CN RegWatch (cnregwatch.com), including the China data MCP server, is operated by INTELLIFIN LIMITED. This page describes the data the site actually handles.
What we collect
Email signup: your email address is added as a contact to our list in Resend.
Pro and Team subscriptions: Stripe processes the payment, so we never see your card number. After checkout, your email and Stripe customer ID are stored on your Resend contact so we can manage the subscriber list. When a subscription ends, the contact is removed from that list.
China data MCP: a daily call counter keyed by a truncated SHA-256 hash of your IP address. If you use a key: a SHA-256 hash of the key, its first characters, your credit balance, and the email from checkout if you bought credits by card. The tool arguments you send are processed to answer the call and are not stored. We also keep an aggregate count of calls per day, per tool, marked free, paid or blocked, with no arguments, keys or IP addresses.
Credit packs: a credit ledger with the Stripe checkout session ID, or the transaction hash for USDC on Base payments, plus USDC quotes (amount, credits, key hash). Transactions on Base are public. We never ask for wallet keys or seed phrases.
Server logs: Vercel keeps request logs, and our code logs errors and credit grants (session ID or transaction hash, never card data).
Processors
Stripe: payments.
Resend: email and contacts.
Vercel: hosting and logs.
Neon: the MCP database (rate limits, keys, credits).
Cookies
The site's own code doesn't set cookies or use analytics. Stripe's checkout pages are on Stripe's domain.
Retention
Unpaid USDC quotes are deleted about a day after they expire. We haven't set automatic deletion periods for other data. To request access or deletion, email support@rendlet.com.
