Calendars

Calendars kept on Parahub and synced with the calendar app your phone or computer already has — iPhone and Mac, Android, Thunderbird. Share them with family, helpers and your bots, in full or as busy only. Nothing is ever public.

Connect a device

  1. 1Open Profile → Calendars and press «Connect a device». Calendars
  2. 2Name the device and copy its password. It is shown only once and Parahub keeps no copy. Each phone or computer gets its own, and you can revoke it at any time.
  3. 3Add the account in your calendar app, with your handle as the user name and that password. Your calendars and the ones shared with you appear by themselves.
iPhone and iPad
Settings → Apps → Calendar → Calendar Accounts → Add Account → Other → «Add CalDAV Account». Server: parahub.io.
Android
Install the free DAVx⁵ app (F-Droid), choose «Login with URL and user name» and enter the address shown in Parahub. The calendars then appear in the calendar app on the phone; Google Calendar shows them once you switch the account on in its Settings → Manage accounts.
Thunderbird
Calendar → New Calendar → On the Network, with your handle and the address shown in Parahub. Changes sync both ways.

Sharing

Open a calendar, press Share, choose the person and how much they see: read, read and write, or busy only.

An invitation, never a push
The calendar reaches the other person's devices only after they accept it in Parahub — nobody can put events on a stranger's phone. Your own other profiles and your bots get it at once.
Busy only
A separate copy the server keeps in step with yours: the same times and repeats, every title replaced by «Busy», and nothing else — no places, people, notes or reminders. Free and cancelled events are left out.
Your calendar stays yours
Someone with write access who deletes the shared calendar on their phone is refused — yours stays, and so does everyone else's access. They may rename or recolour it for themselves.
For your bots
A bot has no calendars of its own. Share one with it and issue it a password on the bot's page: it sees exactly what you shared, at the level you chose. Pausing the bot revokes that password too.

The «Parahub» calendar

Once you connect a first device, a calendar named «Parahub» appears next to yours: the events you organize or said you will attend («maybe» shows as tentative) and your bookings — as the renter, or for the things you rent out. Parahub keeps it in step when times change or something is cancelled. Devices can read it but not change it, and you can share it — busy only to a bot, for example.

Every published event also has an «Add to calendar» button: a file for any calendar app, no account needed. If you have both, the event shows once, not twice.

In your webmail

The calendar page of your mailbox shows the calendars of your main profile by itself — your own, the ones shared with you and the «Parahub» calendar, which appears there with your first event or booking even if no device is connected. It is for looking: events are added and changed on your devices, and a change shows up within a minute.

The webmail reads each calendar with a password that can only read, and your calendars do not tell other mailboxes when you are busy. One switch under Profile → Calendars → Webmail turns it off. Calendars of a pseudonym are never shown there.

Private, but not end-to-end encrypted

There are no public calendar links, and a calendar nobody shared with you looks exactly like one that does not exist. The events themselves are stored on this node's server, as with any calendar server, so the node's operator could technically read them. Busy only is cut on the server: the person it is shared with never receives the details.
