Privacy Policy

This Privacy Policy explains how Pump Mate ("the app", "we") handles information when you use it. Pump Mate is developed by Mario Cerda (El Pipero). We designed the app to be privacy-respecting: it works offline, requires no account, and does not ask for your name, email, or other personal contact details.

Information we do not collect

• We do not require you to create an account or sign in.
• We do not ask for or collect your name, email address, phone number, or precise location.
• Your calculation inputs, saved projects, and results are stored locally on your device and are not transmitted to us.

Information collected automatically

To keep the app reliable and to understand how features are used, the app uses the following third-party services. This data is not linked to your identity and is not used to track you across other apps or websites.

Service	Purpose	Data
Firebase Analytics (Google)	Anonymous, aggregated usage statistics to improve the app. On-device only after you decline; collection is subject to your consent choice.	App events, device/OS type, anonymous identifiers
Sentry	Crash and error diagnostics so we can fix bugs.	Crash logs, device/OS type, diagnostic data
Firebase (Auth & Firestore, Google)	Optional sync of your app preferences (e.g. units, language, theme) across your own devices using an anonymous identifier. No personal profile is created.	Anonymous identifier, preference settings
RevenueCat / Apple App Store	Process and validate the one-time "Pump Mate Pro" in-app purchase and restore it on your devices.	Anonymous purchase/entitlement status

Analytics consent

On first launch the app asks whether you'd like to share anonymous usage data. If you decline, analytics collection is disabled. You can change related choices at any time in your device settings.

In-app purchases

Pump Mate offers a one-time, non-consumable purchase ("Pump Mate Pro"). Payment is processed by Apple; we do not receive or store your payment-card details. Purchase validation and restore are handled through Apple and RevenueCat using anonymous identifiers.

Children's privacy

Pump Mate is a professional engineering tool intended for general audiences and is not directed to children under 13. We do not knowingly collect personal information from children.

Data retention & your choices

• Local data (projects, results, preferences) remains on your device and is removed when you delete the app.
• Diagnostic and anonymous analytics data is retained by the respective providers per their policies and is not associated with you personally.
• To request information about, or deletion of, any data associated with your anonymous identifier, email us at el.pipero.app@gmail.com.
