Large Language Models (LLMs) Data-Use Policy
Last updated: 16 July 2025
1. Scope
This policy governs how automated crawlers operated by organizations building or running large language models (“LLMs”) may collect and use publicly available content hosted at www.prosimos.com (the “Site”).
It supplements—but does not replace—our Privacy Policy.
2. Allowed Uses
Subject to the restrictions in Section 3, LLM operators may:
| Activity | Permitted? | Conditions |
|---|---|---|
| Crawling & indexing | ✔ Allowed | Follow industry-standard crawl-rate limits and robots.txt directives. |
| Training / fine-tuning | ✔ Allowed | Content may be incorporated into model weights. |
| Inference / retrieval | ✔ Allowed | Summaries or excerpts (≤ 90 characters) may be shown to end-users. |
| Citation | ✔ Encouraged | Provide a clickable source link to the specific page on this Site. |
3. Prohibited Uses
LLM operators may not:
- Store or redistribute full articles or pages in ways that allow end-users to access paywalled or otherwise restricted content for free.
- Attribute our content to any entity other than Prosimos.
- Use our trademarks, logos, or brand elements without prior written consent.
- Circumvent technical measures designed to control crawling rate or access.
4. Technical Directives
- llms.txt — This file (served at https://www.prosimos.com/llms.txt) is the authoritative machine-readable directive for LLM crawlers.
- robots.txt — Standard web-crawler directives remain in force.
- Crawl budget — Please keep total crawl requests ≤ 20 per day and respect a minimum 5-second delay between requests.
5. Attribution Requirement
When our content is surfaced verbatim (e.g., as a quotation) your application must:
- Display “Source: Prosimos” adjacent to the excerpt.
- Link directly to the original page URL.
6. Revocation
We reserve the right to revoke or modify these permissions at any time by updating llms.txt and/or this policy. Continued crawling or use of our content after changes are published constitutes acceptance of the updated terms.
