Cookie Policy
Which cookies this site uses, what they do, and how to turn them off.
Last updated: 12 May 2026
This Cookie Policy is part of, and should be read with, our Privacy Policy. It explains how Math Playground (https://math.calcstack.co) uses cookies and similar technologies.
What are cookies?
Cookies are small text files stored in your browser by a website you visit. “Similar technologies” include things like localStorage, pixels and web beacons. They let a site remember information between page loads or visits — and let advertisers and analytics tools measure activity.
Categories of cookies we use
- Strictly necessary. Needed for the Site to work (e.g. security, load balancing) and to remember basic preferences such as your light/dark theme. These don't track you across sites and can't be switched off via a banner.
- Analytics / performance. Help us count visits and see which pages are useful, in aggregate (e.g. Vercel Analytics). They are not used to identify you personally.
- Advertising. If ads are shown, third-party networks — including Google AdSense — may set cookies (such as Google's DoubleClick/DART cookie) to serve and measure ads, and, with consent where required, to personalise them based on your visits to this and other sites.
Third-party cookies
Some cookies are set by third parties we use, not by us directly — mainly our analytics and advertising partners. Their use of cookies is governed by their own policies, for example:
- Google (AdSense / advertising): policies.google.com/technologies/ads
- Google Privacy & Terms: policies.google.com/privacy
How to control cookies
- Consent banner. Where required (EEA, UK and similar regions), we ask for your consent before setting non-essential cookies, and you can change your choice at any time.
- Browser settings. Every major browser lets you block or delete cookies — see your browser's help pages. Blocking all cookies may break some features.
- Ad personalisation. Turn off personalised Google ads at adssettings.google.com; opt out across many vendors at aboutads.info/choices and optout.networkadvertising.org.
Changes
We may update this Cookie Policy as our tools change. The “Last updated” date above reflects the latest version.
