Privacy Policy

This privacy policy explains what information Reliable Calculator ("we", "us") collects when you use this website, how it is used, and the choices you have.

Information you enter into calculators

Calculators run entirely in your web browser. The numbers and text you enter are not sent to our servers and are not stored by us.

Information collected automatically

Like most websites, our servers record standard request data such as the page requested, the date and time, your browser type and an IP address. We use this to keep the site secure and working, and we keep aggregate page-view counts to understand which tools are popular. We do not use this data to identify you personally.

Contact form

If you send us a message, we store your name, email address and message so we can reply. We do not sell or share this information, and we delete messages when they are no longer needed.

Cookies

We use a small number of cookies and similar technologies. Some are strictly necessary (for example, to remember that you chose dark mode or your privacy choices). Others are set by third parties for analytics and advertising, described below.

Advertising

We use Google AdSense to show 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 visits to this site and/or other sites on the internet.

You may opt out of personalized advertising by visiting Google's Ads Settings, or opt out of some third-party vendors' use of cookies for personalized advertising at aboutads.info. For more information, see how Google uses information from sites that use its services.

Visitors in the European Economic Area, the UK and Switzerland are shown a consent message before personalized ads are served, and can change their choices at any time.

Analytics

We may use Google Analytics to understand how visitors use the site. It collects information such as pages visited and time spent, using cookies. You can opt out with the Google Analytics opt-out browser add-on.

Your rights

Depending on where you live, you may have the right to access, correct or delete personal information we hold about you, and to object to certain processing. Residents of California may request information about personal data categories and opt out of the "sale" or "sharing" of personal information as defined by the CCPA/CPRA. To make a request, contact us at [email protected].

Children

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

We may update this policy from time to time. The "last updated" date below shows when it last changed.
