The app is free to download, and the first five letters are free to read. A one-time in-app purchase — Unlock All Letters ($3.99) — unlocks all 36 letters, forever. There is no subscription, no energy system and no daily cap.
No. Readers who bought the app before it went free are unlocked automatically — open the app and everything is there. If it ever does not recognize you, use Restore Purchase in the app with the same Apple ID.
No. The current version shows no advertising. Should ads be introduced for free readers in a future update, the unlock will remove them all.
The story is available in both English and Simplified Chinese, complete in either — all 36 letters and the whole interface. The app follows your device language.
Yes. The unlock is tied to your Apple ID — the same purchase works on every device signed in with it. Use Restore Purchase after reinstalling.
Progress is stored on your device only — there is no account and no cloud backup. Reinstalling the app or switching to a new phone will start the story over. The unlock, however, is never lost — it restores with your Apple ID.
The 9:30 pm reminder is optional. Turn it off in iOS Settings › Notifications › The Midnight Mailbox.
Both the download-era purchase and the in-app unlock are handled by Apple. To request a refund, use Apple's Report a Problem page (reportaproblem.apple.com).
