Our calculators run in your browser
The numbers you type into our calculators are processed on your own device. They are not sent to us. If you use a "share link", your inputs are stored in that link's address, and anyone you send it to can see them. Some tools save your last project in your browser's local storage so you can come back to it. You can clear this at any time in your browser settings.
Analytics
We use Google Analytics to understand how visitors find and use the site, for example which calculators are opened most. It uses cookies. Google processes this data under the Google Privacy Policy, and you can opt out with the Google Analytics opt-out browser add-on.
We use Microsoft Clarity to see how visitors use our pages, through heatmaps and session recordings of clicks, scrolling and mouse movement. This helps us find calculators that are hard to use. Clarity masks what you type into forms. It uses cookies and is covered by the Microsoft Privacy Statement.
Visitors in the European Economic Area, the UK and Switzerland are asked first. Analytics cookies are only set after you agree in our consent message.
Advertising and cookies
We may show ads served by Google AdSense to keep the site free.
- Third-party vendors, including Google, use cookies to serve ads based on a user's 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 visit to this site and/or other sites on the Internet.
- You may 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.
Visitors in the European Economic Area, the UK and Switzerland are asked for consent through a Google-certified consent message before personalized ads are shown. Visitors in US states with privacy laws can opt out of the sale or sharing of personal information through the same message, and we honor Global Privacy Control signals where the law requires it.
Purchases
Paid printables are sold through third-party platforms such as Etsy or Gumroad. They process your payment and order details under their own privacy policies. We receive only what's needed to deliver your order.
If you sign up for free printables or our newsletter, we store your email address with our email provider and use it only to send what you asked for. Every email has an unsubscribe link.
Children
This site is meant for a general audience and is not directed at children under 13.
