To remove someone from your cardmate list, you'll hide them first and then delete them permanently.
Step 1 — Hide the cardmate
iOS: Swipe left on their name, then tap to Hide.
Android: Hold down on their name, then tap Hide.
Step 2 — Delete the hidden cardmate
Expand the hidden cardmates section to find them, then:
iOS: Swipe left on the cardmate and tap to Delete.
Android: Hold down on the cardmate and tap Delete.
Note: You can only permanently delete cardmates who show "0 rounds" next to their name. If they have rounds recorded, you'll need to remove yourself from those scorecards first. See How do I edit or delete a finished round?
