Privacy Policy

This Privacy Policy explains how HONGKONG VERTEX TECHNOLOGY LIMITED handles information when you use AI CleanKit, an intelligent cleanup and device management application.

Effective date: August 11, 2026

Introduction

By downloading, accessing, or continuing to use AI CleanKit (the "App"), you acknowledge this Privacy Policy. If you do not agree with this policy, please discontinue use of the App.

We may revise this Privacy Policy from time to time. The updated version will apply after it is posted in the App, on this page, or through another reasonable notice method.

1. Information We May Collect

Information You Provide Directly

We may collect information that you choose to provide, including:

Technical and Usage Information

Permission-Based Information

Some features require permissions controlled by your device. Depending on your choices and the App version, these may include Photos, files, notifications, tracking permission, advertising identifiers, diagnostics, and related device capabilities.

2. Photos, Videos, Files, and Cleanup Analysis

AI CleanKit is designed to help users review storage and manage media or files. To provide these features, the App may scan or analyze content that you allow it to access.

Media cleanup analysis is intended to run locally on your device where technically supported. We do not use your private media content for advertising profiling or AI model training.

Deleted or modified content may not always be recoverable. Review selections carefully and keep backups of important content.

3. Notifications and Device Permissions

4. Advertising and Tracking

The App may display advertisements and may work with advertising partners to deliver ads, measure performance, prevent fraud, and understand ad interactions.

5. Analytics and Crash Reporting

We may use Firebase Analytics, Firebase Crashlytics, and similar services to understand how the App is used, diagnose technical issues, and improve reliability.

6. How Information Is Used

Information described in this policy may be used to:

7. Third-Party SDKs and Service Providers

The App may include third-party SDKs or service providers for analytics, crash reporting, advertising, subscription validation, fraud prevention, infrastructure, and product improvement. These providers may process information according to their own privacy policies and legal terms.

Examples may include Firebase services, advertising networks, Apple payment infrastructure, and other technical providers needed to operate the App.

8. Purchases and Subscription Status

In-app purchases and subscriptions are processed by Apple. We do not collect or store your bank card number or full payment credentials. We may receive limited purchase status, product identifier, transaction state, renewal status, or receipt information to provide premium features and support.

9. Sharing and Disclosure

We do not sell your personal information. We may share or disclose information only when reasonably necessary:

10. Children's Privacy

The App is not directed to children under 13 years of age. We do not knowingly collect personal information from children under 13. If you believe a child has provided personal information to us, please contact us so we can review and take appropriate action.

11. Data Retention and Your Choices

We retain information only for as long as reasonably necessary for the purposes described in this policy, unless a longer period is required or permitted by law.

12. International Processing

We are based in Hong Kong, and our service providers may process information in Hong Kong or other regions where they operate. When information is processed across borders, we take reasonable steps designed to protect it in accordance with this Privacy Policy and applicable law.

13. Security

We use reasonable technical and organizational measures designed to protect information against unauthorized access, loss, misuse, alteration, or disclosure. However, no network, device, application, or storage method can be guaranteed to be completely secure.

14. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Updated versions will show a new effective date. Continued use of AI CleanKit after an update becomes effective means that you acknowledge the revised policy.
