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.
Open-source components are mainly used for local feature implementation. Files, photos, videos, or other content are normally processed on your device, and these components do not independently upload your 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.
