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 HarmonyOS version of M4S Converter. Downloads, updates, account services, payments, refunds, permission prompts, or system capabilities may be provided by Huawei AppGallery, WeChat login, HUAWEI ID, or HarmonyOS login capabilities, Huawei In-App Purchases or HarmonyOS payment capabilities, 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 accessed through the HarmonyOS system picker or an authorized directory | Scanning, merging, conversion, preview, saving, and sharing |
| Account information | WeChat avatar and nickname authorized by you, HUAWEI ID authorization data, and app account number | Login, account binding, VIP entitlement, invitations, and feedback |
| Order information | Huawei In-App Purchases or HarmonyOS payment order ID, product, payment status, and VIP validity | Payment, VIP activation, entitlement restoration, and support verification |
| Feedback information | Feedback text, contact details, and attachments that you actively submit | Issue handling, responses, and troubleshooting |
| Diagnostics and usage | Device model, HarmonyOS and app versions, crash stack, runtime state, and randomly generated install and session identifiers, screens, and operation results | Used only after you accept the Privacy Policy for crash diagnosis, stability, and product improvement |
Permission-Related Information
- Read, select, and save M4S, audio, and video files accessed through the HarmonyOS system picker or an authorized directory, without relying on restricted full-library read access
- Access the network for WeChat login, HUAWEI ID login, Huawei payment, feedback, configuration updates, crash diagnostics, and usage analytics
- Read the device model, HarmonyOS version, app version, and runtime environment information for compatibility and crash diagnosis
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.
Withdrawal and Management
You may disable permissions in HarmonyOS 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.
