Privacy Policy

Effective Date: August 13, 2026 | Last Updated: November 5, 2026

This Privacy Policy explains how GZ Medi Group (HK) Company Limited ("we", "us", "our") collects, uses, stores and protects your information when you use the Clean Up Storage: Al Cleaner mobile application ("the App"). This policy is intended to comply with applicable U.S. privacy laws, including CCPA/CPRA, COPPA, FTC privacy guidelines and the Apple App Store Review Guidelines.

Important Notice: Clean Up Storage: Al Cleaner is designed as a local-first storage cleaning utility. Photo, video, contact, calendar and file scan results are generally processed on your device to help you find duplicates, similar items, large files, screenshots, blurry photos or other content you may choose to review and delete. We do not sell your personal information or use your private media content for advertising.

Please read this policy carefully before using the App. By continuing to use the App, you confirm that you have read and understood this policy.

1. Information We Collect and Use

We process information only in line with the principles of lawfulness, fairness, transparency and necessity.

1.1 Core Cleaning Data (On-Device First)

Photos and videos: The App may analyze selected or permitted photos and videos to identify duplicates, similar media, screenshots, screen recordings, blurry photos, large videos, old files and other storage categories. This analysis is generally performed on your device.
Cleaning suggestions: Suggested duplicates, similarity groups, file sizes, dates, albums, storage estimates and cleanup results may be generated and stored locally to provide App features.
Contacts and calendar items: If you grant permission, the App may analyze contacts or calendar entries to identify duplicates, incomplete records or items you may choose to merge or delete.
App preferences: Cleaning filters, scan history, selected categories, language settings and other preferences may be stored locally to provide a consistent user experience.

1.2 System Permissions

We may request the following permissions to deliver features. You may withdraw or change permissions at any time in your device settings:

Photos: for scanning, grouping, previewing and deleting user-selected or permitted photos and videos. The App does not delete media automatically without your action.
Contacts: optional, for finding duplicate or incomplete contacts and helping you review, merge or delete selected contact records.
Calendar: optional, if available in your App version, for identifying duplicate or outdated calendar events you may choose to review or remove.
Files / Document Picker: optional, for reviewing user-selected files or exported cleanup reports where supported.
Network: for crash diagnostics, analytics, customer support and security-related operations.
Notifications: optional, for cleanup reminders, service notices or other App-related alerts.

1.3 Technical Data and App Events

To improve stability, performance and user experience, we may collect technical data such as device model, iOS version, app version, crash logs, diagnostic events, general region, language setting, feature usage statistics, scan performance metrics and network status. Some technical data and identifiers processed by third-party SDKs may constitute personal information, even if they do not include your name. See Section 2 for information about Meta SDK data processing.

2. Third-Party Services and SDKs

We use third-party services only where reasonably necessary for App functionality, analytics, advertising measurement and attribution, crash reporting or customer support. These providers are subject to security and data protection review.

Apple Photos, Contacts, Calendar and iOS Frameworks
- Purpose of processing: Provide access to user-permitted media, contacts, calendar entries, local deletion controls and device storage-related features.
- Categories of data processed: User-selected or permitted photos, videos, metadata, contact fields, calendar entries and local scan results processed for cleanup features.
- Third-party privacy policy: https://www.apple.com/legal/privacy/
Firebase Crashlytics (Google), if included in your App version
- Purpose of processing: Collect app crash logs and technical error reports to fix bugs and improve app stability.
- Categories of data processed: De-identified installation identifier, crash stack details, device model, operating system version and app version.
- Third-party privacy policy: https://policies.google.com/privacy
Meta SDK for iOS (FBSDKCoreKit / Facebook Core SDK)
- Provider: Meta Platforms, Inc. and its applicable affiliates.
- Purpose of processing: Support app event measurement and, where enabled, measure advertising performance, attribute app installs or conversions to campaigns, and optimize advertising. The features used and data transmitted depend on the SDK configuration and your privacy choices.
- Categories of data that may be processed: App and SDK version, device model, operating system, IP address, app or installation identifiers, and app events such as app activation, installs, or feature interactions, where event logging is enabled. The advertising identifier (IDFA) may be accessed only where available and permitted by your App Tracking Transparency authorization. Not all listed data is collected in every configuration.
- Data sharing and use: When enabled, the SDK sends relevant event and technical data to Meta. Meta may match it with other information it holds, including information associated with a Meta account, where permitted by law and your choices, for measurement, attribution or advertising purposes. Meta processes information under its applicable terms and privacy policy.
- Private cleanup content: Photos, videos, contact records, calendar entries, file contents and detailed local scan results are not intended as Meta app event data and should not be included in event names or parameters.
- Your choices: Where Apple's App Tracking Transparency framework applies, we request permission before tracking. You can change that permission in iOS Settings > Privacy & Security > Tracking. Declining permission prevents access to IDFA and tracking that requires that permission; it does not necessarily stop all permitted SDK communications or non-tracking measurement. You may also manage applicable advertising preferences in Meta's Accounts Center.
- Third-party privacy policy: https://www.facebook.com/privacy/policy/
- Meta Business Tools Terms: https://www.facebook.com/legal/technology_terms
Analytics services, if included in your App version
- Purpose of processing: Collect aggregated or de-identified usage statistics to understand feature performance and improve product experience.
- Categories of data processed: De-identified device information, app events, non-precise geographic data, app version and network status.

