Privacy Policy

Last updated: June 19, 2026

Calculator privacy

The dahej calculator runs entirely in your browser. This static website does not send any calculator data to a server. Your selections, results, and usage stay on your device.

No data collection

We do not use cookies, analytics trackers, advertising pixels, or any other method to collect personal data. The only data stored locally is your theme preference (dark/light mode) in your browser's localStorage.

Local preferences

The website stores a local theme preference in your browser so dark mode or light mode remains consistent across visits. This data never leaves your device.

Contact forms

The contact form is currently a demo and does not submit to a backend server. If a real form service is connected in the future, this privacy policy will be updated accordingly.

Third-party services

The only external resource loaded is Google Fonts (Inter and Outfit typefaces). Google's font service may collect anonymized usage data per Google's own privacy policy.

Changes to this policy

This privacy policy may be updated occasionally. The "Last updated" date at the top reflects the most recent change.
