What this website stores on your device.

The short version

The public website and journal can be read at any age without optional tracking. Google Analytics loads only after one action in which an adult visitor self-attests that they are 18 or older and allows analytics; we do not verify age. We do not use advertising cookies or Microsoft Clarity session recordings.

Preferences stored in your browser

preferred_locale is a language cookie valid for 180 days. Local storage also holds preferredLocale, languageBannerDismissed and the journal theme mp-blog-theme until you clear site data. cookieConsent stores your privacy choice, policy version, expiry and, when you use the adult analytics action, your self-attestation. That choice is valid for 180 days. No date of birth is requested. We do not verify age.

Optional Google Analytics

After one action in which an adult visitor self-attests that they are 18 or older and allows analytics, Google Tag Manager loads Google Analytics 4; we do not verify age. GA4 uses _ga and _ga_* cookies to distinguish browsers and measure page visits and interactions. These cookies normally last up to two years. Google receives technical request information, including your IP address. Our pageview events omit URL query strings and fragments. Advertising storage, ad personalisation and Google signals are disabled.

Refuse or withdraw consent

Choose Continue without analytics to refuse. To change a saved choice, open Cookie settings near the bottom of a page or on this Cookies page. Choosing Continue without analytics disables measurement, clears accessible analytics cookies and reloads the page if tracking was already loaded. This does not delete previously collected analytics data; contact us about data requests.

One choice across the website and journal

Your choice applies to this browser on www.mathandpatterns.com, including the journal. After 180 days, or when the consent policy changes, we ask again before enabling analytics. Clearing all site data, including local storage, also resets the choice. Clearing cookies alone may not reset it.

Privacy limits
