Privacy Policy
Effective Date: September 2026
At ConvertUnitTools (available at https://convertunittools.netlify.app/), user privacy is fundamental to our architecture. This Privacy Policy explains our practices regarding data collection, client-side storage, and transparent site operations.
1. Information We Do Not Collect
We do not require user account registration, passwords, credit card credentials, or personal identity verifications to utilize our full suite of conversion tools. We do not sell, rent, or monetize your conversion habits.
2. Browser Local Storage & Offline Caching
To enhance your user experience, ConvertUnitTools utilizes your browser's standard localStorage interface for:
- Theme Preferences (
cut_theme): Saving your selected theme mode (light, dark, or system preference). - Saved Favorites (
cut_favorites): Storing the list of tools you have starred for one-click access. - Offline Application Cache (Service Worker): Caching core application scripts and static shell assets so that calculations work seamlessly when disconnected from the internet.
3. Aggregate Analytics & Performance
We utilize aggregate analytics via Google Analytics 4 (Measurement ID G-QT384G5VE7) to measure general web traffic, page performance, and popular calculator routes.
- IP Anonymization: IP addresses are automatically masked and anonymized by default.
- No Personal Identifiers: We do not log query inputs, calculation results, or personally identifiable data.
- Opt-Out: Users can disable tracking at any time by installing the official Google Analytics Opt-out Browser Add-on or enabling “Do Not Track” in their browser settings.
