- An event is each web analytics event (pageview, click, …) or each entry inserted via the API.
- A replay is one recorded session in one browser tab.
- Trial and Starter limits are hard: when you reach one, collection pauses until next month or until you upgrade. You never get a surprise bill. Data you already collected is untouched.
- Data is kept until you delete it (erasures, or deleting a stream).
