Privacy Policy

1. Overview

This policy covers this website ("the Site"), operated by Ludo Technologies Inc. ("we", "us"), a company headquartered in Kanagawa, Japan. The Site is informational: it documents the polyscan open source analyzers and related projects.

There are no accounts and nothing to sign up for. The analyzers themselves — pyscn, jscan, and the shared core module — run entirely on your own machine or CI runner. We never receive your source code, your analysis results, or the names of the projects you analyze.

2. Information we process

• Usage analytics. When analytics are enabled, we use Google Analytics to understand which pages are visited and how visitors arrive. This uses cookies and processes technical details such as your IP address, browser, device type, referring page, and the pages you view. We use it only in aggregate, to decide what to document next.
• Hosting logs. The Site is hosted on Vercel, which records standard request logs — IP address, user agent, requested path, timestamp — for delivery, security, and abuse prevention.
• Email you send us. If you contact us, we process your message and your email address in order to reply.

We do not sell personal information, and we do not use it for advertising or profiling.

3. Third-party services

The Site relies on a small number of providers that process data on our behalf or as independent controllers: Vercel (hosting) and Google Analytics (usage measurement). Web fonts are self-hosted at build time, so loading a page makes no request to a font CDN. Links to GitHub, PyPI, and npm are ordinary outbound links — once you follow one, that site's own privacy policy applies.

These providers may store data outside Japan, including in the United States, and are bound by their own terms and privacy policies.

4. Cookies

The Site sets no cookies of its own. Analytics cookies are set only when analytics are enabled. You can block or delete them in your browser, or install the Google Analytics Opt-out Browser Add-on. The Site works normally without them, and we never use cookies for advertising.

5. Retention

Analytics data is retained according to the retention period configured in Google Analytics. Hosting logs are retained for the period set by our hosting provider and then rotated out. Email correspondence is kept as long as needed to handle your enquiry and to keep a record of it.

6. Your rights

Depending on where you live, you may have the right to request access to, correction of, or deletion of personal information we hold about you, and to object to certain processing. Because the Site holds so little, such a request will usually concern analytics data or email correspondence. Contact us at the address below and we will respond within a reasonable period.

7. Children

The Site is intended for software developers and is not directed at children. We do not knowingly collect personal information from children.

8. Changes

We may update this policy as the Site changes. The "last updated" date above always reflects the current version. If we add a feature that processes materially more information, we will say so here before it launches.
