Privacy Policy
Danggyeoki does not collect any data about you.
Applies to Danggyeoki for iOS · Effective 29 August 2026
The keyboard has no networking code at all. What you type is never written down and never leaves your device, because there is no channel for it to leave through. There is no account, no analytics, no advertising, and no third-party SDK.
What you type
Never stored. The keyboard composes characters and hands them to the app you are using. Nothing is kept. Nothing survives closing the keyboard.
Because nothing is recorded, no passwords, card numbers, or addresses are ever collected. iOS also does not offer third-party keyboards in secure text fields, so the keyboard is not even present when you enter a password.
Network
Not used. There are no servers and no networking code. Every feature works identically in airplane mode. Because no data reaches us, there is nothing for us to sell, share, or hand over, and no breach on our side could expose anything about you.
Gesture statistics
To fit the keyboard to the way you pull, the app counts how far and in which direction your finger moved, how many times, and which row of the keyboard you touched. These numbers stay on the device and can be erased at any time in the app's settings.
Letters are never recorded. The layout has five columns, so a column index would be equivalent to a letter — column indices are therefore excluded from the data entirely. The keyboard measures your hand, not your writing.
Full Access
Everything works without it, and it is off by default. Danggyeoki does not require Full Access, and the keyboard will never ask you for it.
Granting it improves two things: haptics become finer, and the settings you choose in the app carry over to the keyboard automatically. If you leave it off, you choose the same settings inside the keyboard instead.
Even with Full Access granted, what you type is still never stored or transmitted. With no networking, there is nowhere for it to go.
Subscription
The subscription is handled entirely by Apple through the App Store. We never see your payment details, and we do not receive your name, email address, or Apple Account identifier.
Your subscribed state is remembered on your device so the keyboard keeps working without a network connection. Restoring a purchase on a new device is performed by Apple's StoreKit and does not involve any server of ours.
Children
Danggyeoki is rated 4+. Because it collects no data at all, it collects no data from children either. It contains no advertising, no links out of the keyboard, and no user-generated content.
Your rights
Privacy laws give you rights to access, correct, or delete personal data held about you. We hold none, so there is nothing to retrieve or erase. If you would like written confirmation of that for your own records, write to us and we will send it.
Changes
If a future version changes what the app does with data, this page will be updated before that version is released, and the effective date above will change. We will not make a version that collects data quietly.
