Update notices
How new versions are announced
Kirin OS and Kirin Sense check the public version record after launch and again when the app returns to the foreground after 24 hours. A notice appears only when the public version number is newer than the installed version.
Updates are delivered through the route that issued the license: the original Lemon Squeezy order, or the product's recovery page for a direct Japanese purchase or complimentary license. The app does not download or install updates automatically.
