No More Doodle extension by Benjamin Piwowarski

No More Doodle fills in scheduling polls for you, using the events already in your calendar.

Open a poll, and the extension lays your calendar side by side with the poll's time slots: a calendar view on a shared time axis, and a list view spelling out exactly which events clash with each slot. Every slot gets a proposed answer, you adjust anything you disagree with, and one click fills the whole form.

Supported scheduling sites:

• Doodle (doodle.com)
• Evento (evento.renater.fr)
• Framadate (framadate.org)
• Timeful (timeful.app)
• Rallly (app.rallly.co)

You choose which calendars are consulted, and what each one means: a calendar can mark a slot as unavailable, as "if need be", or be ignored entirely. The most restrictive answer among the events overlapping a slot wins.

Calendars come from two places, and you can use either or both:

• macOS calendars. Whatever the Calendar app already syncs - iCloud, Exchange, Google and the rest - read locally through a small native bridge that talks to the EventKit framework. The bridge is installed separately; see the project homepage for the download.
• CalDAV accounts. Any server that speaks CalDAV: Nextcloud, Baikal, Radicale, iCloud, Fastmail and others. Add one from the extension's options page, which tells you where your provider issues app-specific passwords and checks the connection before you rely on it. The password is stored on your own computer and never in browser sync.

Nothing is sent anywhere except to your own CalDAV server, if you configure one. There is no account to create and no service in the middle.
