Privacy policy

This policy explains what information StatHow (stathow.com, "we", "us") collects when you use the site, how it's used, and the choices you have. If you have questions, email info@stathow.com.

Data you enter into our tools

All StatHow calculations and charts are processed locally in your web browser using JavaScript. The data you type or paste into a tool is not uploaded to, stored on or logged by our servers. Charts you download are created on your device. If you close or reload the page, the data you entered is gone unless your browser saves form contents on its own.

Information collected automatically

Like most websites, our hosting provider, Cloudflare, processes basic technical information when your browser requests a page. This can include your IP address, browser type, device type, the page you visited, the referring page, and the date and time of the request. This information is used to deliver the site, keep it secure and fix problems. We don't use it to identify you personally.

We may also use privacy-focused analytics to understand which pages and tools are used most, so we can improve them. Analytics data is reported in aggregate.

Cookies

Cookies are small text files that a website stores in your browser. StatHow itself doesn't need cookies for its tools to work. However, the advertising partners described below set and read cookies, and similar technologies such as web beacons and device identifiers, when you visit our pages.

You can block or delete cookies in your browser settings. Blocking cookies won't stop the calculators from working, but you may still see ads; they just won't be personalized.

Advertising and Google AdSense

We use Google AdSense to show ads on StatHow. Advertising is how we keep the site free. In connection with these ads:

• Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or 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 can opt out of personalized advertising by visiting Google Ads Settings. You can also opt out of some third-party vendors' use of cookies for personalized advertising at www.aboutads.info/choices.
• Other third-party ad vendors or ad networks may also serve ads on the site. You can learn more and opt out of many of them at the Network Advertising Initiative opt-out page.

To learn how Google uses information from sites that use its services, see How Google uses information from sites or apps that use our services.

Visitors in the European Economic Area, the UK and Switzerland will be asked for consent before personalized ads or non-essential cookies are used, and can change their choice at any time.

Fonts and other third-party services

We load fonts from Google Fonts. When your browser downloads a font, Google receives your IP address and basic browser information. Tool pages may also load open-source libraries (such as Chart.js, jStat and KaTeX) from a content delivery network. These requests don't include the data you enter into our tools.

Information you send us

If you email us, we receive your email address and whatever you include in your message. We use it only to reply and to fix the issue you raised. We don't sell it or add you to a mailing list.

How we share information

We don't sell your personal information for money. Information is shared only with the service providers described above (hosting, advertising and fonts) so they can provide their services, or when required by law.

Your privacy rights

Depending on where you live, including California and other US states with consumer privacy laws, you may have the right to know what personal information is collected about you, to request its deletion, and to opt out of the "sale" or "sharing" of personal information for targeted advertising. Because we don't hold the data you enter into our tools, most requests relate to advertising cookies, which you can control with the opt-out links above and your browser settings. You can also email us at info@stathow.com with any request, and we won't treat you differently for making one.

Your browser may send a Global Privacy Control (GPC) signal. Where required by law, we and our advertising partners will treat it as a request to opt out of the sale or sharing of your personal information.

Children's privacy

StatHow is a general-audience educational site and is not directed at children under 13. We don't knowingly collect personal information from children under 13. If you believe a child has sent us personal information, contact us and we'll delete it.

Changes to this policy

We may update this policy from time to time, for example when we add new features or services. The "last updated" date at the top of this page shows when it was last changed.
