Privacy Policy

1. Scope

This policy applies to the Android and iPhone versions of Spot the Difference Classic: World Travel (틀린그림 찾기 클래식 : 세계여행편), operated by Onweald. Sections 2 to 6 describe version 1.5.0 and later. Rankings in earlier versions (1.4.x and below) are described separately in section 7.

The app has no sign-up and no developer-managed accounts. It does not ask for your name, email address, phone number or location, and it does not request access to location, contacts, photos, camera or microphone. There are no ads or analytics tools.

2. Information stored on your device

• Game pictures: The pictures and puzzle data used in the game are included in the app. They are not information about you.
• Play records: Completed puzzles, stars, time taken and when, progress, wrong taps, hints used and remaining, and the state of each country challenge, used to continue games and show results.
• Ranking Mode records: Your best score this week, recent runs (up to 20) and the number of runs.
• Settings: Language, sound effects and music on/off and volume, which tips you have seen, and whether you have purchased the full set of puzzles.

This information stays in the app's storage on your device and is not sent to the developer. It remains until you delete it or remove the app.

3. Rankings (Google Play Games and Game Center)

Ranking Mode uses Google's Google Play Games on Android and Apple's Game Center on iPhone. If you are already signed in to that service on your device, the app connects automatically when it opens. If not, the service's own sign-in screen appears when you start Ranking Mode.

• What is sent: When you finish a Ranking Mode run (10 puzzles), the app sends that run's score to the service. Per-puzzle details and country challenge records are not sent.
• What other players see: Your player name on that service, your score and your rank. Rankings are split into this week and all time, and Android and iPhone rankings are separate.
• What the app reads: To show the ranking screen, the app reads the signed-in player's name and identifier and the leaderboard. This is used only for display. It is not sent to the developer's servers or stored separately.

Your player name, account, profile visibility and stored scores are managed by Google and Apple under their own privacy policies. You can change your name or visibility in that service's settings. The developer does not receive your Google or Apple account email or similar information.

4. Other internet use

The app connects to the developer's content server (Vercel) to download game settings (such as when to suggest an update) and translations. No personal information is sent, but the connection passes access information such as your IP address and the requested path, and the hosting service may keep access logs.

The purchase that unlocks all puzzles is handled by Google Play on Android and the App Store on iPhone. The app does not collect or store payment details such as card numbers. It only asks the store whether the purchase has been made.

5. How to delete stored information

1. Clear device records: In the app, tap Settings → Clear this device's records → Delete and confirm. Completed puzzles, stars, progress, hints, challenge state and Ranking Mode records on this device are deleted. Scores already posted to Google Play Games or Game Center remain.
2. Ranking scores: Records on Google Play Games and Game Center are managed by each service. You can change your profile visibility or delete game data in your Google Play Games profile settings or in your device's Game Center settings. If you want your entry hidden or removed from our rankings, email us at the address in section 6 and we will handle it as far as each service allows.
3. Delete the app: Deleting the app removes the records and settings stored on your device.

Depending on Android device backup or iPhone iCloud/computer backup settings, some records and settings may be backed up and restored when you reinstall. Deleting the app does not delete the operating system's backup copies, so please check your device's backup settings.

6. Children under 14 and contact

The app does not ask for age or date of birth. Whether a child can take part in rankings and whether their player name is visible follow the parental controls of their Google or Apple account. Parents and guardians can contact us at the address below about privacy.

7. Rankings in versions 1.4.x and below

Versions 1.4.x and below used a ranking server run by the developer (Supabase, Seoul region). The following was processed only if you agreed to join the rankings in those versions.

• Information processed: An anonymous account identifier, a nickname generated by the server (which you could change), your store account's country code, and each Ranking Mode run's score and per-puzzle details (answers found, time, wrong taps and hints). Nicknames, flags and scores were visible to other players.
• Deletion: On October 31, 2026 we shut down the ranking server and deleted all of this information and the anonymous accounts along with the server. The developer keeps no copy. From that date Ranking Mode no longer works in 1.4.x apps (the game and purchases still work). You do not need to request deletion.

8. Changes to this policy

If we change this policy, we will post the changes and the new effective date on this page before they apply. The October 31, 2026 revision records in section 7 that the ranking server used by versions 1.4.x and below was shut down and all of its records deleted. The October 30, 2026 revision reflects that from version 1.5.0 rankings use Google Play Games and Game Center, so the nickname, country and per-puzzle details sent to our server, the ranking consent and in-app account deletion are gone. It also notes that game pictures are now included in the app, so nothing is downloaded, and describes the in-app purchase. Rankings in 1.4.x and below moved to section 7. Earlier revisions (September 11, 14, 18, 19 and 21, 2026) covered the 1.4.x ranking server, consent, nicknames, account deletion and keeping the account after reinstalling.
