Restore and reminders
Open Settings → もちもの Plus → 購入を復元 using the purchasing Google account. Weekly reminders require Plus; notification permission and Android power management affect delivery. The isolated demo does not send notifications.
Widgets and deletion
Add from the launcher widget picker and choose a list with the gear button. Lock-screen support depends on OS/launcher. Delete individual lists in the app; clear app storage/uninstall for all records and settings. OS backup behavior depends on device settings.
