There are no PDFs to email around and nothing to print, but every deal is a real agreement, and you sign it right in the app.
When you apply to a deal or accept an invite, the final step shows you the Creator Platform Agreement plus that deal's exact terms: pay, deliverables, and usage rights. You sign with your finger, and that signature seals the agreement.
The signed record: the terms exactly as they were shown to you, with the time you signed: is stored permanently, so there's never ambiguity about what was agreed. You can review any deal's terms in the app whenever you want.
