Support
Stuck, puzzled, or found a bug? Drop me an email — it reaches a real person (me). There's no crash reporting in the app, so a quick message genuinely helps me find things.
Getting started
Use the calendars you already have
Open Settings → Accounts and choose Connect Apple Calendar to bring in everything already on your Mac through Apple's EventKit: iCloud, Google, Exchange/Outlook, Yahoo, shared calendars and subscriptions. You can edit those events in Callllendar too. macOS will ask your permission for Calendar access the first time.
Connect a server directly (CalDAV)
To talk straight to a server, add a CalDAV account with its URL, your username, and a password. If your provider uses two-factor authentication you'll usually need an app-specific password rather than your normal login:
- iCloud: appleid.apple.com → Sign-In and Security → App-Specific Passwords.
- Fastmail: Settings → Privacy & Security → App Passwords.
- mailbox.org and Posteo: create an app password in your account's security settings.
Google doesn't allow app passwords for CalDAV, so this route won't work for a Google account. Set Google up in the Mac's Calendar app and use Connect Apple Calendar instead.
The password is stored in the Keychain on your device, never in plain text and never sent to me. You can also subscribe to a read-only calendar with a webcal:// link, or import an .ics file by dragging it in.
Works with: anything in Apple Calendar on your device, which covers iCloud, Google, Exchange/Outlook, Yahoo and most other accounts. Directly over CalDAV: iCloud, Fastmail, mailbox.org, Posteo and any standard CalDAV server.
Doesn't work with: Google or Microsoft accounts added directly as CalDAV. Google needs an OAuth sign-in that Callllendar doesn't support, so an app password won't work, and there's no direct support for Exchange ActiveSync, EWS or Microsoft Graph. For Google, Exchange, Outlook or Office 365, go through Apple Calendar.
An iPhone and iPad version is on the way. It connects through Apple Calendar on the device the same way.
Or keep it local
You don't need any account at all. A local "Personal" calendar is ready the moment you launch, stored only on your Mac, and it works fully offline.
Keyboard shortcuts
Callllendar is built to be driven from the keyboard. A few of the keys you'll use most:
- N new event · T jump to today · 1–6 switch views
- / search · ⌘K command palette · ? shows the full list inside the app
- S toggle the detail panel · ⌥⌘S toggle the calendar sidebar
- Select an event and press Delete to remove it. In the editor, Enter saves.
Siri & Shortcuts
Callllendar adds three actions to the Shortcuts app and Spotlight: New Event, Next Event, and Today's Agenda. The two "ask" actions answer out loud — no window needed.
Tip — invoking by voice. Because "Callllendar" sounds like "calendar," Siri may hear a generic calendar request. For reliable voice control, open Shortcuts, wrap a Callllendar action in a new shortcut, and give it a distinctive name (e.g. "My agenda"). Then just say "Hey Siri, My agenda."
Common questions
Does Callllendar send my data anywhere?
No. Events stay on your Mac, or sync directly between your Mac and your own Apple/CalDAV server. There's no Callllendar server in the middle, and the app sends no telemetry. See the Privacy Policy.
Where are my CalDAV passwords stored?
Only in your Mac's Keychain — system-encrypted at rest, never written in plain text, never transmitted to me.
Why does a meeting link sometimes warn me?
Links in event invitations are checked against public threat lists (phishing/malware) locally, and trackers are stripped, before anything opens. You can always choose to open anyway.
Does it work without internet?
Yes. Local calendars are fully offline; Apple and CalDAV calendars sync whenever you're online.
How do updates work?
Through the Mac App Store, like any other app — it'll let you know when a new version is ready. There's no separate updater inside the app.
Is it really a one-time purchase?
Yes. One price, no subscription, no tiers, no upsells. You buy the app once on the Mac App Store and own it.
Get in touch
Setup help, bug reports, privacy questions — anything. I read every message. No ticket queue, no autoresponder, no form-processing middleman: it's just direct email to me. (Fittingly — Callllendar's whole point is that nobody sits in the middle of your schedule.)
Email me proton.me.bobcat320@passmail.netPlease include your macOS version and, if it's about a specific event, what you were doing when it happened. A screenshot often helps — just attach it to your email.
Privacy
