Building an encrypted calendar is at the top of our to-do list right now as we desperately need a solution to schedule and share calendar entries securely ourselves. However, first, we have to finish the new client to push it our of beta and update the Tutanota Android and iOS apps so that you can use your encrypted mailbox with very good speeds and many more features on all your devices. Once we are done with that, we will build the encrypted calendar.
Thank you very much for your continuous support.Hauptstadtkind commented
I totally agree to ToxicJ. Focus on email and address book first. There is still a lot to do. Calendar is a nice feature but a very big thing. I just wanna mention time zones, sharing options, import of/subsciption to 3rd party calendars, team calendars, DAV etc. Use your little manpower for other things.
