Mark the date! The ProtonCalendar beta is here

illustration of ProtonCalendar

A calendar is more than just a tool. It’s a record of the moments that make up your life — your big meetings, your gatherings with friends, and children’s birthdays. For the longest time, to easily organize these events, you had to let large corporations monitor these special moments. These companies snoop on your calendar and use that information to inform their advertising.

ProtonCalendar is the first fully encrypted calendar app. You can use it to keep track of your plans and appointments while keeping your data private. 

ProtonCalendar uses end-to-end encryption to keep all your events’ sensitive information private and secure. The event title, description, location, and participants for every event are encrypted on your device before they reach our servers, so that no third party (including ProtonMail) can see the details of your events. Only you will know your plans.

If you are a ProtonMail or ProtonVPN user with a paid plan, you can start using the ProtonCalendar beta right now. Simply log in to your ProtonMail account using the ProtonMail Version 4.0 beta, and you will see ProtonCalendar on the sidebar:

If you don’t have a paid ProtonMail account yet, you can sign up here:

If you don’t see the Calendar icon (below) in the left menu, you might need to refresh the page.

ProtonCalendar takes Proton into the future

It’s no secret that we’re creating privacy-focused alternatives to the online services you use every day. ProtonCalendar is the next step in this process. Our calendar takes a comprehensive approach to user data security. No other calendar keeps as much data private as ProtonCalendar. As our thorough security model demonstrates, we worked hard to ensure that you have all the convenience you need from a calendar app along with the security and privacy you expect from Proton.

With ProtonCalendar, you can now quickly arrange your life and plan your events in a convenient, secure way. It uses the same end-to-end encryption that ProtonMail does, ensuring that no one, not even ProtonMail, can access your schedule except you.

Our calendar stops private companies from spying on your schedule. For our users with heightened security needs, ProtonCalendar will prevent authoritarian regimes from seeing who you are meeting with and what you are doing. It does this by keeping the details of all your events encrypted while they are stored on our servers. Even in the unlikely event of a breach, your agenda will remain secure.

Currently, you can use the ProtonCalendar beta to manage up to 10 calendars. You can create and delete events, set reminders, and schedule, edit, or delete events that repeat every day, week, month, or on custom days.

ProtonCalendar is just the latest project in our mission to create a more private Internet. A calendar app has been one of our most requested products — pairing a secure calendar with a private inbox dramatically increases the utility of both. And soon, you will be able to privately save and share documents to the cloud with ProtonDrive. Our mission is to create an Internet that serves you and doesn’t require you to hand over your personal data to governments or corporations.

Looking ahead

The current iteration of ProtonCalendar is an early beta. There will be substantial developments between now and when the project is publicly released. Over the course of the beta, additional features will be added such as the ability to share your calendar with other ProtonMail users and send event invites to anyone, even non-ProtonMail users. It will also make scheduling as easy as a single click by letting you sync events in your ProtonMail inbox with ProtonCalendar.

While ProtonCalendar is only available in the web version of ProtonMail for now, we will also be bringing ProtonCalendar to iOS and Android with dedicated mobile apps in 2020.

While we are excited to release the ProtonCalendar beta today to get initial feedback from the community, we realize there is still work to be done. We look forward to receiving and incorporating your input so that ProtonCalendar can meet all of your calendar needs.

We believe everyone has the right to plan dinner with friends without announcing to Google who will attend. For that reason, once ProtonCalendar is publicly released, a basic version will be available to all ProtonMail users (including Free users) while paid Proton users will benefit from additional functionality.

Your feedback matters

Our community has always been one of our greatest strengths, so we are again turning to you for help. Your feedback will greatly assist us in making improvements to ProtonCalendar, optimizing its design and giving you the private and secure calendar app you want.

During the beta, you can reach us with any feedback on ProtonCalendar via our bug report feature inside the web app.

You can also follow ProtonCalendar development via a dedicated ProtonCalendar Twitter account and the new ProtonCalendar subreddit on Reddit

Stay organized and protect your schedule from being spied on with ProtonCalendar.

Best Regards,
The Proton Team

  • Hi, excellent product’s iteration Richie and all team from Proton. At this moment the unique way to access my calendar is from web interface, ok? I can’t integrate the calendar with native calendar iOS app or others apps, like Fantastical on iOS, its correct?
    These assumptions call one second question. In the future we can use Fantastical app or at least native iOS app to manage calendar and appointments? These are important points to start the final migration from GHell, but still using Fantastical that is a great app with a full integration on xOS ecosystem (iOS, watchOS, macOS).

    Tks and a happy, successful and prosperous 2020 for you and everyone from Proton team.

  • You should open your beta to all protonmail first beta users. It’s kind of a pain to use gcal and protonmail, and paying for the calendar defeats the purpose of using protonmail.

    Reply
    • Since we don’t monetize our users, we support our service through subscriptions, and one of the perks of a paid account is early access to new products and features. Once ProtonCalendar is out of beta, it will be available to users with Free plans as well.

  • I am guessing there is no import process for the new pCal from something like gCal right now? Unless the import/export app for email works on this?

    Just looking for an easy way to test by importing my gCal events and making sure notifications trigger from both calendars.

    Thanks, it looks good so far….can’t wait for the pDrive to follow!

    • At this stage, you can’t import or export your calendar or events. We’re currently working on this feature, and it will be available in future releases.

  • Regarding feedback. I don’t want to point out the obvious stuff you’re already working on.

    Should we submit bug reports for really obvious features like: Repeating end dates, More sophisticated repeating schedules, More view options, and the like?

    Is there a list of planned features anywhere?

  • The Proton Calendar beta is very impressive!

