Cookie Policy

Session cookies: keep you signed in after you log in. Membership features do not work without them.

The browser's local storage holds small records to show the welcome message only once, avoid losing a draft forum/blog post, and keep chart data you entered without signing in on that device.

These records are never sent to the server; they are deleted when you clear your browser data.

Google Analytics 4 (GA4): used to understand how pages are used and to spot performance issues. Without measurement consent, GA4 cookies (_ga, _ga_*) are not written and measurement signals are sent as denied via Google Consent Mode.

GA4 cookies are stored in your browser for up to 24 months; you can withdraw consent at any time.

This site serves ads through Google AdSense. Google and third-party vendors may use cookies and similar technologies to serve, cap and measure ads.

Google's use of advertising cookies, including the DoubleClick DART cookie, enables it to serve ads based on your visits to this site and other sites on the Internet.

In the European Economic Area, the United Kingdom and Switzerland these cookies only run after you give consent. Without consent, ads are shown non-personalised.
