Calendar

Your appointments, on this phone and nowhere else. The month on top, the day beneath, what is coming after that, and a widget on the home screen. Any calendar that exports an .ics file — a booking, a flight, your old Google calendar — comes straight in.

What it does

The month with a dot per event, the chosen day beneath it, and the next few weeks after that
Reminders on the minute — 10 minutes, an hour, a day before — with Snooze on the notification; they survive a restart
Repeats every day, week, fortnight, month or year, with an end date if you want one
A home-screen widget: today’s date, today’s events, what is next
Import any .ics file through Android’s own picker, or open one straight from an email; export everything as one file you keep
All-day and multi-day events, a place, notes, six colours

Nothing leaves the phone, and nothing on it is read. The app never touches any other calendar on the device, holds no internet permission, and keeps your events in its own file. The permission list is exactly what a reminder needs — the notification and the exact alarm — and not a byte more.

What it can reach

This is the whole list. Android prints the same thing under Settings › Apps › Permissions once the app is on your phone, and it was not written by us — check one against the other.

Notifications	To show a reminder when its time comes
Exact alarms	So a reminder lands on the minute you set, not whenever Android gets round to it
Run after restart	To set the reminders again when the phone reboots
Vibrate	The buzz with a reminder

Android 8.0 and up. Bought once, yours to keep: no account to make, no subscription, and no upgrade screen inside the app — the licence you buy unlocks it and every version after it.
