Privacy-focused local calendar
Personal events, notes, alarms and most app settings are stored locally on your device. The app does not require a PREMIER 21 CORP account for normal use.
Built-in holiday and calendar layers are displayed inside the app and are not automatically copied into your personal event list.
Optional location access is used only for features that need it, such as local sunrise, sunset, Shabbat times and optional weather. You can keep location-based features disabled and continue using the main clock, alarms and calendar.
Flexible calendar comparison
Enable only the calendars you want to see. You can compare several religious and national calendars at the same time, then disable any layer whenever you no longer need it.
When holidays or observances from several enabled calendars fall on the same day, the calendar uses multiple colors so overlaps are easier to recognize.
Personal events and reminders
Create appointments, birthdays, anniversaries, work events, travel reminders, religious events, notes and other personal entries. Edit them later instead of recreating them.
For each event, choose:
• No alert
• Notification
• Alarm
Your calendar and alarm clock work together so important scheduled events can also appear on the Clock screen.
Backup your data
Create a portable backup of supported events, alarms and settings. Restore later using Merge Restore or Full Restore.
Google Play purchase or subscription status is kept separate from backup files.
Religious Calendar Alarm Clock is designed for users who want a customizable clock, alarm system, personal calendar and multiple holiday calendars together in one private, practical app.
