Privacy Policy

Last updated June 25, 2026

Estimatool (“we”, “us”) operates https://estimatool.com. This policy explains what information we do and do not collect when you use our tools and pages, and how third-party advertising works on the site. We have designed the site to collect as little personal data as possible.

The short version

Our calculators and utilities run entirely in your browser. The numbers, letters, and choices you enter are processed on your own device and are not transmitted to, or stored on, our servers. We do not require accounts, and we do not sell personal information.

Information we collect

Information you enter into tools. Inputs to our calculators (for example, monthly sessions or a set of letters) are processed locally in your browser and are not sent to us.

Automatically collected data. Like most websites, our hosting provider and analytics or advertising partners may automatically receive standard technical information such as your IP address, browser type, device type, referring page, and the pages you visit. This is used to operate, secure, and improve the site and to serve advertising.

Local storage and cookies. We may use cookies or local storage to remember lightweight preferences and to enable advertising. You can clear or block these at any time in your browser settings.

Advertising and third-party cookies

This site is supported by advertising. We use Google AdSense to display ads. 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 and/or other sites on the internet.
  • You can opt out of personalized advertising by visiting Google’s Ads Settings, and you can opt out of a third party’s use of cookies for personalized advertising by visiting www.aboutads.info.
  • Third-party ad networks may also use cookies, web beacons, and similar technologies to measure ad performance. We do not control these third-party technologies, and their use is governed by their own privacy policies.

Analytics

We may use privacy-respecting analytics to understand aggregate, anonymous usage (such as which tools are most popular) so we can improve the site. Where used, this data is not used to personally identify you.

How we use information

  • To operate, maintain, and secure the site.
  • To understand aggregate usage and improve our tools.
  • To display and measure advertising that funds the site.
  • To comply with legal obligations.

Your choices and rights

Depending on where you live, you may have rights under laws such as the GDPR or CCPA, including the right to access, correct, or delete personal data, and to opt out of certain data uses. Because our tools do not collect personal data you enter, most requests will relate to advertising and analytics handled by our third-party partners. You can control cookies through your browser and opt out of personalized ads using the links above. To make a request, contact us at the address below.

Children’s privacy

This site is not directed to children under 13, and we do not knowingly collect personal information from children.

Third-party links

Our content may link to external sites we do not operate. We are not responsible for their content or privacy practices, and we encourage you to review their policies.

Changes to this policy

We may update this policy from time to time. Material changes will be reflected by updating the “last updated” date at the top of this page.
