Privacy Policy — Japan Payments MCP

Last updated: 2026-07-08

Summary: this service is stateless and stores nothing. There is no database. No account system. No cookies. No analytics scripts.

What the service processes

Japan Payments MCP is a stateless translation layer between AI agents and the Japanese payment gateway KOMOJU. When a tool is called, the request parameters — order amounts, descriptions, an optional buyer email, and your bring-your-own KOMOJU secret key sent as an HTTP header — are used in memory only to authenticate and forward a request to KOMOJU, and are discarded when the response is returned.

What is stored

• Nothing at the application layer. No orders, no credentials, no user records are written anywhere. A payment link is KOMOJU's own hosted-page URL, returned as-is — the server keeps no copy.
• Standard infrastructure logs. The service runs on Vercel, which keeps short-lived HTTP request logs (IP address, path, status) for operations, per Vercel's privacy policy. Credential headers are never logged by the application.

Where money and personal data actually flow

Funds always flow buyer → KOMOJU → merchant, directly. Buyer payment details (card numbers, konbini codes, bank info) are handled on KOMOJU's own hosted checkout pages and never pass through this service. Data submitted to KOMOJU is governed by KOMOJU's privacy policy.

Third parties

The only third parties that receive data are the payment gateway (KOMOJU) and our hosting provider (Vercel). No data is sold or shared with anyone else.

Your choices

Because nothing is stored, there is nothing to delete or export. Stop sending requests and no trace of your usage remains at the application layer.
