## Data and privacy
This card uses its configured properties and live card data.
Courses, rooms and times only; never students or seating lists.
## Properties
For theme, background, accent and position, see [Common properties](/docs/cards/#common-properties).
Set static properties in `params`. Bind `data` to a project card data key for live values; that document holds only dynamic properties. Without a data key, put the complete configuration in `params`. Nested rows describe the contents of their parent property.
