What happens to the dates you enter?

Every calculation runs inside your browser, on your device. Your green card date and every trip you enter are read by the calculator, used to compute a result on screen, and then held only in that page's memory. This site has no backend server, no database, and no API that your dates could be sent to — there is nowhere for them to go.

We do not transmit, store, or log your travel dates. Closing or reloading the page clears them, because they were never sent anywhere to begin with.

Does this site use analytics or tracking?

As of the date at the bottom of this page, this site runs no analytics, no tracking pixels, and no advertising scripts. If that changes, this page will say so, name the tool, and describe what it collects — it will not collect your trip dates or green card date either way, because the calculator never sends that information to any server, including ours.

Like any website, the infrastructure that serves these pages may keep standard connection logs — the kind that record an IP address and browser type for security and reliability. That is ordinary web server behavior, not something this site adds on top, and it is unrelated to the calculator's own input, which stays in your browser.

Does this site use cookies?

No. This site sets no cookies and uses no browser storage to save or track your inputs between visits.
