This list supplements the Yisi Privacy Policy. Yisi authorises third parties to process only the information needed for a specific service purpose. A third party may also process information under its own privacy policy.

1. Yisi-operated processing

Yisi may use infrastructure for secure hosting, storage, support, diagnostics, AI processing, or image processing. A provider will be added to this list before it is used in a way that changes the types or purposes of personal data processing disclosed to users. Providers will be required to process information under appropriate contractual, confidentiality, and security controls.

2. No unverified SDK disclosures

We do not copy analytics, advertising, social-login, mapping, or other SDK entries from another application into this list. If Yisi integrates a new third-party SDK or partner that can access personal data, we will update this page with its name, purpose, data categories, permissions, processing method, and privacy policy before or when the relevant feature is made available, as required by applicable law.
