Daesung Kim (“we”) complies with the Personal Information Protection Act of the Republic of Korea and other applicable laws, and handles information about users of the “Mallang Nonogram” app (the “App”) as described below. If this English version differs from the Korean version, the Korean version prevails.
Effective date: 2026-10-22 (announced 2026-10-15 · previous version effective 2026-10-11)
The App has no sign-up or login. We do not receive your name, phone number, email address or any other information that directly identifies you. Your puzzle progress and settings are stored only on your device and are never sent to us. They are deleted when you uninstall the App or tap “Erase progress” in Settings.
The App includes the following tools provided by Google LLC. When you use the App, Google automatically collects the information below.
| Tool | Information collected | Purpose |
|---|---|---|
| Google AdMob (ads) | Device identifiers such as the advertising ID and App Set ID; IP address (used to estimate approximate location); device information (model, OS, etc.); app activity such as ad views and clicks; diagnostics (app launch time, errors, etc.) | Showing ads, measuring ad performance, preventing fraud |
| Google Firebase Crashlytics (error reporting) | Error details when the App crashes or hits an error (error message and stack trace); app version; device information (model, OS version, and device state such as free memory and storage); installation identifier (a random number created for each install); time of the error | Finding and fixing errors in the App |
| Google Firebase Analytics (usage statistics) | App instance ID (a random number created for each install); app activity (puzzle start, clear and quit, how often full-screen ads are shown, and automatically collected events such as first open, sessions and screen views); device information (model, OS, language); approximate region (estimated from IP address) | Improving the App, such as tuning puzzle difficulty |
We use this information only for the purposes listed in section 2: showing ads, analyzing app usage, fixing errors in the App and preventing misuse.
We entrust Google with processing this information to show ads, analyze usage and analyze errors. In doing so, the information is transferred outside Korea.
| Recipient | Google LLC (United States) · Contact: https://support.google.com/policies/contact/general_privacy_form |
|---|---|
| Destination countries | The United States and other countries where Google operates data centers |
| Items transferred | Advertising ID, app instance ID, installation identifier, IP address, device information, app activity, error details |
| When and how | Sent over the network while you use the App |
| Purpose | Showing ads (AdMob), usage statistics (Firebase Analytics), error analysis (Firebase Crashlytics) |
| Retention | Same as section 6 |
| How to refuse, and what happens | You can refuse using the methods in section 7. Turning off usage statistics and error reporting does not limit any App features. If you delete your advertising ID, you will see ads that are not personalized. |
We do not share your information with anyone other than as described in sections 2 and 4.
The App is not directed at children under 13. We do not directly collect information from children. If you are a parent or guardian and learn that information about a child under 14 has been processed, please contact us below and we will help with deletion or other steps.
You may request access to, correction, deletion or suspension of processing of your information. Because the App has no accounts, we cannot identify or look up information about a specific user. Please use the methods in section 7 (turning off usage statistics and error reporting, deleting your advertising ID) and the tools Google provides. For any other request, contact us below and we will respond.
We do not run a server that stores user information. Information sent to Google is encrypted in transit (TLS). The App requests only these permissions: internet access, network state and advertising ID.

If this policy changes, we will announce it on this page and in the App’s update notes at least 7 days before it takes effect. Previous versions are available at the bottom of this page.
