Frequently asked questions

Opening documents and converting to PDF

Q. How do I open an HWP file I received in KakaoTalk with Hanjjok?

Press and hold the HWP file in KakaoTalk and choose "Open with another app", or pick "Hanjjok" from the share sheet. On iOS it works the same way from the Files app.

Q. Where is the converted PDF saved?

Choose "Save to Files" on the system share sheet that appears after conversion and you can keep it wherever you like. You can also send it straight to another app such as KakaoTalk or your mail app.

Printing

Q. A landscape page appears as portrait when printing.

Hanjjok detects the orientation of the first page (landscape or portrait) automatically and applies it to the print dialog. If it comes out differently from what you intended, please change the orientation yourself in the system print dialog.

Privacy and removing ads

Q. Are document contents sent anywhere?

No. Hanjjok operates no backend server, and all document processing takes place inside your device. For details, please see the Privacy Policy.

Q. Can I remove the ads?

Yes, this is available. Under Settings → Remove ads (lifetime) in the app, a single purchase removes advertising permanently. If you reinstall the app or change devices, choose Settings → Restore purchase with the same store account you used for the payment and it will be applied again.
