Pipe Slope Invert Planner · Effective 2026-05-11 · Updated 2026-05-11 · Contact: yangguangwin@icloud.com

Pipe Slope Invert Planner stores pipe run inputs, saved projects, material assumptions, and generated station sheets locally on your device. The launch build does not create an account and does not upload your pipe planning data to our servers.

What We Collect

How Data Is Used

If the app stores saved runs or local defaults for convenience, that information stays on your device. We only use information you email to support in order to answer your request.

Third-Party Services

The launch build does not include ad networks, analytics SDKs, remote supplier feeds, cloud sync, cloud account systems, AI services, or external APIs. Purchases are processed by Apple through the App Store, and Cloudflare Pages hosts this support and privacy site.

Data Retention

We do not keep your in-app pipe planning data on our servers. Local data remains on your device until you change it or delete the app.
