Privacy

Short, because there is very little to say. This site collects nothing.

What is stored about you

Nothing. There is no account, no login, no newsletter, no contact form and no comment box. The numbers you type into a calculator stay in the memory of your own browser tab and are gone the moment you close it. They are never sent to a server, because there is no server here doing anything other than handing you these files.

Your ZIP code

If you type a ZIP code into the where to buy box, it is used in your browser to build a Google Maps search link, and it is placed in that link only when you click it and go to Google. It is not stored, not logged and not sent anywhere by us. The site never asks your browser for your location.

Cookies

This site sets no cookies of its own and uses no local storage of its own. Google AdSense, described under Advertising below, does set cookies in your browser, and that paragraph says what they are for and how to turn the personalised part off.

Third parties

Apart from the Google AdSense script described below, the page loads only files from this domain. There is no web font, no tag manager, no chat widget and no analytics or tracking pixel. The only outbound links are the where to buy links, which go to Google Maps, and the source links, which go to the publishers cited on each page. Once you follow a link you are on their site and their policy applies.

Advertising

This site uses Google AdSense to serve advertising. Third party vendors, including Google, use cookies to serve ads based on your prior visits to this site and to other sites on the web. Google's use of advertising cookies enables it and its partners to serve ads to you based on that history. You can turn personalised advertising off at Google Ads Settings, and you can opt out of personalised advertising from many other vendors at aboutads.info. Turning it off does not remove advertising, it removes the personalisation. If you are visiting from the European Economic Area, the United Kingdom or Switzerland, Google is required to obtain your consent before setting a personalised advertising cookie, and it does that through its own consent message rather than through anything this site builds. If you decline, advertising can still appear, but it is not personalised. Google's own description of how it uses data from sites that use its services is at policies.google.com/technologies/partner-sites.

Children

This site is a set of arithmetic tools and is not directed at children, and since it collects nothing it collects nothing about them either.
