Stuck? Start here.

Open the HanKey app once, then go back to Settings ＞ General ＞ Keyboard ＞ Keyboards. If it still does not appear, restart your iPhone and check again.

The layout, theme, and settings you pick in the app are saved to storage that the app and the keyboard share. With Full Access off, the keyboard cannot read that storage, so your settings never reach it and it runs with the defaults. What you type is never sent anywhere.

First check that Allow Full Access is on. If it is, close the keyboard and open it again — the new setting is picked up the next time the keyboard opens.

In the app, open HanKey ＞ Korean keyboard. Danmoeum, Mui Danmoeum, Korean QWERTY (Dubeolsik), Cheonjiin, Naratgul, and SKY are all available.

Open HanKey ＞ Keyboard language switching in the app and set which keyboards are included and in what order.

Yes. Use the Secondary keys tab to assign characters or phrases to individual keys. They appear on a long press or a downward swipe.

Go to Settings ＞ Common · Suggestions ＞ Reset learned word suggestions. This clears both frequently used words and next-word predictions, and cannot be undone.

Turn on Settings ＞ Common · Gestures ＞ Move cursor by swiping the whole keyboard, then swipe left or right anywhere on the keyboard. While this is on, swiping a single key left or right for compound vowels is unavailable — the two gestures share the same axis.

Typo correction, the Japanese keyboard, Hanja conversion, translation, kaomoji and decorated text, and the clipboard. It is a one-time purchase. Korean input, themes, and fonts stay free.

Sign in to the App Store with the same Apple Account you bought it with, then open 👑 Unlock Pro in the app and tap Restore Purchase.

Translation needs all three of iOS 26 or later, HanKey Pro, and an installed language pack. Download the language pack from the Translation language screen in the app — the keyboard extension cannot download it.

No. It rewrites the sentence in front of the cursor and offers it as a candidate; nothing changes until you pick one. A wrong automatic fix costs more trust than a missed one.

Copy a theme from the theme-sharing board in the community cafe, then open the Themes/Keyboard tab in the app and tap Import theme.

No. Conversion, learning, typo correction, and translation all run on your iPhone. Translation uses Apple's on-device translation, so it does not go over the network either. We do collect anonymous usage statistics such as screen views and crashes, and those are never tied to what you type.

On your iPhone only. Deleting the app deletes them with it.
