We do not set any analytics, advertising, or cross-site tracking cookies from our own domain.

Local storage (not cookies but similar)

Your browser’s localStorage holds the state of your Bonus Portfolio Builder (which bonuses you have picked, the deposit and volatility you set). This data never leaves your device. Clearing your browser storage discards it.

Partner sites

Once you click a rel="sponsored" affiliate link and land on a casino operator’s site, that operator sets its own cookies according to its own privacy policy. We are not the controller of those cookies; check the operator’s cookies page.

How to control cookies

  • Reject preference cookies: use your browser’s private/incognito mode. Nothing on CasiMath breaks.
  • Delete existing cookies: your browser’s settings under Privacy / Site data. Look for casimath.com and clear.
  • Global control: aboutcookies.org has step-by-step instructions per browser.

Do Not Track

If your browser sends the DNT (Do Not Track) header we already do not run any analytics, so nothing needs to change on our side. Our behaviour is the same with or without DNT.

Changes

Updates to this policy — including any new cookie we introduce — will bump the updated date at the top and be surfaced with a footer notice for at least 30 days.
