Cookie Policy

Cookies are small text files that are placed on your device when you visit a website. They help websites remember information, measure usage, and manage basic functionality.

Cookies can be either first-party or third-party:

• First-party cookies are set directly by this website.
• Third-party cookies are set by external services such as analytics or advertising providers.

Similar technologies can include local storage, session storage, and small tracking tags such as web beacons. For simplicity, this policy refers to them collectively as cookies.

We use cookies and similar technologies for four main purposes:

• Analytics and performance measurement, where enabled after consent.
• Advertising delivery and ad personalization controls, where advertising is enabled.
• Functional preferences such as theme mode when you choose to store them.
• Security and consent management.

We do not use cookies to store the raw data entered into calculators.

Calculator inputs are processed in your browser. The site does not use cookies to build personal profiles for sale, and it does not use cookies for purposes outside the scope of this policy.

We categorize cookies by purpose and necessity as follows:

The table below lists the cookies that may be used on the website depending on your consent choices and whether analytics or advertising services are enabled.

Google may update cookie names, durations, or behavior over time. For the latest Google documentation, see Google's cookie information page.

If Google Analytics is enabled on the site, it is only loaded after analytics consent is granted through our cookie controls.

Analytics cookies can help measure:

• Which pages are visited and how long visits last.
• How visitors arrive at the site, such as search or referral traffic.
• General device and browser information.
• Aggregate performance trends that help improve the site.

When Google Analytics is loaded through our consent-controlled script, IP anonymization is enabled in the client configuration.

Ways to opt out include:

• Google Analytics Opt-out Browser Add-on
• Our cookie preference panel, available via the cookie button on every page.
• Your browser cookie controls.

Additional information is available at Google Privacy Policy and Google Analytics privacy documentation.

If advertising is enabled on the site, Google AdSense may be used to display advertisements. Advertising-related requests are managed through the cookie preference system.

When you consent to advertising cookies, ads may be requested in a personalized mode. When you reject advertising cookies but still choose to continue using the site after saving your preferences, ads may be requested in a non-personalized mode, depending on the site configuration.

Opt-out tools and related resources include:

• Google Ad Settings
• Your Online Choices (EU)
• Network Advertising Initiative Opt-out
• Digital Advertising Alliance Opt-out
• Google advertising technologies

Opting out of personalization does not remove all ads. It changes how ad relevance is determined.

Strictly necessary cookies are essential for the website to function properly and do not require prior consent under laws that permit necessary storage for requested services.

Our statistical calculators do not use cookies to store calculation inputs. Calculator data is handled in the browser runtime and is not transmitted to our servers.

You can manage cookies in several ways:

For users in the EEA, UK, and Switzerland, we seek consent before activating non-essential cookies or similar storage used for analytics, advertising preferences, or optional functional storage.

When the banner appears, you can:

• Accept all cookies.
• Reject non-essential cookies.
• Open the preference center and choose categories individually.

If you decline non-essential cookies:

• Analytics will not be loaded.
• Advertising requests, if enabled, are handled in a reduced or non-personalized mode.
• Optional site preferences such as remembered theme mode will not persist.

You can withdraw or change consent at any time by clicking the cookie button and saving new preferences. We store your consent decision in `cc_consent` for up to one year, after which you will be asked again.

Some browsers support a Do Not Track signal. At present, there is no universally applied technical standard for how websites should respond to it.

Like many websites, we do not currently change site behavior solely on the basis of a Do Not Track header. Instead, we provide direct cookie controls and opt-out mechanisms.

We also monitor evolving standards such as Global Privacy Control. If support is added in the future, this policy will be updated accordingly.

We may update this Cookie Policy to reflect changes in the cookies we use, changes in third-party services, or changes in legal and regulatory requirements.

When we make changes:

• The Last Updated date at the top of this page will change.
• For significant changes, such as new cookie categories, we may reset the consent banner so you can review and confirm your preferences again.
• We encourage you to review this policy periodically if you rely on our cookie controls or advertising settings.
