Privacy Policy

1. Information we process

Account information includes your username, email address, display name, sign-in provider identifiers, authentication and session information, and a password hash if you set a password. Sign in with Apple supplies the identifier and any name or email you choose to share, including a private relay address when you use Hide My Email. Optional WeChat sign-in supplies the authorization and profile information needed to connect your account, which may include an OpenID/UnionID, nickname and profile photo.

If you choose a profile photo, the selected image is cropped and uploaded to your account; the app does not upload your entire photo library. Signed-in learning records may include the content identifier, progress and activity timestamps. Some preferences and reading-path completion records remain only on your device. Notifications use an APNs device token, platform and notification environment linked to your signed-in account when you enable them.

Membership processing includes an app user identifier, purchased products, transaction or purchase history, and entitlement status. Requests to our service also generate necessary technical and security information, such as IP addresses, request timestamps and errors. Information or attachments you voluntarily send to support are used to address your request. We do not ask for your payment-card details, contacts or precise location to provide these features.

2. Why we use information

We use this information to create and secure accounts, authenticate you, synchronize your profile and learning records, provide public and member content, verify and restore purchases, send enabled content or account notifications, prevent misuse, diagnose service problems and respond to support requests. We also process records needed for accounting, legal obligations and resolving disputes.

We do not sell personal information, collect the advertising identifier (IDFA), or track you across other companies’ apps and websites for targeted advertising or advertising measurement. The app does not send events through a third-party advertising analytics SDK. Necessary account, purchase and security processing still occurs; this is not a claim that no data is collected.

3. Apple, RevenueCat and other providers

Purchases of digital membership in the iOS app use Apple In-App Purchase. Apple handles payment, subscription management and refund decisions. RevenueCat processes app user identifiers, products, transactions and entitlements to validate membership and support purchase restoration. An identifier may be anonymous before sign-in and becomes associated with your account when you sign in. We do not receive or store your full payment-card details from Apple. Website checkout is separate and is offered only when enabled. The website integration is Alipay: if you use an enabled Alipay checkout, we associate the order number, membership plan, amount/currency, payment status, transaction reference and timestamps with your service account. Alipay receives the merchant order number, amount and product description, processes payment through its own payment account system, and returns a transaction reference and payment status for our server to verify. This does not change the Apple In-App Purchase method used for digital membership inside the iOS app.

Apple provides Sign in with Apple and push delivery. WeChat/Tencent processes the authorization you choose to initiate through WeChat. Our hosting, object-storage/CDN, email and security providers process the information necessary to host content, operate accounts, deliver requested communications and protect the service. We limit disclosure to these purposes, your instructions, or circumstances required by law or necessary to protect users and the service. These providers may also apply their own privacy policies.

4. Your choices and permissions

You can use Sign in with Apple or a username and password without installing WeChat. WeChat is an optional sign-in method where available. If your account was created with WeChat, you can link Apple or set a password while signed in, and save your username to use the same account later without WeChat. Contact support if you no longer have access to any sign-in method.

You can decline notifications and continue using the app, or change notification permission in iOS Settings. PhotosPicker lets you choose a specific profile image; you can replace or remove the uploaded avatar in your profile. Saving an image to Photos uses the relevant iOS permission and does not give us your photo library. Refusing an optional permission does not remove access to unrelated features.

5. Retention and security

We keep account, profile, membership and learning information while it is needed to provide the service. After account deletion, we remove the account and associated personal information that is no longer needed. Financial or transaction records legally required for accounting, tax, fraud prevention or disputes may be retained separately with direct account links removed and identifying information anonymized or minimized as permitted by law. Where backups exist, residual copies are handled under applicable retention and deletion obligations.

We use encrypted transport, access controls and restrictions on administrative access to protect information. No internet service can guarantee absolute security. Retention depends on the purpose and applicable obligations rather than an unconditional promise to erase every record immediately.

6. Deleting your account

In the current iOS app, open Account > Settings > Account & Security > Delete Account and follow the on-screen confirmation. This initiates account deletion rather than merely signing you out. The process removes account information and associated profile, learning, authentication-session and notification associations, subject to the necessary retained records described above. You may lose saved learning history and account-linked access.

Before deleting your account, review and manage any active subscription in iOS Settings > your Apple Account > Subscriptions. Deleting the account or uninstalling the app does not automatically cancel an Apple subscription or issue a refund. Apple handles subscription cancellation and refund requests separately. This website provides instructions; it does not delete accounts through a web form.

7. Access, correction and privacy requests

You can update your name and avatar in the app, manage notification permission, and initiate account deletion as described above. For access, correction, a privacy question or help with an inaccessible account, contact support@lingxiaoyao.cn. Provide only the account information needed to identify the issue; do not send your password or full payment-card details. We may verify your identity before disclosing or changing account information.

8. Children, updates and contact

The service is intended for adults interested in learning, independent development and content creation, and is not directed at children. If you believe a child has provided personal information inappropriately, contact us. We update this policy when our practices change and publish the current version and date here. For support and privacy matters, contact support@lingxiaoyao.cn.
