Short version: the calculator runs in your browser, and your numbers never leave it.
Last updated: October 20, 2026
Nothing, by design. The site has no accounts, no sign-up, no contact form, and no newsletter. The calculators run entirely in your browser: the income, contribution, and eligibility figures you type are never sent to our servers or anywhere else. There is nothing to leak because nothing is transmitted or stored.
Like most websites, our hosting provider and content-delivery network see your IP address and basic request data in order to serve pages. Pages load the Work Sans typeface from Google Fonts, whose servers therefore see font requests. Once advertising is enabled, ad partners may set cookies subject to their own policies; this section will be updated with specifics before any ad code goes live.
The site sets no cookies of its own. Third parties (fonts, future ad networks) may set their own; your browser's settings control those.
The site is aimed at adult savers (the program itself requires age 18) and does not knowingly collect data from anyone, children included.
If this policy changes materially, the date above changes with it.
