Privacy Policy

This Privacy Policy explains how PipeSizer ("the app", "we") handles information when you use it. PipeSizer is developed by Mario Cerda (El Pipero). The app is designed to work offline, requires no account, and does not ask for your name, email address, or other personal contact details.

Information stored on your device

• Your calculation inputs, preferences, last calculation, and saved results are stored locally on your device.
• This locally stored engineering data is not uploaded to us.
• You can clear saved results from the app. Local app data is also removed when you uninstall the app, subject to your device platform's backup and restore behavior.

Information collected automatically

PipeSizer uses the following third-party services to understand feature usage and improve reliability. We do not sell this data, use it for advertising, or use it to track you across other companies' apps or websites.

Service	Purpose	Data
Firebase Analytics (Google)	Aggregated usage statistics, enabled only after you opt in through PipeSizer's Settings.	App events, screen views, app/device/OS information, and app-instance identifiers
Sentry	Crash, error, and performance diagnostics used to find and fix reliability problems in production builds.	Crash and error details, stack traces, app/device/OS information, performance diagnostics, and related network metadata

Analytics choice

Firebase Analytics is disabled unless you choose to share anonymous usage data. You can enable or disable it at any time in PipeSizer's Settings. When you disable analytics, the app disables collection and requests that the locally held analytics identifier be reset.

No account, purchases, or advertising

PipeSizer does not require an account, does not contain in-app purchases, and does not display third-party advertising.

Children's privacy

PipeSizer 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 and your choices

• Local calculation data remains on your device until you clear it or remove the app.
• Analytics and diagnostic providers retain information according to their own retention policies.
• To ask a privacy question or request help concerning provider-held data, email el.pipero.app@gmail.com.
