Privacy Policy for Star Hold: TD

Last Updated: April 2, 2026

This Privacy Policy governs your use of the mobile application "Star Hold: TD" (hereinafter referred to as the "App"), developed by ZEUS AI Limited (hereinafter referred to as "we", "us", or "our"). This Policy explains how we collect, use, disclose, and protect your information when you use our App, and complies with applicable privacy laws, including the General Data Protection Regulation (GDPR) for users in the European Union (EU), European Economic Area (EEA), and United Kingdom (UK), and the California Consumer Privacy Act (CCPA) for users in California, USA.

By downloading, installing, or using the App, you acknowledge that you have read, understood, and agree to the terms of this Privacy Policy. If you do not agree with this Policy, please do not use the App.

1. Information We Collect

We collect only the minimum necessary information to provide and improve the App, ensure security, and comply with legal obligations. The information we collect falls into the following categories:

1.1 Device and Technical Information

When you use the App, we may automatically collect certain device and technical information, including but not limited to:

• Device Identifier for Vendor (IDFV) and Advertising Identifier (IDFA) (only if you grant consent via the App Tracking Transparency (ATT) framework in iOS 14.5 and above).
• Device model, iOS version, and operating system information.
• App usage data, such as session duration, gameplay progress, turret placement, and in-app interactions (e.g., merging turrets, selecting power-ups).
• Crash reports and diagnostic data to identify and fix technical issues (collected via iOS official tools).

1.2 Information Related to Third-Party Tools

We integrate third-party tools to support attribution, advertising, and app functionality. These tools may collect and process information on our behalf, subject to their own privacy policies:

• Adjust (Attribution Tool): We use Adjust to track app installs, measure the effectiveness of our marketing campaigns, and conduct attribution analysis. Adjust may collect device information (including IDFA, if consented), IP address, and app usage data for attribution purposes. Adjust's privacy policy can be found at: https://www.adjust.com/terms/privacy-policy/.
• Advertising Tools: We display third-party ads (including interstitial and rewarded videos) in the App to support its free availability. We use the AppLovin Max ad mediation SDK, which aggregates multiple ad networks to deliver ads efficiently. AppLovin Max and its integrated ad networks may collect IDFA (if you consent), device information (such as device model, iOS version), IP address, and app usage data to deliver personalized ads, in compliance with applicable privacy laws and platform policies. Their privacy policies are available at: AppLovin Max, and you may also review the privacy policies of the ad networks integrated within AppLovin Max on AppLovin's official website.
• In-App Purchase (IAP) Tools: We use Apple's official IAP system to process in-app purchases (e.g., premium currency, remove ads). Apple collects purchase information (e.g., product type, purchase date) on our behalf, and we do not store sensitive payment details (e.g., credit card information). Apple's privacy policy can be found at: https://www.apple.com/legal/privacy/en-ww/.

1.3 Game Progress and User-Generated Information

We may collect and store your game progress data, including but not limited to: turret upgrades, tech tree progress, in-run power-ups, and level completion status. This information is stored locally on your device by default, and may be synced to your iCloud account (if you enable iCloud sync) to allow you to resume gameplay across multiple devices. We do not collect or store any personal identifiers (e.g., name, email) unless you choose to provide them voluntarily (e.g., when contacting customer support).

2. How We Use Your Information

We use the collected information solely for the following legitimate purposes, consistent with applicable privacy laws:

• To Provide and Maintain the App: We use device and technical information to ensure the App runs smoothly, fix crashes, and optimize performance for your device. Game progress data is used to allow you to resume gameplay and track your in-app progression.
• To Improve the App: We analyze app usage data (e.g., popular turret combinations, common gameplay paths) to enhance features, balance gameplay, and develop new content that aligns with user preferences.
• To Deliver Advertising: With your consent (via ATT), we use the AppLovin Max ad mediation SDK to deliver personalized ads. AppLovin Max and its integrated ad networks may use IDFA and app usage data to provide relevant ads, while non-personalized ads are delivered if you do not consent to tracking.
• To Measure Marketing Effectiveness: We use Adjust to track the performance of our marketing campaigns, understand how users find and install the App, and optimize our promotional efforts.
• To Comply with Legal Obligations: We may use or disclose your information if required by law, regulation, or legal process (e.g., a court order) to protect our rights, property, or safety, or that of our users.

3. How We Disclose Your Information

We do not sell, rent, or share your personal information with third parties for their own marketing purposes, except as described below:

• Third-Party Service Providers: We share information with third-party tools (e.g., Adjust, AppLovin Max, Apple IAP) solely to perform services on our behalf. These providers are contractually obligated to protect your information and only use it for the purposes we specify, in line with applicable privacy regulations.
• Legal Requirements: We may disclose your information if required by law, or if we believe such disclosure is necessary to comply with a legal obligation, protect our rights, or respond to a security incident.
• Business Transfers: In the event of a merger, acquisition, or sale of all or part of our assets, your information may be transferred to the acquiring entity, subject to the terms of this Privacy Policy.

4. Your Privacy Rights

Depending on your location (e.g., EU/EEA/UK, California), you may have the following rights under applicable privacy laws (GDPR, CCPA):

• Right to Access: You may request a copy of the information we hold about you.
• Right to Correction: You may request to correct any inaccurate or incomplete information we hold about you.
• Right to Erasure: You may request that we delete your information, subject to certain legal exceptions (e.g., if we need to retain it to comply with legal obligations).
• Right to Restrict Processing: You may request that we restrict the processing of your information in certain circumstances.
• Right to Data Portability: You may request to receive your information in a structured, machine-readable format, or to have it transferred to another controller (where technically feasible).
• Right to Withdraw Consent: If you previously consented to tracking (e.g., IDFA collection via ATT), you may withdraw your consent at any time by adjusting your device settings (Settings > Privacy & Security > Tracking > Star Hold: TD).

To exercise any of these rights, please contact us at zeusaihkdev@gmail.com. We will respond to your request within a reasonable timeframe (as required by law, typically 30-45 days).

5. Data Security

We take reasonable measures to protect your information from unauthorized access, use, or disclosure. These measures include:

• Storing game progress data locally on your device (or encrypted in iCloud, if synced).
• Using secure communication protocols (e.g., HTTPS) when transmitting data to third-party service providers.
• Limiting access to your information to authorized personnel only.

Please note that no method of data transmission or storage is 100% secure. We cannot guarantee the absolute security of your information, but we will take all reasonable steps to protect it.

6. Children's Privacy

The App is not intended for use by children under the age of 13 (or the minimum age required by applicable law). We do not knowingly collect personal information from children. If we become aware that we have collected information from a child without parental consent, we will promptly delete that information.

7. Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect changes in our practices, technology, or applicable laws. When we make changes, we will update the "Last Updated" date at the top of this Policy. We encourage you to review this Policy periodically to stay informed about how we protect your information. Your continued use of the App after the changes take effect constitutes your acceptance of the updated Policy.
