Privacy Policy

Effective October 10, 2026

Information you choose to store

Most SiCalcs calculator calculations run in your browser. When you use favorites, recently used calculators, saved input scenarios, theme or language preferences, those settings may be stored in this browser’s localStorage. Data saved locally can be visible to other users of the same browser profile. Clear browser website data to remove it.

Hosting and diagnostics

Your hosting provider may process IP addresses, request times, technical errors and other server logs needed to operate and secure the website. SiCalcs does not operate a login database in this release.

Advertising and cookies

The current release does not activate Google AdSense or other advertising scripts by default. If Google AdSense is enabled after approval, Google and its partners may process personal data or use cookies/local storage as described in their policies. Before activation, this notice must be reconciled with the actual ad setup and required consent or opt-out controls.

Consent and choices

Where required, advertising will only be enabled after a suitable consent-management solution has been configured for relevant regions. A Google-certified CMP integrating with IAB TCF is required for relevant AdSense serving in the EEA, UK and Switzerland. Do not assume a generic cookie banner alone is sufficient.

Third parties and updates

This policy will be updated when analytics, advertising, contact forms or other services are activated. You can see Google’s privacy information at . Contact information is available on the Contact page. Google Privacy Policy
