Space Kitty Archive has no accounts, no advertising, no analytics scripts and no tracking cookies.
Requests
Like any website, requests pass through Cloudflare, which processes IP addresses and request metadata to deliver the site, protect it from abuse and enforce rate limits. Operational logs are short-lived.
Payments
Paying with x402 is an on-chain USDC transfer. We record the settlement transaction hash, the paying wallet address, the resource purchased and the time, to provide receipts and handle disputes. Blockchain transactions are public by nature. If you pay in the browser, your receipt is kept only in your browser's local storage.
Scholarly metadata
Paper and trial records include author and sponsor names as published in public scholarly databases (arXiv, OpenAlex, Europe PMC, ClinicalTrials.gov). We process them to index and cite the literature. To request a correction or removal, contact us.
