Privacy Policy
This policy explains the limited technical data used by this static site and how Google/third-party advertising technologies may operate.
Information we collect
This is primarily a static informational website. We do not require user accounts. Our calculators run in the visitor’s browser and are designed not to send calculator entries to a site database. Like most websites, hosting infrastructure may process technical information such as IP address, browser/user-agent information, requested pages, timestamps and security logs.
Google advertising and cookies
This site may use Google AdSense. Google and other third-party vendors may use cookies, web beacons, local storage or similar identifiers to serve, measure and limit the frequency of ads. Personalized ads can use information about prior visits to this and other sites where permitted and consented. Non-personalized ads are based primarily on contextual information, but Google explains that cookies or mobile identifiers may still be used for purposes such as frequency capping and aggregated reporting.
Your ad choices
You can manage Google advertising personalization through Google Ads Settings. You can also learn how Google uses information from sites and apps that use its services at Google’s partner-sites information page. Browser controls may also allow you to delete or block cookies, though doing so can affect website functions or advertising.
EEA, United Kingdom and Switzerland
Where required, we use or intend to use a consent management platform that meets Google’s publisher requirements. Google requires publishers serving personalized ads to users in the European Economic Area, the United Kingdom and Switzerland to use a Google-certified consent management platform integrated with the IAB Transparency and Consent Framework. The consent message may list Google and other advertising partners and provide choices regarding purposes and vendors.
Other regional privacy choices
Privacy and advertising rules vary by jurisdiction. Google AdSense privacy messaging and restricted-data-processing options may be used where applicable. Visitors should use the privacy controls presented on the site and the controls provided by Google or their browser.
External links
Articles may link to manufacturers, standards bodies, regulators and other external websites. Those sites operate under their own privacy practices.
Data retention and security
Server logs may be retained for operational, security and abuse-prevention purposes according to hosting and business needs. No internet service can guarantee absolute security.
Children
This website is general-audience consumer information and is not directed specifically to children. We do not knowingly ask children to create accounts or submit profiles.
