certs.lol does not collect personal data. There are no accounts, cookies, third-party analytics, tracking pixels, or third-party scripts.
Cloudflare processes requests as our CDN and compute provider. Their standard edge logs (IP, URL, timestamp) are subject to Cloudflare's privacy policy. We do not access, store, or process these logs.
We store an IP-derived counter in a Cloudflare Durable Object for rate limiting. These counters expire automatically and contain no personally identifiable information beyond a hashed IP key.
TLS scan results are cached for 6 hours to improve performance. Cached data is keyed by the submitted target and contains only publicly observable TLS configuration — no private information.
We keep aggregate counters for service health: scan totals, cache hits and misses, errors, and rate-limit events. These counters do not include requested domains, IP addresses, or per-request identifiers.