3. How We Use Information

To provide storage cleanup, duplicate photo detection, similar media grouping, large file review, contact cleanup, calendar cleanup and related utility features.
To save your preferences, scan results and cleanup settings.
Where enabled and permitted by applicable law and your privacy choices, to measure app events, attribute installs and conversions, and evaluate or optimize advertising through Meta SDK.
To diagnose crashes, fix bugs, prevent abuse and maintain security.
To respond to your support requests and legal requests where required.

4. Data Storage, Deletion and Cross-Border Transfers

Storage: Core scan results and preferences are generally stored on your device. Analytics, crash diagnostics and Meta SDK event or technical data may be processed and retained by the relevant providers under their applicable policies. We retain information we control only for as long as reasonably necessary for the purposes described in this policy or as required by law.
User-controlled deletion: The App may help you identify content for deletion, but you are responsible for reviewing selected items before confirming deletion. Deleted items may be handled by iOS and Apple Photos rules, including the Recently Deleted album where applicable.
Backup responsibility: You are responsible for maintaining backups of important photos, videos, contacts, calendar entries and files before deleting or modifying them through the App.
Cross-border transfers: As the App may be distributed globally, limited technical and SDK event data, identifiers and other technical data may be transferred to and processed on servers outside your country or region, including the United States, by Meta or other providers. We use reasonable safeguards designed to protect such data in accordance with applicable law.

5. Your Privacy Rights (U.S. Consumers)

If you are a consumer located in the United States, you may have the following rights under applicable U.S. privacy laws:

Right to Know: Request details of the personal information we process about you.
Right to Delete: Request deletion of personal information we hold, excluding data stored only on your device or data retained where legally required.
Right to Correct: Request correction of inaccurate personal information.
Right to Opt Out of Sale/Sharing: We do not sell your personal information for money. Depending on the enabled Meta SDK features and how data is used, disclosure of identifiers or app events for advertising may constitute "sale," "sharing" or targeted advertising under applicable state law. Where applicable, you may contact us using Section 10 to exercise your opt-out rights. You may also withdraw iOS tracking permission as described in Section 2.
Right to Limit Use of Sensitive Personal Information: We do not use sensitive personal information for purposes that require a limitation right under California law.
Right to Non-Discrimination: We will not discriminate against you for exercising your privacy rights.

6. Children's Privacy (COPPA)

The App is not intended for children under the age of 13. We do not knowingly collect personal information from children under 13. If we become aware that we have collected personal information from a child under 13, we will delete it as required by law.

7. Data Security

We use reasonable administrative, technical and organizational measures designed to protect information processed by the App. However, no method of transmission or storage is completely secure. You are responsible for keeping your device, Apple ID, backups and local App access secure.

8. Cleanup Accuracy Notice

The App's duplicate, similarity, large file, blurry photo, contact and calendar cleanup suggestions are estimates. The App may misclassify items or fail to identify some items. You should review all selected content carefully before deleting, merging or modifying it.

9. Changes to This Privacy Policy

We reserve the right to update this policy as required by law or for operational reasons. The latest version will be posted in the App or on the relevant policy page with an updated "Last Updated" date. Your continued use of the App after changes take effect constitutes your acceptance of the revised policy.
