## FAQ

**What am I paying for?** Movement, not the engine. Indexing, retrieval,
agent skills, and the MCP server are free forever. Paid plans add hosted
sync across machines (Pro) or across a team (Team).

**Do you train on my sessions?** No. Never.

**What happens if I cancel?** Local memory keeps working — it never depended
on us. Synced data is exportable as markdown and JSON.
