Can I export everything, and in what formats?

Yes, at any time, without asking permission: leads with numbers, full transcripts, appointments, filtered-call history, opt-out registry. CSV covers everything — the standard that opens in Excel, Numbers or Google Sheets — and structured JSON is available for technical hookups. The export filters by period, line and status, and includes exact timestamps. It's a property right, not a premium option: your data leaves when you do, in full, from first day to last.
