What this site collects

Plain Money Math does not ask you to create an account and does not collect names, email addresses, or financial details. The calculators run entirely in your browser — the numbers you type are never sent to a server and are not stored anywhere.

Analytics

Aggregate traffic statistics — pages viewed, rough location by country, referring site — may be collected to understand which articles are useful. This data is not tied to you personally.

Advertising and cookies

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 to you based on your visit to this site or other sites on the internet.

You can opt out of personalised advertising by visiting Google Ads Settings, or opt out of third-party vendor cookies at aboutads.info.

Affiliate links

Some outbound links are affiliate links. If you follow one and sign up for a product, the company may pay this site a commission, and may set its own cookie to attribute that referral. This costs you nothing extra. Affiliate links are disclosed on the pages that carry them.

Your rights

Because this site does not hold personal data about you, there is nothing here to export or delete. For data held by advertising partners, use the opt-out links above or contact those providers directly.
