Effective: October 2, 2026 · Updated: October 7, 2026 (ad placements in 2.0) · App: Long/Short Duel (롱숏대결), iPhone · iPad · Mac

In short

The developer collects no personal data. There are no accounts and no developer servers. Your progress and settings stay on your device. Ads are served by Google AdMob, and Google processes some device information to do so (see "Ads").

Stored only on your device

• Game progress (coins, cards, points, rewards) and settings (sound, language, effects).
• Diagnostic logs of your last 20 friend duels, for connection issues. Rivals' Game Center IDs are not recorded.

None of it is sent to the developer. Erase it with Reset Data in Settings, or by deleting the app.

Game Center (Apple)

Duels use Apple Game Center for sign-in and matchmaking. During a duel the two devices exchange only game inputs (the cards played and when) through Apple's servers, and your rival sees your Game Center nickname. Game Center is covered by Apple's Privacy Policy. "Share diagnostic log" leaves the app only when you tap it.

Photos (add only)

A record image is added to Photos only when you choose to save it. The app never reads your library.

Ads (Google AdMob)

• Two kinds of ads: rewarded ads you choose to watch (the double-reward key on a match's results screen included), and an interstitial ad every few matches when you return to the lobby (skipped if you watched an ad to the end in the meantime). No ads during or right before a match, in duels, or in the Night Session.
• Non-personalized ads only. The app never asks for App Tracking Transparency and does not use the advertising identifier (IDFA).
• To serve and measure ads and prevent fraud, Google may process device information such as IP address and the coarse location derived from it, a device identifier that is not the advertising identifier (IDFA), device model and OS, ad interactions and diagnostics. The developer does not receive it.
• The app does not ask your age, so every ad request is tagged for users under the age of consent (TFUA). In the EEA and the UK, Google's consent form may appear first.
• More: Google Privacy Policy, How Google uses information from apps that use its services.

Payments

This version has no paid purchases. If added later, Apple's App Store processes payments and the developer never sees payment details.

Other analytics or tracking

None besides the ad SDK above. Crash reports reach the developer anonymously through Apple only if you allow sharing in your device settings.

Children

The developer collects no age, name or contact details. Ads are requested non-personalized and under-age-tagged as above.

Your rights and contact

You can delete the data on your device at any time. Questions or requests: jehyung25@gmail.com

Changes to this policy will be posted on this page with a new effective date.
