Privacy policy
This Privacy Policy applies to the mobile application Color Express (listed as “Color Express”, package com.huhfeelgood.colorexpress), developed and published by Heo Philgoo (허필구). Last updated: September 14, 2026.
The developer does not collect or store any personal information on any server. The app requires no sign-up, login, or account.
Your level progress, stars, best records and sound settings are kept only in storage on your device and are never transmitted to the developer's server. The app has no sign-up and no account, and the saved data goes when the app goes. The game runs without an internet connection; the network is used only to load ads.
Google AdMob (advertising): advertising identifier (AAID/IDFA), device information (model, OS version, language, country), approximate location derived from IP address, and ad interaction data — used to serve and measure ads, prevent ad fraud, and — where you have consented — to personalize ads. Processed by Google LLC. https://policies.google.com/technologies/ads
Consent. Users in the EEA and the UK are shown a Google UMP consent form on first launch. Those users can change or withdraw their consent at any time under Settings (the gear icon) → Privacy settings in the app. Users in applicable US states are shown a state privacy notice and can opt out of the sale or sharing of personal information. On iOS, App Tracking Transparency (ATT) lets you allow or deny tracking.

| Advertising identifier | Used by Google AdMob to serve and measure ads | You can reset it or turn off personalized ads in your device settings |
| Tracking permission (ATT) | On iOS, to let you allow or deny personalized ads | Declining leaves every feature of the game available |
The developer does not sell or rent your personal information. No information is shared other than the processing performed by the third-party services listed in section 2 (Google LLC) under their own policies.
Your data and settings are stored only on your device and are removed when you uninstall the app. You can reset or delete your advertising ID in your device settings (Android: Settings → Google → Ads; iOS: Settings → Privacy & Security → Tracking). For deletion requests concerning third-party data, contact pgmagician@gmail.com.
