Is Mufka free?
Yes. Mufka is free and open source under the MIT licence. There is no account, subscription or paid tier.
Which Macs does it run on?
macOS 12 Monterey or later, on Apple silicon and Intel — one download for both.
Why does macOS warn me the first time I open it?
Mufka is not notarized by Apple yet, so macOS asks once. Open System Settings → Privacy & Security and click Open Anyway next to the message about Mufka. You only do this once.
Can I use my existing Obsidian vault?
Yes. Choose any folder as your notes folder — Mufka reads and writes plain Markdown, follows Obsidian’s daily‑note and attachment settings, and adds nothing on its own.
How do the calendars connect, and what can Mufka see?
In Settings, Connect opens Microsoft’s or Google’s own sign‑in page. Mufka asks only to read your calendars (Calendars.Read / calendar.readonly). It shows your events in the Planner and on Home and never creates, changes or deletes anything.
Where is my data, and how do I delete it?
Everything lives on your Mac: notes in your notes folder, plans and settings in ~/Library/Application Support/Mufka. Disconnect a calendar in Settings to remove its sign‑in; delete that folder to remove everything. See the privacy policy.
