Privacy Policy

Last updated: October 21, 2026

TAINCHENG, L.L.C. operates WebExtract. We collect as little as we can.

What we store

• API keys: only a one-way hash, plus credit balance and usage counts.
• Purchases: Stripe processes card payments; we never see your card number. We keep the Stripe session ID and the email Stripe provides, to support your purchase.
• Free tier: a per-IP (IPv6: network prefix) daily call counter, deleted after the day ends.
• x402 payments: your wallet address and transaction are public on the blockchain; we don't link them to other identity data.
• Server logs: standard technical logs kept for operation and abuse prevention.

What we don't do

We don't store the pages you ask us to extract or their content beyond processing the request, we don't sell data, and we don't use advertising trackers.

Processors

Stripe (payments), Coinbase Developer Platform (x402 payment settlement), Cloudflare (network delivery), and our hosting provider.

Your choices

Contact us to ask what we hold about you or to delete it (we may keep records required for accounting and law).
