Cookie Policy

What Are Cookies?

Cookies are small text files stored on your device that help websites remember information about you. They are essential for modern web functionality and user experience.

Cookies We Use

Essential Cookies

These cookies are necessary for the site to function:

Session ID: Keeps you signed in to your account.
Security tokens: Prevent unauthorized access and form hijacking.
Cookie preferences: Remember your cookie consent choices.

You cannot disable essential cookies; the site will not work without them.

Analytics Cookies

We use Google Analytics to understand how users interact with our site:

Pages visited and time spent on each page.
Calculators used (but not your input values).
Device type and browser information.
Approximate geographic location (country/region).

This data is aggregated and anonymous; you can opt out anytime using the Analytics toggle in our cookie settings.

Advertising Cookies

Math of Money may display ads via Google AdSense. Google and its partners may set cookies to:

Show you ads relevant to your interests.
Track ad performance and prevent fraud.
Build a profile of your interests across websites you visit.

Analytics and Advertising are controlled by separate toggles in our cookie settings — you can, for example, allow analytics while keeping advertising off. Both default to off (Consent Mode "denied") until you choose, per Google's Consent Mode v2 requirements. If your browser sends aGlobal Privacy Control signal, we treat that as an opt-out of ad personalization automatically, and the advertising toggle stays off regardless of what you pick.

Where ads are shown, they load only after the page itself has loaded. Until you allow advertising (and always when advertising is off or Global Privacy Control is on), we ask Google for non-personalized ads, which are chosen from the page's content rather than your browsing history. With Consent Mode set to "denied," Google doesn't use advertising cookies for those ads. For details, seeHow Google uses information from sites or apps that use our services.
