Calendars
Create as many calendars as you like – one for work, one for the family, one for the club. Events you add on your phone show up on your computer and vice versa.

What can you use it for?
CalDAV and CardDAV are open standards that most calendar and contact programs understand. Your data lives in one place, and all your devices keep themselves up to date.
Tasks
To-do lists with due dates, priorities and subtasks. Tick it off on your phone, and it is done on your computer too.
Contacts
Address books with names, phone numbers, addresses and birthdays, so you do not lose them when you change phones.
Notes
Notes are stored on the server just like events and tasks. Use my app DavNotes on Android or WebNotes in the browser.
Getting started
- Create an accountAll you need is an email address. You will get an email with a link to click to confirm.
- Create your calendarsLog in to the Radicale web interface and create … ta-da … a calendar. Or a to-do list, an address book or a note collection. Many apps (e.g. DAVx⁵ and iPhone) can also create calendars themselves.
- Add the account in your programEnter the server address, your email as username and your password. Then pick the calendars and lists you want to use.
- Server
caldav.rpix.dk
If your program cannot find your calendars, use the full address:https://caldav.rpix.dk/dav/- Username

Your account, your data
- Free, no ads and no tracking.
- The server is in Denmark. Passwords are only stored as encrypted hashes.
- If you forget your password, you can get a new one. You can delete your account and all your data whenever you like.
- There is a limited number of places, and no guarantee of uptime or backup. Always keep your own copy of what matters.
- Accounts not used for 30 days are deleted automatically. You get an email first. A program syncing counts as use.

Behind the service is Radicale, a small open source CalDAV and CardDAV server, and a small account portal I wrote myself.
