SStockFi Pay with x402

Legal

Privacy Policy

Effective November 12, 2026.

This policy explains how Only Buy Bitcoin LLC (“we”, “us”) handles information when you use StockFi at stockfi.trade (the “Service”). StockFi has no accounts, no sign-in, no cookies and no advertising or analytics trackers.

What we process

  • Request data. The query you send (a token address or ticker, side, size, or a wallet address for Reopen Risk). Wallet addresses are public blockchain identifiers; we use them only to read that wallet's public Longbow positions for your request.
  • Payment data. The x402 payment authorization you sign, which includes your paying wallet address, the amount and a one-time nonce. Settled payments are recorded publicly on Robinhood Chain, which we cannot change or delete.
  • Technical logs. Our hosting provider, Cloudflare, processes IP addresses, user agents, request paths and timing to deliver the Service, protect it from abuse and show us errors. We keep operational logs for a short period and do not use them to build profiles.
  • Email. If you write to contact@stockfi.trade, we receive your email address and message and use them to reply.

We do not collect names, government IDs, location or jurisdiction information, and we do not sell or rent personal information.

Who else processes it

  • Cloudflare hosts the website and APIs and forwards email.
  • x402Fi (operated by us) verifies and settles payments through its public facilitator, which submits the payment to Robinhood Chain.
  • Data sources receive the requests needed to answer you: the Robinhood Stock Token API (ticker lookups), RPC providers for Robinhood Chain (onchain reads, which may include the token or wallet address) and Longbow's public read interface (the wallet address, for Reopen Risk).
  • Anthropic processes the figures for the optional prose summary in the weekend report. We send only computed market names and numbers, not your wallet address or IP address.
  • Google Fonts serves the site's typefaces, so your browser contacts Google when you load a page.

Your choices and rights

You can use the APIs without visiting the website. Depending on where you live, you may have rights to access, correct or delete personal information we hold, or to object to its use. Onchain records cannot be deleted by anyone. To make a request, email contact@stockfi.trade.

Security and retention

We never hold your keys or funds. We keep only what we need to run and secure the Service and delete logs on a rolling basis.

Children

The Service is not intended for anyone under 18.

Changes

We may update this policy and will change the effective date above.
