Your calculator work stays in your browser.

This page explains the local calculator, currency requests, optional analytics and the choices available to every visitor.

Calculator data

Inputs and totals remain on the device

Subscription choices, API usage, prompt samples and calculated totals run in the browser. Prompt text remains in browser memory. A share link places selected plans, usage values and currency in the address when you choose to copy it.

Anyone who receives that address can read the encoded bill and reopen the same calculation. Review the address before sharing it.

Currency conversion

Frankfurter supplies reference exchange rates

The browser requests current USD reference rates from Frankfurter. The request contains the base currency and standard connection information such as the IP address. Calculator inputs stay in the browser and remain separate from that request.

Analytics choices

Optional analytics follow your consent

Google Analytics 4 and Microsoft Clarity can load when their project identifiers are configured and you accept analytics cookies. The Reject choice keeps the visit limited to the core site. Advertising storage and personalisation stay denied. Clarity uses strict masking for this site.

The consent choice is stored in the browser for up to six months and returns when the policy version changes. A Cookie settings link in the site footer reopens the choice panel.

Forms

Launch notifications use a demand signal

The GPU notification form validates an email address, records a submit event and clears the field. The demand event contains its event name only. Notifications open when the site launches.
