Privacy.

numra-rs.org uses Cloudflare Web Analytics for traffic measurement. No cookies, no fingerprinting, no third-party trackers, no advertising network beacons.

What is collected.

Anonymous request metadata only: page URL, referrer, an approximate country, and a coarse browser/OS class. The information is collected and aggregated by Cloudflare; no identifier links a visit to a specific person or device.

What is not collected.

• No cookies are set by this site.
• No browser fingerprinting.
• No IP addresses are stored.
• No third-party advertising or marketing trackers.
• No Google Analytics, no social-media pixels.

Where data is stored.

On Cloudflare's edge infrastructure, retained for at most six months in aggregate form. See Cloudflare Web Analytics documentation for the underlying retention policy.

Removal requests.

Because no identifiable data is collected, there is no record to remove. If you want to confirm this for compliance reasons, email [email protected] with the subject prefix [Numra privacy].

Other Numra properties.

The same policy applies to book.numra-rs.org, docs.numra-rs.org, and examples.numra-rs.org. The book and examples properties run on the same Cloudflare Pages stack and inherit the same privacy posture.
