Local calculations
Calculator values stay in browser memory and are not submitted to a FeeLens server or included in analytics events. The hosting provider may process standard request data, such as IP addresses and browser information, to serve and protect the site.
Optional analytics
Google Analytics loads only after you choose Allow analytics. It may process page views, device information and affiliate-link clicks using cookies. A click is not evidence of registration or trading. Your preference is stored locally; change it with Analytics preferences in the footer. Declining keeps analytics disabled.
