Privacy Policy

No accounts, no server-side storage of your calculations. Every calculator on JustCalculateThis runs entirely in your browser. The values you type are not transmitted to us and are not stored on a server.

Information stored on your device

The only information JustCalculateThis keeps is stored locally in your browser (local storage) and stays on your device. It is used purely to remember your preferences:

• Your theme preference (light or dark)
• Any favourites or recently used calculators you save
• Optional calculation history — removable entry by entry or all at once

You can erase all of it at any time from your browser's site settings. Nothing you enter into a calculator is ever sent to us.

Server log files

Like most websites, our hosting provider may record standard log data when you request a page. This typically includes your IP address, the date and time of the request, the page requested, the referring page, your browser type and version, and your operating system. This information is used in aggregate to keep the site running, diagnose errors, and prevent abuse, and it is not used to identify individual visitors.

Cookies, web beacons and advertising

JustCalculateThis may display advertising to keep the calculators free. Advertising may be served by third-party vendors, including Google, and those vendors may place and read cookies, use web beacons (also called clear GIFs or pixel tags), use device identifiers, and collect non-personally identifying information such as your IP address, approximate location, device and browser information, and the pages you view on this and other websites, in order to measure advertising and serve more relevant ads.

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. Third-party vendors and ad networks operate under their own privacy policies, which we do not control. You can review how Google uses data from sites that use its services atpolicies.google.com/technologies/partner-sites.

Your choices and how to opt out

You are always in control of advertising cookies:

• Opt out of personalised advertising from Google atGoogle Ads Settings.
• Opt out of many third-party vendors' cookies atoptout.aboutads.info andyouronlinechoices.com.
• Block or delete cookies in your browser settings; calculator functionality works without them.
• Where required by law (for example in the European Economic Area, the United Kingdom, and Switzerland), we ask for your consent before setting non-essential advertising cookies, and you can change or withdraw that consent at any time.

Analytics

We may use privacy-respecting, aggregate analytics — such as page-view counts — to understand which calculators are useful. This never includes the values you enter into any calculator.

Children's privacy

JustCalculateThis is a general-audience utility site and is not directed to children under 13. We do not knowingly collect personal information from children.

Changes to this policy

We may update this policy as the site or the applicable rules change. The "last updated" date at the top of this page reflects the current version.
