There is no fixed retention period. Inquiry records are kept only as long as reasonably needed for review, follow-up, site records, recurring issue handling, or legal/security reasons.

Advertising and analytics services

Substantial calculator and guide pages may load Google AdSense code, and public pages load Google tag code. Third-party vendors, including Google, may use cookies or similar technologies to serve ads, measure traffic, detect abuse, and improve their services. These technologies may use information from prior visits to this site and/or other sites to help serve ads or measure how ads and pages are used.

Google's use of advertising cookies enables Google and its partners to serve ads based on visits to this site and/or other sites on the Internet. You can manage or opt out of personalized advertising through Google's Ads Settings. Google also explains how it uses information from sites and apps that use its services.

This site uses Google tag code for measurement. Depending on Google's service configuration, Google may receive information such as pages viewed, browser and device information, approximate location, and interactions with site pages. Where applicable, you can use browser controls or the Google Analytics opt-out browser add-on to limit some measurement activity.

Advertising and measurement choices may vary by location, browser settings, and Google service configuration. This site does not directly sell personal information submitted through the contact form.

Cookies

This site does not require an account for public browsing. Cookies may be set by the site framework for normal security or form behavior, and by third-party services such as Google AdSense, Google tag, ad vendors, or ad networks for advertising, measurement, fraud prevention, and related purposes. Your browser settings may let you block or delete cookies, although some site, advertising, or measurement features may behave differently when cookies are disabled.
