Calendar Alarm — Privacy Policy

Last updated: 2026-05-12

Calendar Alarm (“the app”, package com.melncoly.calendaralarm) is published by Colin Blackett (“the developer”). This document describes what data the app accesses, what it does with that data, and what it deliberately does not do.

Summary

The app reads your device’s calendar to schedule alarms. Nothing leaves your phone. There is no server, no analytics, no third-party SDKs, and no internet permission.

What the app reads

The app reads from Android’s local Calendar Provider (android.permission.READ_CALENDAR) to find your upcoming calendar events and schedule a phone alarm for the next one. The fields it reads:

• Event titles, start times, and end times.
• Display names of calendars you’ve added to your device.
• Your RSVP status on each event, so the app can skip events you’ve declined (and, depending on your in-app settings, ones you haven’t responded to).

The Calendar Provider is the same data source the Android system Calendar app reads from. The app does not directly access your Google account, any online calendar service, or any other cloud system.

What the app does NOT do

• Does not transmit data. The app does not declare the INTERNET permission, so it is technically incapable of sending data over the network. Everything happens locally on your device.
• Does not collect, store, or share personal information with the developer or any third party.
• Does not include analytics, crash reporting, or advertising SDKs.
• Cannot modify your calendar. The app declares only READ_CALENDAR, not WRITE_CALENDAR.
• Cannot see your Google account credentials. No GET_ACCOUNTS, MANAGE_ACCOUNTS, or OAuth flows are used.

Other permissions

Permission	Purpose
USE_EXACT_ALARM, SCHEDULE_EXACT_ALARM	Schedule a wake-up alarm at the next calendar event’s start time minus your chosen lead time.
POST_NOTIFICATIONS	Show a status notification (“Next alarm: …”) and the alarm-ringing notification.
USE_FULL_SCREEN_INTENT	Show the alarm UI over the lock screen, like the system alarm clock.
RECEIVE_BOOT_COMPLETED	Re-arm any scheduled alarm after the phone reboots.
WAKE_LOCK, TURN_SCREEN_ON	Wake the device and turn the screen on when the alarm rings.
VIBRATE	Vibrate during the alarm.
FOREGROUND_SERVICE, FOREGROUND_SERVICE_SHORT_SERVICE	Run the alarm-ringing service while the alarm sounds.
REQUEST_IGNORE_BATTERY_OPTIMIZATIONS	Let you (optionally) grant a battery-optimization exemption so alarms remain reliable.

Data retention

The only state the app keeps is your in-app settings — which calendars to watch, lead time, sound choice, vibration pattern, and similar preferences — stored in Android’s private DataStore inside the app’s sandbox. Uninstalling the app removes everything.

Children

The app is not directed at children. It does not collect any data that could be used to identify a user, regardless of age.

Changes to this policy

If the policy changes, the Last updated date above will be updated. Material changes will also be highlighted in the app’s release notes on Google Play.
