https://www.privacytools.io/ is also a good resource.
A nice Google Calendar replacement is Fruux - hosted in Germany, multidevice support.
OpenStreetMap is a nice idea but it is not a GMaps replacer by any means. It is not robust or cross-platform.
For simuldub dates from the summer keep an eye on funimations summer blog since they are continuously announcing the release dates. For physical releases of shows here’s a link to a calendar that’s consistently being updated by one of the users on this sub I think.

Welcome to the NHK is an older 2000’s show about a shut in who is convinced he’s part of a conspiracy by a Japanese company to make everyone basically shut ins. It’s an amazing show that’s really about an up hill battle with depression and loneliness with a great supporting cast of characters who all have their own problems to solve. Very depressing dark humor. But all around a deep show.
Same here, https://privacytools.io practically lists every type of tool except a private web calendar.
The one I know of is Thunderbird's built-in one, but i think it's only local? (unless you know your way around syncing it to a server)
And just now I found one by searching this subreddit, https://fruux.com/ but i haven't tried it.
sabre/katana
focuses on contacts, calendars, task lists and files. ownCloud is a bigger tool which includes different features. ownCloud is based on sabre/dav
though, just like sabre/katana
but sabre/katana
is based on a more recent version of sabre/dav
which includes better performances, more features, better security etc.
sabre/katana
does not aim to be a huge tool. We would like to respect the Unix philosophy: Do one thing and do it well. Contacts, calendars & co. are part of the DAV technology family. This is the one thing. The border is difficult to draw though (file permissions etc.) but we are planning to introduce extensions/plugins to extend sabre/katana
features.
Also, from a basic point of view, sabre/katana
is way lighter than ownCloud :-]. Oh and I forgot to mention that this is just a server, not a client. We are going to develop specific standalone clients in the future (do one thing…).
Finally, sabre/katana
has an administration interface, which we are going to “extract” in order to be used on top of any DAV servers. Like the clients we are preparing, they will be server agnostic. This is the fruux philosophy actually: Push the whole industry, not just our own business :-).
Google being able to see your contacts depends on a lot of things . If you use etesync (or other carddav server of some sort) to sync/store your contacts, then google no longer stores them and I'm not sure how google would see them. I'm assuming you'd delete all contacts out of google contacts once you were happy with their new location and that you are not using a gmail.
Maybe you could describe what you're trying to do? How many devices to you want to sync contacts across?
Etesync is unusual in that it goes the extra step to end-to-end encrypt your contact data on their servers , but it adds some complication to the setup and you may not need that.
Your original question was about how important it is to encrypt contacts and I think it depends. If you just want to keep your data out of Google's data collection hands, then there are other options to store/sync contacts and calendar data (but most are not E2EE). There aren't a lot of options that I've found as most people don't want to pay for this when they can get it free from Google or Apple. Fruux is another one I've seen but it's not free and is really designed for teams.
Thanks! I just found https://fruux.com/ (which is based on Baikal) and I'm playing with it. Looks quite nice but I'm missing a couple of things (mail notification, setting notifications at desired times) but apart from that the UI is just great :-)
Protonmail is going to be releasing a calendar later this summer, I believe. Until then, I use fruux.com calendars, and use DavDroid to sync them to my phone (with etar for Android calendar).
Checking it out now.
Edit: I've looked into it. Seems like a great option. I was going to ask if they're secure but then I read this on their website...
"Always secure
Your data is always encrypted and securely backed up for you - on servers in Germany."
I'm currently using Fruux and it's working pretty okay. According to their Security & Reliability page, they encrypt "All your personal data" at rest, which hopefully includes your calendar entries.
The web interface isn't the best, but it works. I mostly use it with another calendar app on my Android, and that works very well.
Edit:
They also offer contact sync, which is good if you're out to replace google.
What I forgot to mention, which worries me somewhat and is one of few things that keep me from becoming a paid subscriber, is the lack of public announcements. The previous blog, and Facebook, post is ~1 year old. Paging /u/fruux for comment.
I think you can use any calDAV server and then grab a syncing app from f-droid. Owncloud uses sabre/dav (http://sabre.io/), so if you're already using owncloud, it may just be a matter of turning on that module...else you could set up a separate webDAV server.
For folks who might not want to hassle with rolling their own, I've been using Fruux (https://fruux.com/) for a few months and been very happy with it. I know this doesn't help the OP.
Edit: Just found sabre/katana, which looks like the DIY fruux: http://mnt.io/P/2015-07-13_sabre-katana_a_contact_calendar_task_list_and_file_server.html
