Privacy Policy

Scope and operator

This policy covers the TongYa apps, mini program and related website, operated by Beijing Wanchui Technology Co., Ltd. Available functions vary by client, role, region and school. We process the relevant information when you use those functions.

Information processed

Account and identity information includes username, protected password, user ID, role and any name, nickname, avatar, phone number or email you provide. Apple or WeChat sign-in may provide platform identifiers and authorized profile details.

Educational information includes school and class membership, student details supplied by authorized adults, and reading, learning, quiz, borrowing, course and work records. Submitted content includes feedback, creation prompts, optional photos, images, audio, video and generated works.

Service and transaction information includes purchase and verification records, entitlements, device and operating system details, IP addresses, request/error logs, feature-use events and push identifiers. We do not receive your full payment-card number or Apple payment password.

Purposes and choices

We use information to operate accounts and access controls, reading and educational services, borrowing, requested AI creation, purchase verification, notifications, support and service security. Optional permissions can be refused without affecting unrelated features. We do not sell personal information or use children's information for behavioral advertising.

Permissions

Camera access supports scanning or optional capture; photo access supports selecting or saving images; microphone access supports voice functions; notifications support authorized service reminders. You can manage permissions in device settings. Credentials and preferences may also be stored in the device keychain or local app storage.

Service providers

Apple supports Apple sign-in, App Store transactions and Apple-device notifications. WeChat processes information only for corresponding mini-program or WeChat features. These platforms also apply their own policies.

Storage and AI tasks use providers configured for the relevant service. The project supports Volcengine (TOS, Doubao or speech), DeepSeek, Kling, MiniMax and model-interface channels including OpenRouter and APIYI. Which provider receives a task depends on the feature, model choice and server configuration; a request is not sent to every listed provider. Prompts and reference material you actively submit may be sent to the provider executing the task. Do not upload identifiable children's material without authorization.

We may also disclose necessary information for legal obligations, security investigations or authorized school collaboration. We do not provide personal reading information to advertisers.

Storage and retention

Primary business services and storage are in China. If you access the service from another country, account, educational and usage information will be transferred to China. Third-party sign-in, app stores and some AI interfaces may involve processing elsewhere. Consider this arrangement before using the service.

We retain information for service purposes and applicable legal requirements, using measures such as HTTPS and access controls. Account deletion disables the account, revokes sessions and clears contact details, real name and avatar. Related reading, borrowing, course, work, transaction or security records may not all be erased automatically. Contact us for further deletion; legally required records will have restricted use.

Children

Account and school administration are handled by adults. Children should use TongYa under parent or teacher supervision. Adults supplying children's information must have the necessary authority and should minimize the data supplied. Parents may request access, correction or deletion. Ordinary sign-in or a checkbox is not verification of parental consent under any particular jurisdiction. See the Children's Privacy Notice.

Rights, updates and contact

You may edit account information, manage device permissions or request account deletion in the app. Contact the email below for access, correction, export, deletion or withdrawal requests. We verify identity and parental authority to prevent unauthorized disclosure. Material changes will be communicated appropriately; this page shows its update date. Never email passwords, full identity-document numbers or payment credentials.
