Privacy policy
Last updated 2026-10-02
This policy explains what information RunTheNumbersFirst ("we") collects when you use runthenumbersfirst.com.
Numbers you enter
Calculations run entirely in your browser. The numbers you type into a calculator are not sent to or stored on our servers. If you use "copy link to these numbers", those numbers are placed in the link itself, and anyone you share the link with can see them.
Analytics
We may use analytics services, such as Google Analytics, to understand how visitors use the site, including pages viewed, approximate location, device and browser type. These services use cookies or similar technologies.
Advertising
We may show ads served by third parties, including Google. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your visits to this site and other sites on the Internet. You can opt out of personalized advertising by visiting Google Ads Settings or www.aboutads.info.
Affiliate links
Some links may be affiliate links. If you click one and sign up or buy, we may earn a commission at no extra cost to you. Affiliate relationships do not change how any calculator works.
If you email us, we use your address only to reply.
Children
This site is not directed to children under 13, and we do not knowingly collect their information.
