How do I back up my data?
Edited
The best way to back up your data is to create an account. With an account, your favorites, collections, and your own content are saved so you can restore them if you reinstall the app or switch devices.
To create an account, follow these steps:
Go to the main screen
Tap the 👤 profile icon
Tap the ⚙️ Gear icon or "Settings" in the upper right corner
Tap "Sign in"
Choose "Sign in with Apple" or "Sign in with Google"
On iOS, you can also back up your app data through iCloud. Make sure iCloud backup is turned on in your phone's Settings.
