M4S Converter may integrate the following third-party SDKs for WeChat login, WeChat Pay, and local state storage. Actual integrations may differ by version, channel, platform, or region.
The App does not integrate advertising SDKs, does not display third-party ads, and does not collect, use, or share device identifiers for ad delivery, attribution, or personalized advertising.
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.

Notes
Third-party SDKs process information under their own privacy policies. We evaluate the necessity of third-party services and require them to process data lawfully, properly, and only as necessary.
System capabilities, payment capabilities, login capabilities, and app-store capabilities may be provided by operating systems, device manufacturers, app stores, or payment platforms. Their official agreements and privacy policies govern their processing.
Local processing capabilities are mainly used to process files, photos, videos, audio, or app settings on your device. Unless a feature clearly states that network submission is required, we do not upload that content to our servers.
We periodically review SDK integrations based on product features, platform rules, and compliance requirements. For questions about third-party SDKs or information sharing, contact feedback@hshstech.com.
