VAULT
Total Control Over Your Money.
Most finance apps sell your data to banks and advertisers. Vault changes the game. It analyzes your spending with AI that lives entirely on your phone, so no cloud is required to use it. Track everything by hand and it never leaves your device, or link a bank through Plaid when you want automatic updates, where your login happens on Plaid's secure screen and your password never touches Vault. Secure, fast, and yours.
The Mission
Privacy by design.
Built for the future.
In an age of surveillance capitalism, your most intimate data (your finances, your thoughts, your conversations) is mined, packaged, and sold by the very tools you trust to manage it.
VAULT was engineered to reverse this dynamic. By running advanced AI models locally on your device's NPU, we provide the intelligence of the cloud with the privacy of a vault.
No servers. No accounts. No subscriptions. Just a powerful application that belongs to you.
Workflow
