Ahhh, the Vault. We promise it's not as scary as it sounds. Have you ever used a safety deposit box? Me neither!
Jokes aside, It is essentially where your valuable data lives within the app. Within your Vault, you can enter as much (or as little!) personal and identifiable information that will count toward your overall data score.
It is the center and the final word of your relationship with your data. You own your vault; we simply access it - if and when you consent.
