Short version. Luckyman serves public market data. We collect no account data because there are no accounts. Anonymous request metadata (rate-limit keys, optional client tags) is kept briefly for abuse prevention and aggregate analytics. Nothing you can be personally identified by is sold, ever.
1. Who we are
Luckyman Data (“Luckyman”, “we”) is operated by LocalThink Inc. This policy covers the web interface and public API at mcp.luckyman.app. For questions, contact the operator via localthink.ai.
2. What we collect
- Request metadata. IP-derived rate-limiting keys, timestamps, requested symbols, and the optional
X-LM-Clienttag (“ios”, “agent”, or “web”). Used for fair-use enforcement and anonymous, aggregate usage analytics. - No accounts, no profiles. The public API requires no registration, so we hold no names, emails, or payment details.
- AI agents. When an AI agent connects on your behalf, that agent — not Luckyman — holds your credentials. We never receive your logins, passwords, or brokerage sessions.
3. Upstream data
Luckyman normalizes and redistributes data from public upstreams (Yahoo Finance, CBOE, SEC EDGAR, and free FX/crypto sources). Those providers receive your requests as part of serving data; their own policies apply on their premises.
4. Retention
Aggregated analytics are kept in roll-up form; raw request records age out on a rolling basis. Rate-limit counters are short-lived by design.
5. Your choices
- Query without the
X-LM-Clientheader to skip the optional analytics tag. - Agents can cache responses to reduce repeat requests — the public cache headers tell them how.
6. Changes
Material changes will be reflected on this page with a new “last updated” date.
