Store listing
By Jong Joon Sun, from the App StoreDescription by Jong Joon Sun Written by the developer, not by AppBrain. Click to read.
That quiet edit is self-censorship. You did it because someone might see.
Lunaco has no server. Entries you want locked stay locked.
Write them as they are.
No sign-up, nothing behind a paywall.
[NOTHING LEAVES YOUR PHONE]
Your events, family records and notes live on the device only, and your calendar data is not transmitted. No account to log into, none to be leaked. It works the same in airplane mode.
What you write into events, family records, trips and tasks is encrypted on the device, and the key never leaves it.
(Holidays are fetched once from an external API. Minimal data is processed for analytics and ads - see our privacy policy.)
[A CALENDAR YOU CAN ACTUALLY WRITE IN]
If you keep entries in your head because they can't go in the calendar, that is the calendar's problem.
Save an entry as private and a curtain hides it. It opens only after a PIN or biometric check. Title, note, location and attendees are encrypted with AES-256-GCM and never surface in widgets, notifications or search.
[BACKUPS ARE ENCRYPTED TOO]
A full backup is encrypted with AES-256-GCM, locked by PIN, passphrase or recovery code, and builds up automatically in your own iCloud or Google Drive. Change phones and one file brings it all back - only text is stored, so years fit in a few MB.
[SEND ONLY WHAT YOU MEAN TO SEND]
Pick a date range or a category, or export one trip or timetable. It merges into the other person's calendar, and duplicates can be skipped or overwritten. Pair by QR and the file opens on that device alone.
[SCHEDULING, AT THE LEVEL OF A DEDICATED APP]
- 23 repeat types - daily, weekly, biweekly, third Monday, every N days. Combine up to 5.
- Gantt bars - multi-day events stretch across the calendar, splitting into lanes when they overlap.
- 225 stickers in 14 categories, so a month reads at a glance.
- Amounts - income and expenses, with a monthly summary bar.
- Categories - 8 built in, add 6 of your own, 18-colour palette.
- Quick entry - long-press a date, or paste several lines and let dates and times be read out.
- Birthdays and anniversaries repeat yearly, with a countdown widget.
[TASKS]
Create tasks by date and check them off. Sweep what slipped with "move to today". They sit alongside your events, encrypted the same way.
[TIMETABLES]
School timetables by period, university timetables by time slot. Colour-code subjects, note teacher and room, track six attendance states. If your weeks differ - rotating shifts, alternating labs - set a 1 to 6 week rotation. The weekly view puts both on one timeline.
[TRIPS]
Destination, dates, day-by-day plans and packing in one place. Packing works in two steps: choose what you're taking, then tick off what's packed. Costs can be entered as an expression and converted at current rates.
[ALSO IN THE BOX]
- ICS import - repeating events unfold intact, and imports can be rolled back
- Moon phases, holidays for 20 countries
- PDF export - month, week, day, year
- Wallpaper studio - timetable or trip over 15 backgrounds
- Widgets - today, mini, moon phase, countdown, timetable, trip
- Notifications - several per event, snooze, hidden titles
- 10 themes, dark mode, two text sizes, adaptive tablet layout, 20 languages
[RECORDS ARE SEEDS]
Keeping a diary is hard, but a calendar you already fill in daily — and Lunaco keeps those entries as plain text, still readable ten years from now.
Lunaco. A calendar you can write in as it is.

Lunaco. Record your entire daily life with a single calendar.
