This Privacy Policy describes how information is handled in games published under ZXC studio (each, an “App”; collectively, the “Apps”). ZXC studio (“we,” “us,” or “our”) is operated by Manh Nguyen Ngoc. This policy covers our Apps and communications you send to us about them.
1. Information handled by the App
Our Apps may integrate Google AdMob, Google User Messaging Platform, and Firebase Analytics. The services present can differ between games. Depending on the features used, service configuration, device settings, and consent choices, these services may process:
- Device and technical information: device model, operating system, app version, IP address, and app-instance or other permitted identifiers.
- Usage information: app sessions, gameplay or interaction events, and interactions with advertisements.
- Advertising information: ad impressions, ad interactions, and information used for ad delivery, measurement, and fraud prevention.
- Diagnostics: crash reports, performance information, and technical error information processed by the integrated services.
- Consent preferences: choices relating to advertising, privacy notices, and associated consent status.
If you contact us, we receive the information you choose to provide, such as your email address and the contents of your message. Please do not include passwords or payment-card details.
2. How information is used
Information is used to operate and improve the App, understand gameplay and app usage, deliver and measure advertisements, detect invalid activity, troubleshoot technical issues, respond to support requests, and meet applicable obligations.
The information processed varies by game and its enabled features. Advertising identifiers and personalization are subject to the permissions, consent choices, and service configuration applicable to that game.
3. Advertising and privacy choices
Google AdMob provides advertising in the App. Advertising services may use an IP address to estimate a general location and may process permitted identifiers, ad interactions, and diagnostic data. Processing depends on your location, consent choices, device permissions, and the services’ settings.
Where a consent message or privacy-options control is available in the App, use it to review or change the relevant choices. You can also manage tracking permissions in your iPhone’s Settings. Denying tracking permission does not necessarily stop contextual advertising or all analytics and diagnostic processing.
4. Third-party services
Information processed by third-party services is also subject to their policies. You can read more here:
- Google Privacy Policy
- Google Mobile Ads SDK data disclosures
- Privacy and Security in Firebase
- How Google uses information from apps and sites using its services
When you open an advertisement or an external link, the destination service’s own policies apply. Information may be processed in countries other than the country in which you live.
5. Retention and security
Retention depends on the type of information, why it is processed, applicable obligations, and the settings and retention policies of the relevant service provider. Uninstalling the App does not necessarily delete information already processed by third-party services.
We aim to limit access to information and use appropriate safeguards. No method of electronic storage or transmission can guarantee absolute security.
6. Requests and children’s privacy
You may contact us with questions or requests concerning your information, including access, correction, or deletion where applicable. We may need information to verify and locate your request. Our ability to identify analytics or advertising records may be limited when those records are not linked to an identified account.
If you are a parent or guardian and believe a child has provided personal information through the App or a support request, contact us so we can investigate and take appropriate action. Do not include unnecessary information about a child in your initial message.
Number Hunter: Code Arena — game-specific information
This section explains the data practices for Number Hunter: Code Arena. Where the general descriptions above differ, this section applies to this game.
Accounts and online gameplay
You can play as a Guest or choose to register and sign in. We process account email addresses when provided, user identifiers, and gameplay information to operate accounts, online matches, player progress, and virtual-currency balances. Guest access can still involve a game identifier and operational data; it does not mean that no data is processed.
Player chat
We process and store messages sent through the game's chat to provide the chat service. Messages are visible to the players who receive them. Please do not share passwords, payment details, or other sensitive personal information in chat. You can contact our support email about inappropriate messages or privacy concerns.
In-app purchases
Optional diamond purchases are processed through Apple's in-app purchase system. We process purchase history and transaction information to verify purchases, deliver virtual currency, maintain balances, and resolve purchase issues. Please do not send payment-card details to us.
Analytics and service providers
The game uses Firebase for analytics and game operations. Data may include user and app-instance/device identifiers, gameplay and product-interaction events, technical information, and approximate location derived from an IP address. Identifiers and events may be associated with your game account. This information is used to operate and improve the game and understand usage. It is not used for targeted advertising or to track you across apps and websites owned by other companies. The general advertising descriptions above relate to other ZXC studio games and do not describe an advertising purpose for Number Hunter's analytics.
Retention and deletion requests
To request access, correction, or deletion of your Number Hunter account and associated personal information, email ngocmanh92@gmail.com. Include the game's name and your account email or player ID if available. Do not send your password. We may need to verify account ownership before processing a request.
Account, chat, gameplay, and purchase records are retained according to the purpose for which they are needed. Certain records may need to be retained for legal obligations, transaction disputes, security, or fraud prevention. Third-party providers also apply their own retention policies. Uninstalling the game or signing out does not by itself delete your account or server-side data. Contact us for information about a deletion request and any records that must be retained.
7. Changes to this policy
We may update this policy when the App or its data practices change. The date at the top identifies the latest revision. Where required, material changes will be communicated through an appropriate notice.
