This policy explains how YueST, operated by Yinhuai Culture, handles information related to use of the service.
Information and purposes
For WeChat QR sign-in, WeChat Open Platform provides the application identifier, openid and, where available, unionid. We also process non-reversible session and terminal-binding digests, sign-in time, and necessary security audit events. Reading material, parsed text, progress, entitlements, and deletion/export requests are processed to provide reading, restricted processing, security, and auditing functions.
Models, retention, and sharing
When you expressly start a generation task, required restricted excerpts and instructions may be sent to the configured model service. Provider, access region, retention, and cross-border facts will be published from verified production configuration before public launch. We do not sell personal information or publicly display WeChat identities or private reading material. Temporary processing files should be removed after success, failure, or timeout.
Your rights
You may request access, copy, correction, deletion, withdrawal of consent, or make a complaint. This first release is not for people under 14. Send service and rights requests to siborn2026@163.com. Material policy changes will be notified appropriately.
