CoMath.ai uses minimal cookies and browser storage to make the site work. We do not use advertising cookies or track children across websites. Here's exactly what we use and why.
What Are Cookies?

What We Do NOT Use
CoMath.ai does not use:
❌ Google Analytics or advertising cookies ❌ Facebook Pixel ❌ Third-party tracking cookies ❌ Persistent login cookies ❌ Any cookies that track children across other websites
📍 Location Information
The "general location (country/region)" mentioned in our Privacy Policy comes from Cloudflare's server-side request logs — not from cookies and not from your browser's geolocation API. Specifically: when your browser connects to our servers, the IP address is automatically logged by Cloudflare for security and abuse prevention. From this IP address, only the country and region can be approximately determined (never a precise location). This data is held by Cloudflare under their privacy policy and is not stored in cookies on your device.
