Efficient Dollar

Cookie Policy

Last updated on Last updated: 22 Sep 2026

Efficient Dollar uses cookies and browser storage to measure how the site is used, to keep your calculator work and saved results, and to show ads about Efficient Dollar on other platforms. The Privacy Policy has the full detail; this page is the short version.

What Cookies Are

Cookies are small text files stored in your browser. They help remember certain settings when you visit a site. Browser storage (like local storage) is similar, but stays in your browser unless a page sends something from it.

What We Use

  • Analytics cookies (Google Analytics): Used to measure traffic and understand how people use the calculators.
  • Advertising cookies (Google Ads, Meta, Microsoft Advertising, Reddit): Used to measure our marketing and to show ads about Efficient Dollar to people who have visited the site. These companies learn which pages and calculators you used — never what you entered or what your result was. They are not loaded on pages that show your own saved results.
  • Our own cookies: Anonymous identifiers that let us count visits without counting one person twice, and one that keeps your saved results connected to your browser. None of them contains your name or email address.

Some calculators keep the inputs you type in your browser’s storage so your work is still there when you come back. Those inputs are not sent to us.

When you save a calculator result, that result is sent to us and stored on our servers — see the Privacy Policy for what is kept, for how long, and how an anonymous save works without an account.

How to Control Cookies

You can block or delete cookies in your browser settings. Most browsers’ built-in tracking protection, and ad blockers, stop the advertising cookies above. Google provides an optional opt-out add-on for Google Analytics if you prefer not to be measured. The Privacy Policy lists more ways to opt out of personalized ads.

Changes

We may update this policy to reflect changes to the site or analytics tools. The “Last updated” date above shows the latest version.
