Paddle status
Paddle checkout is not active for Sina. Its medical decision-support features and usage-credit sales require written AUP clearance before any Paddle integration. This notice does not itself make the product eligible; any currently offered checkout identifies its actual payment provider.
Frequently asked
What is a token and how is it used?
Usage is calculated from the input, attached files and response length; the cost appears beside each answer.
Can I cancel anytime?
Yes, anytime. You keep access until the end of the paid period, and top-up tokens remain.
How is the Clinic/Team plan different?
Multiple seats with shared tokens, a team management panel, role-based access and audit logs for labs and clinics.
