Privacy Policy

Sienna uses account and provider authorization data to connect the Sienna CLI and approved read-only Hosted AI connections to advertising resources authorized by the user.

Sienna does not sell personal data. Provider credentials remain in Sienna's encrypted server-side vault and are used only for requested operations. They are not disclosed to Claude, ChatGPT, Notion, or another MCP host.

Hosted AI connections receive only the analytics results requested by the user. Sienna stores connection identity, granted read scopes, token hashes, job state, rate-limit counters, and security-event classifications needed to operate and protect the service. Access and refresh tokens, local CLI sessions, provider credentials, and raw query or result content are not written to application security logs. A user can revoke each Hosted AI connection independently from Sienna Setup without logging the local CLI out.

To request account or connection deletion, use the data deletion instructions at /data-deletion.
