Event properties
Properties make an event useful for filtering, segmentation, and breakdowns. Examples include plan, price, device, campaign, app version, or content type. Teams should use stable names, consistent data types, controlled values where possible, and clear definitions. Sensitive or high-cardinality values should be reviewed carefully because they can create privacy, cost, and usability problems.
