The DAU Vault operates as a decentralized application. It does not collect or store any information capable of identifying a user or their phone. However, within the app's "Settings," there is a "Personal Information" section intended for users who choose to voluntarily submit their phone number or email address for marketing purposes. Even if phone numbers and/or email addresses are provided, they cannot be linked to your digital wallets within the app. For more details, we encourage you to consult our Privacy Policy.
