multiple reminders for each event to ensure you never miss anything important. These reminders can be in the form of in-app notifications or email alerts. The flexibility in setting reminders allows you to choose what works best for you.

Personalization

Proton Calendar offers various themes to suit your aesthetic preferences. Whether you prefer a dark mode for better visibility in low light or a high-contrast mode for readability, you can customize the calendar’s appearance to fit your needs.

End-to-End Encryption

Security is a major focus of Proton Calendar. All your events are encrypted on your device before they are uploaded to the server. This means that nobody, not even Proton, can access your event details unless you give them permission.

Ad-Free Experience

Unlike many other free calendar services that rely on ads for revenue, Proton Calendar offers an ad-free experience. This ensures that your scheduling is not only private but also uninterrupted by distracting advertisements.

Controlled Access

You have the ability to control who can see your calendar and to what extent. You can grant full access, which allows someone to see all event details, or limited access, which only shows when you are available. This is useful for both personal and professional scheduling.

Shared Calendars

Proton calendar share

This feature allows you to share your calendar with others. You can generate a link to your calendar and share it with family, friends, or colleagues. You have the option to show either your full calendar or just your availability, providing flexibility in how you share your time.

Subscription to Other Calendars

Proton calendar everyone

You can also subscribe to calendars from other services. This is particularly useful for families or work teams who may be using different calendar platforms but still need to coordinate schedules.

Contact Management

The Contacts widget in Proton Calendar allows you to manage your contacts without leaving the calendar interface. You can add new contacts, remove outdated ones, merge duplicate entries, and even import a list of contacts. This feature also allows you to directly add these contacts to any event, making the process of sending invites more efficient.
