Model Engine Builder does not ask for your name, email, or any account. The game itself works offline. The only data leaving your device comes from the advertising and leaderboard services described below.
The free version shows ads supplied by Google AdMob. To serve and measure those ads, AdMob may access your device's advertising identifier, IP address, and basic usage data such as which ads were shown. We do not receive your name, email, contacts, photos, or precise location. Google's handling of this data is described in its Privacy & Terms.
Buying Remove Ads stops all ad requests permanently.
If you are signed in to Game Center, your best score is submitted to Apple's leaderboard under your Game Center nickname. This is optional — the game plays normally without signing in.
Payment is handled entirely by Apple. We never see your payment details.
Your progress, best score, unlocked engines, language and haptics setting are saved locally and removed when you delete the app.
The app is rated 4+ and collects no personal information from anyone, including children.
Questions can be sent to the developer through the app's support page.
