So incredibly grateful for this, you guys are the best! It's definitely a very good start, however I do agree with some points below that certain features are still lacking. But I have faith that this will be developed further to fully replace services like Calendly

I would love a native iframe/embed for this booking feature. I'm currently using an cal.com (cal.eu) embed on my personal page for booking appointments with me. If protons appointment scheduling had an embed, I'd switch over, which would be nice as then I could also use Proton Meets for the appointments.

In my opinion, this isn't a 100% replacement for the functionality offered by Calendly or TidyCal.

For the person making the booking, there's only a name and email address field. With Calendly and TidyCal, I have informative forms that my clients can fill out before booking. I'm missing address details (street, city, postal code, phone number) as well as a subject for the booking, ideally with a predefined selection that the client can choose. Furthermore, my main Proton email address is displayed below the organizer in the booking field. Since I use my own domain address, which is associated with my practice, I should be able to choose what is displayed, as I don't want my private Proton address to appear there. Ideally, I would prefer that no email address be displayed at all.

Besides a link to the booking page, an embed code for websites would also be great.

It would be nice if these things could be improved.

What about individual users? I'm a self-employed consultant and don't need a business plan, but would benefit from appointment scheduling, too.

Agree many times. For me, it is a decision-making factor: to stay with Proton or to find an alternative solution for both mail and calendar services, as they go hand in hand. This is the case when security ruins the business. I also need this functionality ASAP.

I need Calendly type functionality urgently as it saves me hours of time. When will this be available and can I join as Beta tester ?

how much do we have to pay to get this critical missing feature

I need this feature, too! It's crtitical for me as I won't use Google or MS services because of privacy!

I just needed this feature and had to result to sharing my calendars via ICS to google and the google calendar back to proton so i can use that feature with google calendar, which is an ugly workaround but it works

This would be great, although would need to plug into a pay system, and offer different options of events. I suggest cal.com / cal.eu as a guide their offer is overall very good.

Until then, please ensure we can use external solutions efficiently. (Ideas logged on ICS feed made real time to avoid overbookings and caldav).

Please please please put this at the front of the calendar roadmap! This is a critical need!

Agreed! This will be a gamechanger for me. I use google calendars to link my proton calendar to Calendly which defeats the purpose of switching over to proton. A complete alternative to Calendly would be amazing!

I wonder if this feature will be added with the new Proton Meet. That would be amazing!!!

This would be a game changer!! We absolutely need this. It would be the final thing that would make most of the people around me consider moving over to Proton as well.

Agreed - this would be a great feature for scheduling office hours.

For people in the field of health / counselling / coaching and dealing with customer from the diversity, having a secured way to propose booking of slots is key to protect citizens personal life. Proton trademark could be a way to provide confidence to user that their personal information is fully secured. This is a complement to the great function of Proton Meet to have an ecosystem where cirticial personal identifiable information is protected from being extracted by state or hackers.

I have just moved everything from Google Workspace before realising that no calendar booking apps integrate natively with Proton Calendar.
This is mission critical to my business and I might land up having to move away from Proton because this is not available.

This is a huge need and would make it seamless to switch from google.

Wish I could upvote this x1000, huge need for this!

Online scheduling is mainstream and table stakes for a lot of users. Delivering this capability is the only way to keep calendar data secure in Proton Calendar – without forgoing E2EE security. The only current alternative is to create and publish a read-only "Limited view" ICS link, which is too much compromise, and no option exists to write a scheduled event to a secure Proton Calendar. The only option is for a Proton Native and hosted scheduling service.

Please, please strongly consider prioritizing this! Life without it is very, very difficult.

I need either synchronization with my current booking tool (youcanbookme) or a similar service integrated in proton calendar. Would that be possible?
