What happens when someone replies to my boat?

You get a notification. Open it, or open Paper Boat, and tap Open Reply. Then you can:

• Send a Heart Back to say thank you.
• Keep This Kindness to save the reply in Storage.
• Release to Ocean to let it go. This deletes the reply and your story for both of you.

Take back a boat: open My Boats and tap Take back. This deletes your story and any reply. It still counts toward today's boats.

Boats that nobody answers are deleted after 7 days. After 3 people pass on a boat, its story is deleted.
