Last updated June 9, 2026
A cookie is a small file a website stores in your browser. Mad Brain uses cookies sparingly. Nothing optional loads until you choose to accept it through our consent banner.
What cookies we set
These are essential and always active, because the site needs them to work.
- Consent preference— remembers your cookie choice so we don’t ask on every visit.
- Theme preference— remembers whether you use light or dark mode.
What third parties set
These load only after you opt in. If you decline, they never run.
- Google Analytics or Plausible— measures which pages are useful. Loads only with your analytics consent.
- Vercel Analytics— basic, privacy-friendly traffic measurement. Loads only with your analytics consent.
- Google AdSense— used only on free tool pages under /tools. Loads only with your marketing consent.
How to opt out
You are always in control.
- Change your choice any time using the cookie banner, or by clearing your saved preference.
- Block or delete cookies in your browser settings. The site still works, though some measurement stops.
Changes to this notice
We may update this notice as the site grows. When we do, we will revise the “Last updated” date at the top of this page.
