Privacy Policy
Information about data, local storage, cookies, Analytics, AdSense and privacy choices on Calcunia.
Transparency
Detailed information
Calculator inputs
Calculator values are designed to be processed in your browser. Routine calculations do not require a user account and do not need to send the numbers you type into a server database operated by Calcunia.
Local preferences
Calcunia may use browser local storage for essential preferences such as language, favorites and cookie choices. These preferences remain on your device unless you clear site data or browser storage.
Cookies and similar technologies
Essential storage keeps the site usable. Optional services may use cookies, local storage or similar technologies for measurement or advertising only when the site configuration and your consent state allow them.
Analytics
Google Analytics may be used to understand aggregate page usage, technical performance and navigation patterns. Calculator input values should not be intentionally sent as analytics event parameters.
Advertising and Google AdSense
Calcunia may use Google AdSense to validate the site and display clearly identified advertising placements. Google and its partners may use cookies or identifiers to serve, measure and limit ads according to user settings, consent signals and applicable law.
Consent in regulated regions
For visitors in regions where consent is required, advertising and analytics features should respect the displayed consent choice. Personalized ads should remain disabled unless a compliant consent-management setup and legal validation are in place.
Third-party providers
Third-party services such as Google may process technical identifiers, device information, approximate location derived from network data, ad interactions and aggregated usage signals under their own policies.
Retention
Local preferences remain in your browser until deleted. Aggregate analytics or advertising logs, when enabled by third parties, are retained according to the relevant provider settings rather than calculator inputs stored by Calcunia.
Security
The site uses HTTPS, restrictive security headers and client-side calculation patterns to reduce unnecessary exposure. No website can guarantee absolute security, so avoid entering confidential personal data when a calculation does not require it.
Your choices
You can clear local storage, adjust browser cookie controls, refuse optional cookies where a banner is shown and use Google advertising controls to manage personalized advertising preferences.
Contact
For privacy questions, correction requests or advertising concerns, contact Calcunia from the contact page and include the relevant page URL when possible.
