Agenda Tech
• The home-screen widget stayed a blue
box: it shows the date and the coming
events again.
• A change made right after the widget
was drawn — a new event, the lock
turned on — now reaches it at once,
not up to 30 minutes later.
It exists so that your calendar never has to live anywhere but on your phone. A calendar says a lot about a person: their doctors, their lawyers, their job interviews, who they meet and when.
Features
- Four views — Month (swipe between months; dots, titles in the grid or one row per day, pinch to switch), Week, Day and Agenda list
- Events — all-day, description, per-event colour, postal address and GPS coordinates that open in your maps app (with no location permission); deleted by mistake? "Undo" brings it back
- Share — send an event as text or as an .ics file to the app of your choice
- Public holidays — those of nine European countries and the United States, worked out on the phone, off by default
- Recurring events (RFC 5545) — daily, weekly on chosen days, monthly, yearly; ending after N occurrences or on a date; edit or delete a single occurrence
- Reminders — exact alarms, re-armed after a reboot, free delay, your own sound, and a "snooze 10 min" button on the notification
- Encrypted backup — export your whole calendar to a password-protected .atbak file (PBKDF2-HMAC-SHA256 at 600,000 iterations + AES-256-GCM). Keep it anywhere, cloud included: it stays unreadable without your password
- Search — by title, description, place, address or city; accents and case don't matter
- Import from your device calendar — copies what the phone's own calendar apps have already synced onto it, read-only, without any network
- .ics import / export (RFC 5545) through the system file picker
- Optional PIN and biometric lock
- Home-screen widgets, dark theme, in English, French, German, Italian and Spanish
Privacy
- No INTERNET permission. Not "we promise not to" — the app cannot
- Encrypted at rest: SQLCipher (AES-256), master key sealed by the Android KeyStore
- Screenshots blocked (FLAG_SECURE), excluded from Android cloud backups
- Apache 2.0 — every promise on this page is checkable line by line
Limits, honestly
- Not a sync. Importing copies what is on the phone; an event created here does not travel back to the original calendar. That is the price of zero network, and it is deliberate
- No CalDAV, no shared calendars, no invitations — all of it needs a network. You can send an event, not share a calendar
- The encrypted backup is the bridge between your devices, and it is a manual one
