Privacy Policy

Last updated: April 9, 2026

This Privacy Policy describes how FireTools apps handle your information. This policy applies to all FireTools applications: Sprinkler Hydraulic Calc, Pipe Schedule Sprinkler, Fire Pump Sizer, Standpipe Calculator, Fire Alarm Calculator, Hazard Classification, Water Supply Analysis, Hanger Spacing Calc, Fire Extinguisher Calc, and NFPA Code Reference.

Information We Collect

Our apps are designed with privacy in mind. We collect minimal information:

• No personal information — We do not collect names, emails, or phone numbers.
• No account required — All apps work without any sign-up.
• Calculations stay on your device — All calculation data and history are stored locally on your device and never transmitted to our servers.

Third-Party Services

Our apps use the following third-party services:

• Google AdMob — Displays banner ads in the free version. AdMob may collect device identifiers and usage data for ad personalization. See Google's Privacy Policy.
• Google Play Billing — Processes in-app purchases (Pro upgrade). Purchase data is handled by Google Play.
• Firebase Crashlytics — Collects anonymous crash reports to help us improve app stability. No personal data is included.
• Firebase Analytics — Collects anonymous usage data (screen views, feature usage) to help us improve the app experience. No personal data is included.

Pro users do not see ads, so AdMob data collection does not apply to them.

Data Storage

All app data (calculation history, settings, purchase status) is stored locally on your device. We do not operate any servers that receive or store your data.

Disclaimer

FireTools calculators are provided for reference purposes only. They are not a substitute for professional fire protection engineering design. Always verify calculations with applicable NFPA codes and consult with a licensed fire protection engineer for actual system design.

Children's Privacy

Our apps are not directed at children under 13. We do not knowingly collect information from children.

Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated date.
