PumpChart privacy policy
PumpChart collects nothing. Your data stays on your phone.
What the app does not do
- It has no accounts and no sign-in.
- It has no analytics, no advertising and no tracking.
- Calculations make no network calls. The only network use is the store's own purchase screen.
- No data leaves your device, so the developer never receives it.
What is saved on your device
PumpChart saves your last setup, saved setups, hose coefficients, department and engine names, and drill streak on your phone and nowhere else. Deleting the app deletes that data.
The pump panel card PDF is built on your phone. It goes where you send it from the share sheet. The developer does not receive it.
Purchases
PumpChart Pro is a subscription sold and processed by Apple through StoreKit or by Google through Play Billing. The developer sees no payment details, card numbers or account information.
Changes to this policy
If the app ever changes what it collects, this page changes first and the app update says so. Last updated 2026-10-05.
