Agenda Tech

Agenda Tech is a calendar for Android that keeps everything on your device. No cloud, no account, no ads, no trackers. It declares no internet permission at all, so it is technically unable to send anything anywhere — and you can check that yourself in Android's app settings. 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
