ClaimWhen is built to need as little of your data as possible. The calculator runs entirely in your browser — your birth year, benefit amount, and life-expectancy assumption are used only to compute your results and are saved only in your own browser (local storage) so the tool can reopen pre-filled. We never send those figures to our servers.

We ask for your consent before enabling personalized advertising or analytics; you can decline and still use every feature. Google may use cookies to serve ads based on your prior visits; you can opt out via Google's Ads Settings.
Email. If you opt in to the optional cost-of-living-adjustment notice, we store your email address to send a confirmation and the once-a-year COLA update, and for nothing else. You can request deletion at any time.
