# Privacy

Short and honest. Not a generic template.

## Controller

Len P. van der Hof (legal name Leendert Pieter van der Hof), Zwijndrecht, the Netherlands. Contact: Len@LPH98.ventures.

## This site

The site is a static Astro publish. Hosting and CDN may keep request logs (IP, user-agent, path, timestamp) for security and performance.

There is no newsletter backend and no contact form that sinks into a database. Mail to Len@LPH98.ventures goes to Len.

## Desk companion

Some pages show an Ask lamp. It posts same-origin to /api/companion. The browser never holds an NVIDIA token.

A Node process on the server (loopback only) calls NVIDIA NIM. Default rate limit is about 60 requests per minute per IP. Body cap about 48k.

Payload may include job, question, language, path, title, and optional excerpt/selection/history. Answers are grounded on the site catalogue; unknown URLs are dropped.

Do not put sensitive personal data or medical records into the companion. It is a page helper, not a care provider.

## Cookies and tracking

No first-party marketing cookies are claimed here. A CDN or third-party analytics may set their own; check your browser. No invented cookie inventory.

## Your rights (GDPR)

You may ask for access, correction, erasure, restriction, objection, or portability where applicable. Email Len@LPH98.ventures. Complaint: Autoriteit Persoonsgegevens (NL).
