1. Introduction
Throughout this document, “Studio”, “we”, “us”, and “our” refer to Tuan Indie Studio, the solo studio operated by Tuan. “Games” (or “Services”) means every game, app, website, and related service we publish — including LuaLand, Hueventure, Calm Drift, ColorMix, and any title we release in the future — across the App Store, Google Play, the web, and other platforms. “You” means the person using our Games.
This Privacy Policy explains what information our Games collect, how we use it, and the choices you have. It applies to all of our Games and is designed so you can rely on a single, consistent policy no matter which of our titles you play. We aim to collect as little personal data as possible.
2. Information we collect
Information you provide
Most of our Games can be played without creating an account. If you contact us by email, or choose to use optional features (such as leaderboards or a display name), we receive the information you choose to share.
Information collected automatically
- Device and technical data: device model, operating-system version, language, region, and app version.
- Gameplay data: levels reached, progress, settings, in-app purchase status, and similar in-game events, used to run the game and improve it.
- Advertising identifiers: on ad-supported games, an advertising ID and related signals may be used by ad partners (see “Advertising”).
- Diagnostics: crash logs and performance data that help us fix bugs.
We do not ask for your real name, precise location, contacts, photos, or microphone/camera access unless a specific feature clearly requires it and you grant permission.
3. How we use information
- To operate, maintain, and provide the Games and their features.
- To save your progress and settings and enable purchases such as removing ads.
- To understand how our Games are played so we can improve balance, fix bugs, and design better content.
- To show and measure advertising in ad-supported games.
- To protect against fraud, cheating, and abuse, and to comply with legal obligations.
4. Advertising & analytics
Ad-supported Games use third-party advertising networks — primarily Google AdMob — to display banner, interstitial, and rewarded ads. These partners may use device and advertising identifiers to serve and measure ads, and, where permitted, to show more relevant ads. We also use privacy-conscious analytics to understand aggregate usage.
- You can limit ad tracking in your device settings (for example, “Allow Apps to Request to Track” on iOS, or resetting/limiting your advertising ID on Android).
- Purchasing a “remove ads” option disables the relevant ads on that device.
- For details on Google’s practices, see Google’s Privacy Policy and “How Google uses information from sites or apps that use our services”.
5. Third-party services we rely on
Our Games use trusted third parties to function. Depending on the title and platform, these may include:
- Apple — App Store distribution, in-app purchases, and Game Center leaderboards/achievements.
- Google — Google Play distribution, Google Play Services, and Google AdMob advertising.
- Analytics and crash-reporting providers used to keep the Games stable.
Each third party processes data under its own privacy policy. We share only what is needed for these services to work, and we do not sell your personal information.
6. Data retention
We keep information only as long as needed for the purposes described here — for example, to run the Games, support you, and meet legal or accounting requirements. Much gameplay data is stored on your own device and is removed when you uninstall the Game. Aggregated or de-identified data that can no longer identify you may be kept for analytics.
7. Children’s privacy
Our Games are intended for a general audience and are not directed at children under the age required for consent in your country (for example, 13 in the United States). We do not knowingly collect personal information from children beyond the limited, non-personal data needed to run an app and show age-appropriate ads. Where a Game is directed to children or offered in a kids’ programme, ad partners are configured accordingly. If you believe a child has provided us personal information, contact us and we will delete it.
8. Your rights & choices
Depending on where you live (for example under the GDPR in the EU/UK or the CCPA/CPRA in California), you may have rights to access, correct, delete, or restrict the use of your personal information, to object to certain processing, and to data portability. You can exercise these rights, or ask questions, by emailing us. You also have practical controls at any time:
- Reset or limit your advertising identifier in your device settings.
- Manage tracking permission prompts in iOS or Android settings.
- Uninstall a Game to stop further on-device data collection.
We will not discriminate against you for exercising your privacy rights.
9. Security
We take reasonable technical and organisational measures to protect information. However, no method of transmission or storage is completely secure, and we cannot guarantee absolute security.
10. International data transfers
Our third-party providers may process data on servers in countries other than yours. Where required, we rely on appropriate safeguards for such transfers. By using our Games, you understand your information may be processed outside your country of residence.
11. Changes to this Policy
We may update this Privacy Policy as our Games and the law evolve. We will revise the “Last updated” date above and, for material changes, provide additional notice where appropriate. Continued use of our Games after changes take effect means you accept the updated Policy.
