Remember that if you delete your Reddit app on your phone, your vault will be deleted as well.

… and you would need your seed phrase or Reddit vault password to recover it.

Your vault is an Ethereum wallet that is incorporated into the official Reddit mobile app for iOS and Android. This is where your Moons are stored.

Even though you have an iPad with the app, your moons are still stored on your mobile app.

You are provided with a seed phrase and Reddit vault password to restore your vault in case you delete the app or lose or break your iPhone/Android phone.

So it’s very important that you write down your seed phrase externally, this is the only way your wallet is completely backed up.

And one last tip: if you have an iPhone, you cannot access your seed phrase without having Touch ID enabled on your phone.
