Please say which device and iOS version you're on — it usually saves a round trip.
Open Settings in the app and tap Restore purchase. The unlock is tied to your App Store account, not to a device, so it will come back on any device signed in to the same account. If it doesn't, email us with the date of purchase.
Levels 1–20 and the coach through level 10 are free. The one-time purchase unlocks levels 21–60 and the coach at every level, permanently. There is no subscription and nothing else to buy.
On your device only — the app has no account system and never sends anything to a server. That also means progress does not sync between devices, and deleting the app deletes it. This is a deliberate trade for an app that collects nothing; see the privacy policy.
Yes — Settings → Language. The app is available in English, 简体中文, 繁體中文, 日本語 and 한국어, and by default follows your device's language.

No, and it cannot use one. The lessons and the neural opponent are all bundled in the app and run on your device.
