Birthday Sync 0.1.0

First public release: Birthday Sync copies the birthdays from your Android contacts into a
calendar of your choice and keeps the events up to date – on the device, without internet access.

Added

• Contact selection – choose whole contact accounts (Google, device, Exchange and others) or
  individual groups/labels whose birthdays are included (tab Contacts).
• Target calendar – write the birthdays as events into any writable calendar, for example your
  Google calendar, or let the app create its own local “Birthdays” calendar (tab Calendar).
• Event options – all-day or at a set time with a duration, an optional calendar reminder,
  and a title template with the placeholders {name} and {age} (default 🎂 {name} ({age})).
• Automatic sync – daily or weekly in the background (WorkManager) for a range of 1–12
  months ahead; changed settings are applied after a few seconds, Sync now runs it at once.
• Keeps the calendar in step – changed names or birth dates update the events; removed or
  deselected contacts and a shorter range remove them. Events are recognised by a marker in their
  description, so no database is needed and the app picks up its events again after a reinstall.
• Daily notification – at a time you choose, a notification lists today’s birthdays, straight
  from your contacts and independent of the calendar (tab Alerts).
• Guided setup – on first start, one screen per missing permission explains why it is needed;
  every step can be skipped and completed later.
• System checks – the System tab checks permissions, battery optimization, background
  restrictions, app hibernation, exact alarms and Battery Saver, and gives hints for manufacturers
  known to stop background apps.
• 40 languages – English, German and 38 more; many translations are machine-assisted and
  welcome review by native speakers.
• Private by design – no internet permission, no ads, no tracking, no analytics.
