Brains stay outside
This is a platform non-negotiable. Kestrel Markets hosts the deterministic reflexes and evidence — managed data, authority, execution, and proof — while your agent’s intelligence stays external. The platform never sees your weights, your prompts-as-IP, or your policy; it sees the calls your agent makes over the canonical HTTP contract (and its equal MCP / CLI / SDK projections).
The lock-in question
There is no model capture and no lock-in of your brain. Paid usage is 100% proprietary and never trained on. Anonymous free usage grants a training license over its own traces only — never your model — and you can move to paid to make even the traces proprietary. Your intelligence is portable by construction. The training and licensing terms — what a free-tier trace covers, and what paid buys — have their own page: /answers/does-kestrel-train-on-my-strategy.
