9. Auto-Start or Associated Start Instructions

To better serve you, this application may use auto-start functionality in specific scenarios:

  • Skincare Reminder Related: To ensure you receive timely morning and evening skincare log reminders, this application needs to use auto-start capability. When the system restarts or the application updates, the app will automatically restore your set reminder notifications to ensure continuity of your skincare plan. This auto-start behavior is necessary to implement the reminder function.
  • System Broadcast Listening: This application listens to system broadcasts (such as device restart completion, application updates, etc.) to reschedule your skincare reminders when necessary. This ensures that your personalized reminder settings work normally even after system maintenance.
  • Data Synchronization Guarantee: To ensure your skincare data and settings can be properly synchronized and restored after system restart, the application may automatically start related services in the background. This helps protect your skincare records and personal settings from being lost due to system restart.
