Privacy
Last updated 2026-10-01. Maxwell International, accounts@maxwellinternational.ai.
There are no accounts, no sign-up and no cookies. You pay per request with a crypto wallet, so we never receive your name, email or card details.
What we record
| Record | What it contains | Kept | Why |
|---|---|---|---|
| Request log | IP address, country, client software and referrer as sent by your client, path, status, time | 90 days | Operations, abuse and fraud prevention, usage statistics |
| Payments | Our copy of what the public blockchain already shows (paying wallet address, amount, network, transaction id), plus which product we delivered for it | Permanently, like the blockchain itself | Accounting, proof of delivery, disputes |
| maxwell-chat (llm.chat) | Paying wallet, payment, IP address, client, the full prompt and the full answer | Permanently | Abuse review and blocking abusive wallets |
Every payment is a transaction on a public blockchain (Base or Solana). It is permanent and visible to anyone there, independent of us; our payment log is simply a record of those on-chain transactions matched to what we delivered.
Instructor listings
If you list yourself as an instructor, we store what you enter (name, age, country, what and where you teach, prices, contact details, message, optional photo), your key's fingerprint (never the key itself) and the IP address used to sign up (spam control). Your age, the IP address and your key are never published. Nothing is public until we review and approve it; once approved, the profile is sold as data to AI assistants, agents and apps worldwide, who may keep copies. You can edit or delete everything at any time with your key, or ask us to; deletion removes the profile, photo and contact details from our systems but cannot recall copies already delivered. Photos are stored with their embedded location data removed. Legal basis: your consent, given in the form.
MCP server
The hosted MCP server at https://api.maxwellinternational.ai/mcp keeps no records of its own beyond the request log and payments above. The npm package @maxwellintl/x402-mcp runs on your computer, sends no telemetry, and keeps your wallet key and your spending totals only on your computer.
Who processes data for us
Cloudflare (network and hosting edge), Coinbase Developer Platform (payment verification and settlement), and an AI model provider for maxwell-chat requests. We do not sell data and we do not use it for advertising.
Your choices
Ask about records linked to your wallet or IP address at accounts@maxwellinternational.ai. Payment records are kept as described above because they document completed transactions.
