Privacy Policy

Updated November​ 12,​ 2026 Sources and methodology

Family Support Math (“we,” “us”) publishes free child support and alimony calculators. This policy explains what information is processed when you use the site, why, and what choices you have. It is written to cover the Google AdSense program, the EU/UK/Swiss consent rules, and California privacy rights.

Calculator inputs

The numbers you type into a calculator (income, number of children, parenting time, marriage length) are processed in your browser by JavaScript. They are not sent to our server, stored in an account, or used to identify you. The site has no sign-up, no login, and no user profiles. If you reload the page, the inputs are gone.

The site is served as static files. The hosting provider may keep standard server logs that include an IP address, browser type, requested URL, and timestamp for security and reliability. Those logs are not combined with calculator inputs.

Cookies and advertising

When advertising is enabled, Google and its partners may use cookies, web beacons, IP addresses, and other identifiers to serve ads, measure their performance, and limit how often you see the same ad. Google may use the DoubleClick cookie or similar technologies to serve interest-based ads based on your visits to this and other sites. Third-party vendors and ad networks may also place or read cookies on your browser as a result of ad serving.

You can learn how Google uses data when you use partner sites at policies.google.com/technologies/partner-sites. You can opt out of personalized advertising in Google Ads Settings and manage third-party cookies at aboutads.info/choices.

If you are in the European Economic Area, the United Kingdom, or Switzerland, advertising on this site is only enabled with a consent management platform in place, which asks for your consent before personalized ads and certain cookies are used. You can change or withdraw your choice at any time through the consent banner or the privacy settings link. If you decline, you may still see non-personalized ads.

What we do not do

Your privacy rights

Depending on where you live, you may have the right to access, correct, delete, or port personal information, or to opt out of the sale or sharing of personal information. Because we do not operate an account system and do not receive calculator inputs, we may have little or no personal information to act on. Advertising cookies are controlled by Google and its partners; the opt-out links above are the fastest way to limit personalized ads.

California residents may exercise their rights by contacting us at [email protected]. We will respond within the time required by applicable law. We do not discriminate against users who exercise privacy rights.

Data retention and security

Calculator inputs are not retained. Server logs, if any, are kept by the hosting provider for the period needed for security and operations. The site uses HTTPS. No internet transmission is completely secure, but there is no account or payment data on this site to protect.

Third-party links

The site links to official state calculators, statutes, and other resources. Those sites have their own privacy policies. We are not responsible for their content or data practices.

Changes

We may update this policy when the site adds advertising, analytics, or new features. The “last updated” date at the top of the page shows the current version. Material changes will be reflected here before they take effect.
