Privacy Policy

Last updated: 2026-10-09

1. Who is responsible

TSUNAGI (Kazuhiro Muto, sole proprietor, Japan; "we"). Contact: mxstage@tsunagi.app.

2. The MX Stage software

MX Stage runs on your computer. It connects to the Maximo you choose and to the AI assistant you use, and to other hosts only in the cases below. If you turn on automatic updates (Settings → Updates; off by default), it also asks GitHub once a day for the latest version number; nothing about you or your data is sent with that request, and GitHub's privacy statement applies to it. Installing an update downloads the new version from GitHub and its packages from the npm registry. Only when you press Download data and connect in Settings → Demo, it downloads fictional demo data we serve on Cloudflare (mxstage-demo.pages.dev) once; nothing is sent to us, but Cloudflare processes technical data such as IP addresses to deliver it. It does not send your Maximo data, your Maximo API keys, your prompts or usage data to us, and it has no telemetry. License keys are checked on your computer without contacting us. What your AI assistant does with the data you give it is governed by your agreement with that AI provider.

3. This website

This website uses Cloudflare Web Analytics to count which pages are viewed and where visitors come from. It uses no cookies, does not track individual visitors and does not record anything after the "?" in a URL. We do not use advertising and do not set cookies of our own. It is hosted by Cloudflare, which processes technical data such as IP addresses to deliver and protect the site. When you open the checkout, Paddle loads its checkout and may set its own cookies; see Paddle's privacy policy.

4. Information we receive when you buy

Paddle.com, our Merchant of Record, processes your payment. We never see your card details. We receive: your name or organization name, email address, country, the production Maximo URLs you enter, and order and subscription identifiers. We use this information to issue and renew your license key, send it to you by email, provide support, prevent misuse, and keep the records required by tax and accounting law. We do not sell it or use it for advertising.

5. Inquiries and partnership

When you contact us, or sign a partnership or advisory contract with us, we receive contact details such as your name, company and email address, and use them to reply, contract and invoice. If you ask about using MX Stage for your own Maximo, we may introduce a partner company that can take on the project; we pass your contact details and inquiry to that partner only after you agree. We do not take on project work, so we do not receive your Maximo data.

6. Service providers

• Paddle.com — payment, invoicing, tax (Merchant of Record)
• Cloudflare — website hosting, the license database and the demo data
• Resend — sending license emails
• Google Workspace — our support mailbox

These providers may process data outside your country, under their own safeguards for international transfers.

7. How long we keep it

We keep license records while your license is active and afterwards for as long as tax and accounting law requires (in Japan, generally 7 years). Emails to support are kept while needed to help you.

8. Your rights

You can ask us to access, correct or delete your information, or object to how we use it, by emailing mxstage@tsunagi.app. We may need to keep some records that the law requires. You can also complain to your data protection authority.

9. Changes

We will post changes to this policy on this page and update the date above.
