Privacy Policy

Du Long has no accounts, no ads and no analytics. It never collects your name, email, contacts, location, photos, or anything you type.

Du Long is a puzzle game coming soon to iPhone and iPad (App Store). This page describes the game as it is today. If a future version adds anything that uses your data, such as ads, analytics or in-app purchases, this policy will be updated before that version is released.

What stays on your device

Your nights and stars, mooncakes, called dragons, best scores, saved games and settings are stored locally on your device, in the app’s own sandbox. They’re never sent to me, and they’re deleted when you remove the app.

Game Center (Apple)

If you’re signed in to Game Center, your achievements and leaderboard scores are handled by Apple under your Game Center account. The game reads your achievements back to restore your called dragons and the lore on a new device. I don’t receive your Apple ID or your contacts. Playing never requires signing in. See Apple’s privacy policy.

Tracking

Du Long doesn’t track you. It doesn’t use the advertising identifier (IDFA) and doesn’t share data with advertisers or data brokers.

Your choices

• Sign out of Game Center in iOS Settings → Game Center to stop sending achievements and scores.
• Delete the app to remove all local data.

Children

Du Long doesn’t collect personal information from anyone, including children.

Changes to this policy

If this policy changes, the new version will be posted on this page with a new effective date.
