Hushan Hushan (Shenzhen) Technology Co., Ltd.
Last updated: July 16, 2026
To ensure that M4S Converter can provide core features, keep accounts secure, improve product quality, and comply with applicable laws and platform requirements, we may collect and use personal information as described below. Actual collection depends on the features you use, your authorization choices, your device, app version, and distribution channel.
This document applies to the Android version of M4S Converter. Downloads, updates, account services, payments, refunds, permission prompts, or system capabilities may be provided by Android app stores, WeChat login or in-app account services, WeChat Pay or app-store billing, or the operating system, and may also be governed by their official terms, privacy policies, and on-screen notices.
| Scenario | Personal information | Purpose |
|---|---|---|
| Media files | M4S, audio, video, and output files that you select or import through an authorized directory | Scanning, pairing, merging, conversion, preview, and saving are performed on the device; a file is uploaded only when you actively attach it to feedback |
| Account information | WeChat avatar and nickname authorized by you, app account number, and login state | Login, account binding, VIP entitlement, invitations, and feedback |
| Order and entitlement information | WeChat payment order identifier, product information, payment result, VIP status, and validity | Payment, VIP activation or restoration, and support verification |
| Feedback information | Feedback text, contact details, and attachments that you actively submit | Issue handling, responses, and troubleshooting |
| Crash diagnostics | Device manufacturer and model, Android version and API level, app version and channel, CPU architecture, process and thread, exception type, message, stack trace, and foreground state; the app account number may be included when signed in | Used only after you accept the Privacy Policy to diagnose crashes and improve stability; uploads are disabled in review mode |
| Usage analytics | Randomly generated app-install and session identifiers, app identifier and version, channel, app account number when signed in, QUA (combined app, platform, version, and device runtime information), screen and feature names, operation result, duration, error code, and extended attributes after sensitive-field filtering | Used only after you accept the Privacy Policy and while the app is in the foreground to understand feature usage and improve the product; immutable hardware identifiers are not used |
Permission-Related Information
- After you select files or authorize a directory, read, process, and save M4S, audio, video, and output files
- Access the network for WeChat login, WeChat Pay, account and VIP entitlement, feedback, configuration updates, crash diagnostics, and usage analytics
- Read runtime environment information such as manufacturer, device model, Android version and API level, app version and channel, and CPU architecture for compatibility and crash diagnosis; immutable hardware identifiers and network-interface addresses are not read
Data Minimization and Local Processing
We follow data minimization. Files, photos, videos, albums, or other content that you actively select or authorize are normally processed locally on your device. Unless a feature clearly states that network submission is required, we do not upload that content to our servers.
Account, order, log, and device information is used only for necessary purposes such as login, VIP entitlement, payment verification, customer support, stability analysis, security risk control, and legal compliance.
Local Processing Triggers and Frequency
| Capability/Component | Purpose | Information Processed | Processing Method | Frequency/Background Behavior |
|---|---|---|---|---|
| Local audio-video processing capabilities | M4S scanning, merging, remuxing, audio extraction, and export | Local M4S, audio, and video files selected by the user, processed on device | Read and processed on the device only after the user selects files or authorizes a directory | Processed each time the user starts scanning, conversion, or export; no fixed-frequency background collection or upload |
Withdrawal and Management
You may disable permissions in Android Settings, log out, delete your account, or clear cache in the app. Disabling permissions, withdrawing authorization, or deleting information may make related features unavailable. For requests that cannot be completed by yourself, such as access, correction, deletion, account deletion, or explanation requests, contact feedback@hshstech.com.
