Privacy first
We minimize collection and keep calculator, tool, favorite, recent, and draft data on your device wherever practical.
Security
Managed HTTPS infrastructure, limited data movement, dependency maintenance, and a responsible disclosure channel reduce avoidable risk.
AI transparency
Mocked, rules-based, and future AI-generated output should be distinguishable. AI assists decisions; it does not become the authority.
Local storage
Phase 1 workspace data uses browser-local `ds.*` keys. Clearing site data removes it, and anyone sharing the browser profile may access it.
Data sources
Material methods and assumptions are explained, external sources should show freshness, and AI explanations are never treated as primary sources.
User control
No login wall is required for exploration. You can clear local data, avoid optional transfers, verify results, and choose whether to act.

Our legal hub covers privacy, security, AI disclosure, data sources, acceptable use, and accessibility in detail.
