Cookie Policy

What this site uses

Strictly necessary. The locale you select may be remembered so that the site serves the language you chose rather than repeatedly sending you to English. This is functional and carries no tracking identifier.

Local storage — not a cookie. Course progress is kept in your browser's local storage under a single key. It never leaves your device and it is not sent with any request.

Analytics. This site uses Google Analytics 4 to count page views and see which lessons people actually read. It runs under Google Consent Mode with every storage category set to denied before the tag loads, so nothing is written to your device unless you choose "Allow" on the banner. If you decline, or simply ignore the banner, measurement continues without cookies and without an identifier: we can see that a page was read, not who read it.

What is sent, in every case, is limited by a fixed allow-list in the site's code — a page path, a language, and a small set of named events such as "a lesson was completed" or "a calculator was used". The list of permitted properties is defined per event, and anything not on it is dropped before the request is made. Figures you type into the calculators are never sent anywhere: they are computed in your browser and stay there.

You can change your answer at any time by clearing this site's data in your browser, which brings the banner back.

Cloudflare Web Analytics. The site is served through Cloudflare, which also counts page views and visits for us. It uses no cookies, no local storage and no fingerprinting, so it cannot recognise you across pages or visits; it records the page, the referring site, the country and the browser type, and we only ever see totals. Because it stores nothing on your device it runs whatever you choose on the banner.

Live market data. Price and sentiment figures are read directly from CoinGecko and alternative.me when you open a page that shows them. Those requests reach those providers from your browser and are subject to their own policies. They set no cookies for us.

What this site does not use

• Advertising or retargeting cookies — Google Consent Mode's advertising categories are hard-coded to denied and are never lifted, including for readers who accept analytics
• Social media tracking pixels
• Cross-site tracking of any kind
• Session recording or heatmap tools
• Third-party fonts

Managing them

You can clear cookies and site data from your browser settings at any time. Clearing site data will remove your saved course progress, because that progress exists only in your browser.

Blocking storage entirely will not break the site. Progress tracking simply stops persisting, and every read is wrapped so that a blocked or unavailable store fails silently rather than breaking a page.
