Privacy

Nothing you type is stored. Colors you submit are processed in memory and discarded when the response is sent. They are never written to storage, logs or analytics, and ContrastKit makes no network requests.

What is kept:

• Daily visitor count: a one-way hash of your network address combined with a secret salt and the date, used only to count unique daily visitors (visits to the homepage and use of the API and MCP endpoint; not health checks, docs or our own monitoring). The address itself is never stored, the hash is not linked to any color you submit, and it expires after 9 days. Counting stops after about 1,000 new visitors per day per Cloudflare server instance (isolate), so daily counts are approximate.
• Rate limits: per-minute limits are counted by Cloudflare's rate limiter, keyed by network address, and are not stored by ContrastKit.

No cookies, no trackers, no analytics scripts.
