1. Data Minimization
We do not require user account registration for accessing calculators, converters, or city search utilities. We do not collect passwords, precise geolocation, or personally identifiable information (PII).
2. Local Storage
User preferences such as dark mode toggle and recent search history are stored strictly on your device using browser `localStorage`. You can clear this data at any time via browser settings.
3. Third-Party Requests
Calculations are executed client-side inside your browser. Foreign exchange rates and external dataset updates are pre-cached on Cloudflare edge servers so your browser makes zero direct tracking calls to third-party endpoints.
