Pump Mate — Hydraulics

Developer: Mario Cerda (El Pipero) · Last updated: 3 October 2026

Pump Mate has no sign-up or user account. Your projects, calculations, Pump Measurement records and preferences are stored only on your device. The app does use one pseudonymous identifier, created automatically, to authorize the protected pump-curve catalogue and to hold Pump Mate Pro purchase status. This page explains how to delete what is linked to that identifier.

Delete data stored on your device

Delete individual projects and saved results inside the app, or uninstall Pump Mate to remove all of its local data. Nothing on your device is sent to us.

Request deletion of your identifier’s data

  1. In Pump Mate, open Settings → Purchases and tap Support ID to copy it.
  2. Email el.pipero.app@gmail.com with the subject “Pump Mate data deletion request” and paste the Support ID.
  3. We confirm by reply when the deletion is complete, normally within 30 days.

We never ask for a password, payment details or any other identification.
