Common questions
How do I restore my Pro purchase?
Open Settings in Cordon and tap Restore Purchases, signed in with the Apple Account you bought it with. Pro is shared with your Family Sharing group.
How do I get a refund?
Purchases are handled by Apple. Request a refund at reportaproblem.apple.com.
My server won’t connect. What now?
Cordon shows the reason, such as wrong password, closed port or certificate mismatch, with Try again and Dismiss. Check the details with your server provider, then try again. If it still fails, email us the diagnostics.
Cordon refused my link. Why?
Cordon refuses links it can’t run and says why, so you never end up with a dead server in your list.