    One thing I would suggest you emphasize to users is that the Calendar works best if your browser is set to full screen, or close to full screen. If the browser window is too small, not all features of the Calendar, such as the month view, display properly. .

    It took me awhile to figure that out.

  • With regards to the ‘reminders’, I assume once native apps are released, reminders will be provided via push notifications? But until then, whilst it’s web-only, will the reminders be in the form of email?

  • Great progress! Two questions:

    1) will there be somehing like ProtonCalendar Bridge? So I can use it wih my favourite client like Thunderbird?
    2) will be ProtonCalendar recognized in Android as one of the local (synced) Calendar to be shared in other apps? (like TickTick)

    Reply
    • Thank you!

      1. No, this is not planned at the moment.
      2. We might be able to in the future, but this would require a public calendar (which is planned but not a top priority).

  • Indeed looks very nice but will not be of much use until I can sync it to my mobile (Android) device and I mean calendar widget – not inside some app that you need to open first. A bit surprising the launch happened as browser only but of course it is still beta so I assume full roll-out will be with mobile+web as only a very limited group of people use web as the only interface?

    Reply
  • Very nice job indeed! Do you have any plans of developing a pc desktop version that could be synchronized with the mobile app version?

    Keep up the great work!

  • El día que la app para iOS admita los correos agrupados por hilos ese día dejaré de usar las cuentas de la empresa con otros servicios y pasaré a usarlas en protonmail como ya hago con todas las cuentas personales que tengo.

    El calendario es otra de las funciones que determinará la migración total a protonmail.

    Gracias por un estupendo trabajo

  • It looks really neat and rather nice!

    One thing that strikes me (after a fairly brief look) is that I can’t find a section for adding notes; that is quite important for me.
    Also is it possible to add contacts for meetings?

    • When you create an event you should be able to add a description. Is this what you mean?

      As for inviting/adding other people to an event, this feature is under development and will be released soon.

  • Good job guys! Love it. Will you work on a task manager like feature integrated in the calendar as well? That would make it just the thing.
    Keep moving!

  • Great work so far. As others have mentioned, the need for more Repeatability/Frequency options are needed.

    Examples: daily repeatability, custom start and end dates, repeat for x number of times, ability to delete 1 entry in a series of repeating entries, ability to modify only 1 entry in a series of repeating entries.

    These are just a few of the things I am noticing while using the calendar. Of course the ability to import your Apple or Gmail calendar would be a great feature to have for those of us that have rather busy calendars.

    Again, great work so far. Very clean user interface and easy to use.

    Reply
  • I can’t seem to be able to invite anyone / specify meeting participants. Am I missing something obvious, or that part is not implemented yet? Without the ability to add others it’s not very useful for meetings.

    Reply
  • this is a great step in making Proton an all-in-one solution. I’m hoping for native Android and iOS apps though that it will be able to integrate with other apps seamlessly so I can have an ‘all in one’ agenda view across both my Proton and work calendars (eg using one of the many 3rd party widgets). If the calendar data is totally isolated and secured it will be a barrier to using it productively…

    I have desperately been looking for a nice calendar app. I love Protonmail and ProtonVPN and recommend them to nearly everyone that I meet. ProtonCalendar makes me so happy! I have been waiting for this for a long time! Even better when ProtonCalendar comes as a native Android app.

    I can make a suggestion that you provide a “Notes” section to calendar events. I see that there is already a “Description” section, but the character limit is pretty low. It would be nice to have a separate section for storing information about the event, i.e. directions on how to get to a venue, instructions on what to do on arrival, etc. I find myself often needing this feature.

    I cannot wait to see the future iterations of this app. I am a very satisfied customer, and am very pleased with the work you guys are doing for us!

  • A. I have never found a calendar application that supports the following need which would greatly expedite repetitive data entry. But, I have heard of this need verbalized. .
    A.1. Frequently, at least for me, there is basic scheduling information that needs to be entered for irregularly occurring events. .
    B. A review, I have made on numerous calendar programs, revealed that most calendar programs are the same in offerings. .
    C. Contacts for programs such as telephones, e-mail etc. have a data base component that can be copied and pasted. .
    C.1. Why do calendar programs not have a data base component that can be cut and pasted to specific irregular calendar date occurrences? Then all that is to be entered is the time components. This is a most vexing and time wasting exercise in using a calendar program. .
    D. The best alternative I use is to put the repetitive information on an index card one time and just update the irregularly occurring dates. .
    D.1. However, it does fulfill the need. If I were a programmer of moderate abilities, I would be making a lot of money on this added feature to a calendar program I would also develop. Hmmmmm….. . ; ,)

  • Hi, when are additional features such as calendar invites to other proton mail and non-protonmail users expected to be added?

    Reply
  • This is a great, but the make or brake feature I am looking for is to be able to share the calendar with my family. We always talk about having an efficient way of sharing calendar but I generally don’t trust the maps on the market. Since i have good experience of protonmail, a calendar by proton would be ideal if it only supports sharing. Looking at the calendar today, the most important thing that is not already there is sharing with other proton mail users (my spouse) so we can add, change, remove and see in real-time, preferably from our phones.
    Please please make this a priority!

    PS! Proton key locker would also be on my shopping list the day it arrives. I am hoping this is something already on the roadmap.

  • It’s now about 6 months since Protonmail v4.0.0 went into Beta. It seems like a long time between a Beta and Production release, and there is no calendar at all on smartphones. Just to be clear, it is hard to use a calendar in any kind of serious manner without app support Most of the calendar events are entered on the phone.

    Is there a target date (something more specific than ‘soon’) for the release of the calendar on smartphones and the production release of v4.0.0?
