French Drain Planner · Effective 2026-06-28 · Updated 2026-06-28 · Contact: yangguangwin@icloud.com

French Drain Planner stores drain route inputs, saved projects, material assumptions, prices, notes, and generated material estimates locally on your device. The launch build does not create an account and does not upload your French drain planning data to our servers.

What we collect

How data is used

If the app stores saved drain plans or local defaults for convenience, that information stays on your device. Device motion may be used while the angle-note panel is open to estimate roll or pitch, but those readings are processed on device and are not collected by us. 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, or cloud account systems. 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 French drain planning data on our servers. Local data remains on your device until you change it or delete the app.
