Privacy Policy

Last updated October 15, 2026.

This policy explains what CHT Web, LLC ("we") collects when you use Counterparty Check.

What we don't keep

We do not store the contents of check requests: the names, emails, domains, addresses, bank or wallet details you submit are used to run the check and then discarded. Each response includes a signed receipt containing a one-way fingerprint (SHA-256 hash) of your request, so you can later prove what was checked without us keeping it.

What we do keep

• Usage records: the time of each call, the endpoint, the payment method, the amount charged and the verdict.
• API keys: stored only as one-way hashes, with their balance and status.
• Purchases: Stripe's references for card purchases (session and payment IDs, amounts). Card numbers are handled by Stripe and never reach us.
• Per-call crypto payments: payment references such as wallet addresses and blockchain transaction IDs, which are public on the blockchain.
• Technical data: IP addresses are used briefly in memory for rate limiting. Our hosting provider may keep standard server logs.

Who processes data for us

Stripe (card payments), Coinbase and other x402 facilitators (per-call payments), our hosting provider, and the public data sources queried during a check (domain registries through RDAP, and DNS resolvers operated by Cloudflare and Google). Domain names you submit are sent to those registries and resolvers to perform the check.

What we don't do

We do not sell personal information, use it for advertising, or set tracking cookies. The only cookie is a short-lived one that lets the browser you paid with see your new API key.

Retention and your choices

Usage and purchase records are kept as long as needed for accounting, tax and dispute purposes. To ask about or delete data associated with your API key, email chtwebllc@gmail.com.
