Privacy
Math Questions Hub is designed to need as little of your data as possible. No account, no tracking of what you personally type, and nothing you enter into a tool is processed on a remote server. The site is free and supported by advertising, which is explained in the Advertising section below.
What's processed locally, not on a server
Problems typed into the solver or calculators, and worksheet generation, all run entirely in your browser using JavaScript. None of that content is sent to us or to any third party. Closing the tab discards it.
What's stored on your device
Practice history, accuracy by topic, and ruler calibration settings are saved using your browser's local storage, a standard web feature that keeps data on your device only. This lets your progress persist between visits without an account. Clearing your browser's site data removes it completely, and it never leaves your device in the meantime.
What we don't do
- We don't require an account or collect names, emails, or personal identifiers to use any tool.
- We don't sell your data, and we never see the problems you solve or your practice history.
- The only third parties that receive data from your visit are Google (for analytics and advertising), as described below.
Analytics
We use Google Analytics to understand which tools and guides are useful and where the site is slow: aggregate data like page views, general location by country, and device type. This data isn't tied to the math problems you solve or your practice history, which never leave your device (see above). If you are in the European Economic Area, the United Kingdom, or Switzerland, analytics only runs after you give consent through the consent message described below. Google's own use of this data is governed by the Google Privacy Policy, and you can opt out of Google Analytics tracking generally usingGoogle's browser add-on.
Cookies and your choices
Analytics and advertising rely on cookies and similar technologies. How we handle them depends on where you are:
- European Economic Area, United Kingdom, and Switzerland: a consent message from Google appears on your visit. Analytics and advertising cookies stay off until you choose to accept them, and you can change or withdraw your choice at any time through the privacy settings link or button the message provides.
- Everywhere else: analytics and advertising cookies are enabled by default, and no banner is shown. You can control them using the options listed in the Advertising section below, or through your browser's cookie settings.
Declining or blocking cookies doesn't limit any tool on the site; every solver, calculator, and practice feature works the same either way. If you decline, ads may still appear, but they won't be personalized.
Advertising
Math Questions Hub shows ads through Google AdSense, which helps keep the site free. Google and its advertising partners use cookies and similar identifiers to serve and measure ads, and, where permitted and not declined, to show ads based on your visits to this and other websites. Ads are not shown on this privacy page.
We don't give advertisers any information about you, and the content of your math problems is never part of this process because it never leaves your browser.
