Retaining Wall Planner Privacy Policy
Data collection
Retaining Wall Planner does not collect personal data, calculation inputs, result sheets, or local history on developer-operated servers.
Local processing and storage
The app processes wall dimensions and local price inputs on the device. Saved wall plans are stored locally on the device, and the order sheet can be shared only when you choose Apple's standard share sheet; no account, server, or supplier integration is used.
Accounts
Retaining Wall Planner does not require account creation, sign-in, or an online profile.
Analytics and tracking
The app does not use third-party analytics, advertising, tracking SDKs, or cross-app tracking.
Sharing
If you choose a result-sharing action, the app uses Apple's standard system share sheet. The text goes only to the destination you select; the app does not automatically send it to the developer.
Network access and third parties
The core workflow is offline and uses no backend, cloud sync, remote data provider, authentication service, or third-party API.
Data deletion
Delete saved wall plans in the app where the control is available, or delete the app to remove its local storage. There is no online account to delete.
Support email
If you email support, the email thread may be retained as needed to respond to your request. For privacy questions, email yangguangwin@icloud.com.
