# Site knowledge index

Public website read access is open to AI agents, search engines and research crawlers. No account, API key or special user agent is required.

- [About the product](/knowledge/about.md)
- [Calculator formulas and limits](/knowledge/calculator.md)
- [Companion app facts](/knowledge/app.md)
- [Privacy summary](/knowledge/privacy.md)
- [Agent access policy](/knowledge/agent-access.md)

The verified date records the last source/content check, not a last-crawl or deployment time. The resource field identifies the authoritative human-readable page, relative to the site origin.
