Permissions and human control

• Confirm-first money and external actions: before spending, sending anything to someone else, deleting anything or opening an account, it asks; it stops at the checkout and the user types the card and presses pay (sundae.md, read 26 October 2026).
• It will not type passwords or card details for the user.
• Bookings are made only when the user says so.

Documented controls do not prove that an agent always follows them.

Limits and open questions

• Beta with limited places; access can silently be full.
• Plus plan announced but its price is unpublished.
• The vendor’s team can see conversations to keep the service running (site notice).
• Model providers may change automatically mid-conversation; providers are named on a sub-processors page.
• Booking accuracy and task completion were not tested.

Privacy and security

Privacy policy (read 26 October 2026): model providers are not permitted to train on conversations; providers may retain data briefly for security and abuse monitoring and can change automatically (named on a sub-processors page). The vendor’s team can see conversations to operate the service; administrator access is restricted. Agent memory can be viewed and changed by asking the agent and is deleted on account deletion; Explore-page conversations delete after 30 days of inactivity; payment and tax records are kept seven years.
