## What is dCal?

dCal is a local-first schedule keeper. Everything stays on your Mac and iPhone — no data is ever sent to the cloud.

■ Truly local — proven, not just promised
dCal has no network connectivity. macOS App Sandbox denies the app any network entitlement, so it cannot reach any server technically. Perfect for confidential meetings, sensitive client schedules, or anyone who values their privacy.

■ See four weeks at a glance
The signature 3–6 week grid view shows long-running projects as continuous lines, never broken at month boundaries — something Apple Calendar can't do.

■ Notes, not just events
Each day cell can hold unlimited rich text — meeting minutes, work logs, family notes. Bold, italic, underline, color formatting. Full-text search across all your notes.

■ Windows hyCalendar compatible
Opens .cal files from hyCalendar (Windows freeware) byte-for-byte unchanged. Edit on Mac, save, and the file remains identical.

■ Japanese holidays built-in
Including substitute holidays and citizens' holidays. Computed from the official rules; no online lookup required. Valid 1980–2099.

■ Fast search (⌘F)
Find any keyword across day notes and period event titles. Highlighted matches, sorted by date.

■ Jump to any date (⌘J)
Year scroller + 12-month grid. Two clicks to reach any past date.

■ Mac + iPhone — sync your way
Use iCloud Drive, Dropbox, Google Drive, OneDrive — your choice. dCal itself never talks to those services; it just reads the file your sync client provides.

■ Plain text forever
No proprietary binary. Your .cal file remains human-readable. Even without dCal in 20 years, your data lives on.

■ Native Apple experience
Modern macOS / iOS design language. Glass materials, rounded cards, system fonts, Dark Mode.

Designed for:
• Lawyers, accountants, tax advisors with confidentiality obligations
• Doctors, therapists, anyone handling sensitive personal data
• Executives managing private meetings
• Privacy-conscious users
• Existing Windows hyCalendar users moving to Apple
• Anyone frustrated by Apple Calendar's monthly cut-off

Principles:
• No account required, no subscription
• No analytics, no tracking
• One-time purchase
• Your data is your data


## Version history (last 2 releases)

### 1.0.1 — 2026-07-03

Version 1.0.1 polishes the UI in response to the very first round
of feedback after launch.
Improvements
• When you pick a month in the year/month popover, the calendar
  now opens with that month's first week at the top — so picking
  "October" actually puts you AT October from day 1. Mac and iPhone.
• On Mac, the right-arrow button in the year selector no longer
  hides off-screen.
• On Mac, the search panel now closes when you click outside it.
Fixes
• In English UI, the centred search placeholder no longer leaks
  the Japanese fallback "キーワードを入力してください".
Feedback welcome at info@dangkang.com.
