Cookie Policy

1. What this policy covers

This website ("the service") uses cookies and similar technologies. This policy explains what cookies are used, why they are used, and how you can control them.

2. How the service works

The calculators on this site run entirely in your web browser. The numbers you enter are processed locally on your device and are not collected by us. The site itself does not set its own tracking cookies.

However, the service integrates Google services that may place cookies or use similar technologies on your device:

• Google Analytics (Google Analytics 4) — used to understand how visitors use the site so we can improve it. This is enabled only with your consent. Google Analytics may set cookies such as _ga and _gid that are used to distinguish unique users and sessions.
• Google AdSense — used to display advertisements that help fund the service. Advertising may involve cookies used to build profiles of interests and show relevant ads. This is enabled only with your consent.

3. Categories of cookies

Strictly necessary

Technical cookies required for the site to function, such as those needed to remember your consent choice. These cannot be turned off through this interface.

Analytics

Cookies set by Google Analytics that help us understand aggregate usage. These are only set when you consent to analytics cookies.

Advertising

Cookies set by Google AdSense for showing and measuring advertising. These are only set when you consent to advertising cookies.

4. Managing and withdrawing consent

When you first visit the service, a consent banner appears. You can accept all, reject all, or manage your preferences. Your choice is stored on your device.

You can change or withdraw your consent at any time by opening cookie preferences, or by adjusting your browser settings to block or delete cookies. Note that blocking strictly necessary cookies may affect how the service works.

5. Third-party cookies

The third-party services described above (Google Analytics and Google AdSense) are operated by Google. Cookies placed by these services are subject to Google's own privacy and advertising policies. We do not control those cookies.

6. Data retention

Retention periods for analytics and advertising data are managed by the respective providers (Google) in accordance with their own policies. We do not set our own retention periods for user data because no personal data is processed on our side.
