Introduction
This Privacy Policy explains how Hertz ("we", "us", or "our") handles information when you play Color Stack Sort ("the Game"). We are committed to protecting your privacy.
Color Stack Sort does not require registration, login, or any personal information to play. The game is designed to be enjoyed privately.
Information We Collect
The Game itself does not directly collect any personal information. However, our third-party advertising partner may collect the following data:
- Advertising ID (Google Advertising ID / GAID) — used to show relevant ads
- Device type and operating system version
- General location (country level only)
- Ad interaction data (views, clicks)
Game progress (current level, settings) is stored locally on your device only and is never transmitted to our servers.
Advertising
Color Stack Sort displays advertisements provided by Unity LevelPlay (formerly IronSource), operated by Unity Technologies. These ads help us keep the game free.
Unity LevelPlay may use your Advertising ID to show personalized advertisements. You can opt out of personalized advertising at any time:
- On Android: Settings → Privacy → Advertising → Opt out of Ads Personalization
For more information about Unity's data practices, please review the Unity Privacy Policy.
Data Storage
All game progress data (level number, daily undo usage, streak count, preferences) is stored exclusively on your device using Android's local storage (PlayerPrefs). This data is never uploaded to any server.
We do not operate any servers that store your personal data.
Children's Privacy
Color Stack Sort is not directed at children under the age of 13. We do not knowingly collect personal information from children. If you believe a child has provided personal information through our game, please contact us and we will take steps to delete such information.
Your Rights
Depending on your location, you may have rights regarding your personal data, including:
- The right to know what data is collected about you
- The right to request deletion of your data
- The right to opt out of personalized advertising
Since we store no personal data on our servers, requests related to game data can be fulfilled simply by clearing the app's data on your device.
Changes to This Policy
We may update this Privacy Policy from time to time. Any changes will be reflected by updating the "Last updated" date at the top of this page. Continued use of the Game after changes constitutes acceptance of the new policy.
