How does backup work on iPhone?

Heartside is part of your iPhone’s own backup: iCloud Backup, or a backup to your computer. There’s no sign-in in our app, and nothing goes to our servers. To turn on iCloud Backup, open the Settings app, tap your name, then iCloud › iCloud Backup. When you set up a new iPhone from that backup, your pets and readings come with it, breathing videos included.

After a restore, live sharing may start fresh: every pet and reading is there, and you can share a pet again with a new link. For a copy you control, use Settings › Save a backup file.
