FAQ

Short answers to common questions.

#Do agents change my data without asking?

No. Agents propose; you approve. See agents and the Inbox.

#Where is my data stored?

As Parquet on DuckLake, in a Cloudflare R2 bucket belonging to your instance. See security.

#Which models do the agents use?

Claude. Routine agents use Haiku 4.5; analysis and transformation use Sonnet 5.5. A workspace spend cap applies; when it is reached, agent runs stop until the window resets.

#Can I write SQL myself?

Yes, in Data Studio, with the same guard the agents use.

#Can I export or leave?

Everything is in open formats: Parquet, a SQLite catalog and plain-text SQL and documents. Lineage exports as OpenLineage; the semantic layer as JSON-LD or YAML.

#How do I try it?
