1. Introduction
Welcome to LightFile Manager (hereinafter referred to as "the App"), a mobile application designed to help users manage device files, supporting functions such as browsing, organizing, copying, moving, deleting, and sharing files (including documents, images, videos, and audio). This Privacy Policy explains how we collect, use, store, and protect your information when you use the App. By accessing or using the App, you confirm that you have read, understood, and agreed to the practices outlined herein. We comply with applicable regulations including the General Data Protection Regulation (GDPR), California Consumer Privacy Act (CCPA), and Apple App Store guidelines to safeguard your privacy.
2. Information We Collect
2.1 File - Related Data
File Metadata: When you use the App to manage files, we may collect non - content metadata such as file names, sizes, formats, creation/modification dates, and storage paths. This information is used solely to enable file management functions (e.g., sorting, searching, and categorizing).
File Content Access (Limited): The App accesses file content only when necessary to perform user - initiated actions, such as previewing a document, playing a video, or compressing a file. We do not read, extract, or store the content of your files without your explicit action.
2.2 User - Provided Information
Account Information (Optional): If you choose to create an account, we may collect your email address (for account verification and password recovery) and a username (for profile management). We do not collect sensitive data like payment information unless explicitly provided for premium features (e.g., cloud storage expansion).
Custom Settings: Preferences such as default view modes, sorting criteria, and favorite folders are stored to personalize your experience.
2.3 Technical and Usage Data
To optimize the App's performance and user experience, we may automatically collect the following non - personally identifiable information:
Device details: Device model, iOS version, App version, and anonymized device identifiers (processed to prevent association with individual users).
Usage metrics: Frequency of App usage, most used features (e.g., file search, batch operations, sharing), and types of files managed (aggregated and not linked to individual users).
Error logs: With your consent, we may collect crash reports or technical errors to diagnose and fix issues. These logs do not contain file content or personal information.
3. How We Use Your Information
Core Functionality: File metadata and custom settings enable essential features, such as organizing files, providing search results, and maintaining your preferred interface layout.
App Improvement: Aggregated technical and usage data helps identify performance bottlenecks, optimize compatibility with different file formats, and develop features that align with user management habits.
Personalization: Based on your usage patterns, the App may suggest relevant tools (e.g., frequently used folders, batch operation shortcuts) to enhance efficiency.
Account Management: Your email address is solely used for account - related activities, such as verifying your account, sending password reset links, or notifying you of important updates (e.g., storage quota alerts for premium users).
4. Data Storage and Security
Local Storage Priority: All file metadata, custom settings, and account information (if applicable) are stored locally on your device by default. You retain full control over this data.
Optional Cloud Features: If you use optional cloud storage integrations (e.g., syncing with iCloud or third - party cloud services), data transfer is governed by the respective cloud provider's privacy policies. We do not host or access your cloud - stored files.
Security Measures: We use industry - standard encryption to protect locally stored data, including account credentials and custom settings. Additionally, you can set up a passcode, Touch ID, or Face ID within the App to restrict unauthorized access to your file management interface.
5. Information Sharing
We will never share, sell, or lease your file content, metadata, account details, or personal data with third parties for marketing, advertising, or commercial purposes.
We may disclose information if required by law (e.g., in response to a valid court order or subpoena) to comply with legal obligations. In such cases, we will provide only the minimum necessary information and notify you unless legally prohibited.
If you choose to share files via third - party platforms (e.g., email, messaging apps), such actions are governed by the privacy policies of those platforms, not this Policy.
6. Your Rights
Access and Control: You can view, modify, or delete file metadata and custom settings through the App's interface at any time. Managing files (e.g., deleting, moving) directly affects the data processed by the App.
Account Management: You can update your account details (e.g., email address, password) or delete your account in the App's settings. Deleting your account will remove your account information from our systems, but locally stored files and metadata will remain on your device unless manually deleted.
Data Portability: You can export your custom settings (e.g., favorite folders, view preferences) as a backup file via the App's export feature.
Opt - Out Options: You can disable cloud integrations, error log collection, or personalized suggestions through the App's or device's settings.
7. Children's Privacy
The App is not intended for use by children under the age of 13. We do not knowingly collect personal information from children under 13. If we become aware of unintended data collection from a child under 13, we will promptly delete such information from our systems.
8. Policy Updates
We may revise this Privacy Policy periodically. For material changes, we will notify you via in - App notifications or email (if you have an account). The "Last updated" date at the top will be updated to reflect changes. Your continued use of the App after the effective date of updates constitutes acceptance of the revised Policy.
