How does Refer a friend work?

Settings → "Refer a friend" shows your personal link ("Copy"). When someone signs up through it and subscribes to Pro, they get their first month free and you get a month of Pro credited to your next bill. Credits apply automatically on your next Stripe invoice, up to 12 banked months at a time. Free-plan sign-ups don't earn credit. This is separate from the Affiliate Partner program, which pays cash commission.
