Information this site may receive
The static pages do not require an account. Web servers and service providers may process ordinary technical information such as IP address, browser type, requested page, referring page, device information and timestamps for security, delivery and aggregate measurement.
Google advertising choices
You can review Google’s advertising and privacy controls through Google’s own settings and policies. Browser settings, consent tools and ad-blocking technologies may also affect cookies and advertising.
Consent messages
Where required, a Google-certified consent-management platform or other consent message may ask you to choose how cookies and personal data may be used. Your available choices depend on location, law and the vendors involved.
Browser-based tools
The calculators and planners on this site run in your browser. Entries are not intentionally transmitted to this website by the tool code. Normal hosting, security and advertising services may still process page-request information.
Third-party links
Pages may link to government sources, maps, search services or other websites. Those services have their own privacy practices. Opening an external link may allow that service to receive ordinary connection information.
Retention and security
Server logs and service-provider records may be retained for operational, security, legal or statistical purposes. No internet service can guarantee absolute security.
Children
This general-audience site is not directed to children under the age required for independent online consent in their jurisdiction. We do not knowingly request children to create accounts or submit personal profiles.
Your choices and inquiries
Use browser controls and any displayed consent tool to manage available choices. Privacy, legal or data-rights inquiries can be submitted through the contact page.
Changes
This policy may be updated when the site’s services, advertising arrangements or legal requirements change. The current version is dated July 25, 2026.
Official sources
Source links are provided for verification. Guidance can change; check the source when safety matters.
