Privacy Policy
Last updated: April 2026
Overview
CalcEngine is a collection of free, browser-based engineering calculators. We are committed to your privacy. This policy explains what data we do and do not collect.
Data We Do Not Collect
- No account registration or personal information is required.
- No values you enter into calculators are sent to our servers — all calculations run entirely in your browser.
- No tracking cookies or cross-site identifiers are set.
- No behavioural profiles are built or sold.
Local Storage
We store a single key (calcengine-theme)
in your browser's localStorage to
remember your light/dark mode preference. This value never leaves your device.
Web Fonts
Pages load the Inter typeface from Google Fonts. Google may log your IP address as part of serving this font. See Google's privacy policy for details.
Hosting
CalcEngine is a statically generated site. Our hosting provider may collect standard server logs (IP address, request path, timestamp) for operational purposes. These logs are not used for marketing and are not shared with third parties.
Changes to This Policy
We may update this policy from time to time. Material changes will be reflected in the "Last updated" date above.
