Never miss a meeting again.

Calendar Alarm watches your phone's calendar and automatically sets a wake-up alarm for the next event. Dismiss the alarm and it immediately re-arms for the event after that. Add a new event earlier in the day and the alarm moves up to match.

It's a one-app replacement for a habit you've probably tried: manually setting an alarm before every important meeting. Calendar Alarm does it for you, silently, in the background.

== Privacy-first ==

The app has NO internet permission. It cannot send your data anywhere because it cannot connect to the network at all.

• No analytics. No advertising. No third-party SDKs.
• No account sign-in. The app reads your phone's local calendar (the same one Google Calendar populates), nothing else.
• Cannot modify your calendar — read-only access.
• Cannot see your Google account or any other credentials.

Uninstalling removes everything.

== What it does ==

• Auto-arms an exact alarm for the next event in any calendar you choose.
• Configurable lead time: 0, 1, 2, 3, 4, 5, 10, 15, 30, or 60 minutes before the event.
• Pick which calendars contribute (family, work, holidays, all of them).
• Pick which RSVP states matter: events you created, events you accepted, tentative, invited, declined.
• Choose any alarm sound on your device.
• Four vibration patterns: off, short, long, pulse.
• Lock-screen alarm UI like the system clock app — full-screen, big dismiss button, works without unlocking.
• A persistent "Next alarm: …" status notification so you can see at a glance what's queued.

== How it stays current ==

• Watches the calendar in real time while the app is open.
• Re-checks every 15 minutes in the background (the most frequent Android allows for periodic work).
• Re-evaluates the moment you dismiss the current alarm.
• Re-arms after a reboot.

== Permissions ==

• Read Calendar — to see your upcoming events.
• Post Notifications + Full-screen Notifications — to ring the alarm and show it over the lock screen.
• Schedule Exact Alarms — to fire at the right minute.
• Boot Completed, Wake Lock, Vibrate, Foreground Service — standard alarm-app plumbing.

The app has no INTERNET permission, no GET_ACCOUNTS permission, no storage permissions, and no WRITE_CALENDAR permission.
