What you type into the calculators
Course names, letter grades and credit hours are processed entirely in your browser using JavaScript. That information is never transmitted to us and never stored on any server we control. To keep your work from disappearing when you refresh, it is saved in your browser's local storage, which is a private area on your own device. Clearing it with the clear button on any calculator, or clearing your browser data, removes it permanently. We have no technical means of retrieving it.
Information collected automatically
Like most websites, our hosting produces standard server logs containing the requesting IP address, the page requested, the time of the request and the browser's user agent string. These are used to keep the site running and to investigate faults. We may also collect aggregate statistics about which pages are visited and what type of device is used, in order to understand which tools people find useful. None of this is combined with anything you enter into a calculator.
Advertising, cookies and third party vendors
This site is supported by advertising. Third party vendors, including Google, use cookies to serve ads based on your prior visits to this website or to 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 other sites on the internet.
You may opt out of personalised advertising by visiting Google's Ads Settings page. Third party vendors and ad networks other than Google may also serve advertisements on this site, and you can visit the Network Advertising Initiative opt out page to opt out of some of those vendors' use of cookies for personalised advertising.
Where required by law, visitors in the European Economic Area and the United Kingdom are shown a consent notice before personalised advertising cookies are set, and consent can be changed or withdrawn at any time through that notice. You can also block or delete cookies through your browser settings. Doing so does not affect the calculators, which run entirely on your device.
Children
The calculators are aimed at students, including those under eighteen. We do not knowingly collect personal information from anyone, and because no account is required and nothing you enter is transmitted to us, there is no personal data for us to hold. If you believe a child has somehow submitted personal information through this site, contact us and we will investigate.
Your rights and choices
Because we do not hold personal data that identifies you, there is generally nothing for us to hand over, correct or delete on request. If you are covered by the GDPR or the CCPA and wish to make an enquiry about your data, write to us and we will respond within the timeframe those rules require.
Changes to this policy
If this policy changes, the revised version will be posted on this page with a new date at the top. Continuing to use the site after a change means you accept the updated policy. Questions can go to the address on our contact page, and the limits of what this site can tell you are set out in the disclaimer.
