So, apparently you can easily get a Google account without telling Google your phone number if you have either an iPhone or a phone running Android 11:

... but the web interface definitely does not let me, and on my LineageOS phone (with microG), the option definitely does not exist. Seems like they only allow that if they can already get your stuff in other ways....
In related news: I'm still trying to figure out a privacy-friendly way to have a shared calendar online which can be edited by multiple people.
(in my case: for a shared practice space. So everyone can enter when they want to use it, and see when someone else is planning to do so.) -- any ideas?
Most CalDAV providers don't seem to offer that without either making it public or everyone requiring a (often paid...) account, including the provider I already pay for :(
@Mr_Teatime You can use OwnCloud/NextCloud Calendar for this - assuming you'd create a separate account for the calendar and share the credentials in the group.
@FailForward
Actually ... yes, that sounds pretty straightforward. Separate accounts for people might be better but it's a pretty small group, and we trust each other with more than a calendar, so it should be fine.
The follow-up question, being one of those weird people who operate no nextcloud server -- where to host this? I could buy a mailbox.org or posteo account for 1€/month, and not use any of the features except for the calendar, I guess...
@Mr_Teatime
I have to find out what the system requirements are for current versions of own-/nextcloud, but I have been running one for years on a RPi2 (at home).
If you don't want to do it yourself, https://nextcloud.com/providers/ could be a starting point.
@Mr_Teatime I really don't know. You need to ask "at freemo at qoto.org" about this.
