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.
