A plain-language account of what this site processes and why. It's a personal portfolio project, not a commercial service, and it's built to collect as little as possible.
Just browsing the site sets no cookies, runs no analytics or trackers, and loads no third-party fonts or scripts that would expose your IP — the fonts are served from this domain. Standard web-server access logs (including IP address) may be kept briefly for security and abuse prevention, on the basis of legitimate interest.
If you ask the agent a question, that request is processed to answer it:
| Data | Purpose & handling |
|---|---|
| Your question | Sent to the retrieval pipeline and to a large-language-model provider to generate a grounded answer. Please don't enter personal or sensitive information — it isn't needed to ask about the science. |
| Model provider | Generation runs on a third-party, OpenAI-compatible LLM API via OpenRouter (the model is selectable — e.g. Qwen, Llama, or Ai2's OLMo), which may process the request outside the EU. Responses are scrubbed for personal identifiers before they're returned. |
| IP address | Used transiently for per-IP rate-limiting and abuse prevention (legitimate interest). Not used to profile or track you across sites. |
| Session id | A random identifier generated fresh on each page load, held in memory to thread a single conversation. It is not a persistent cookie and does not identify you. |
Map tiles are requested from Esri's imagery service when you view a map; your browser contacts them directly, as it would for any embedded map.
Under the GDPR you can request access to, correction of, or erasure of any personal data held about you, and you may object to processing or lodge a complaint with a supervisory authority. Because the site keeps essentially no identifying records, there is usually nothing to retrieve — but if you have a question or a request, contact joshua.dell@outlook.com.
