Vault App is a zero-knowledge password manager with end-to-end encryption. Features include multi-factor authentication, trusted devices, an activity log, password generation, and export/import, plus a free plan and a paid plan with Stripe.

I designed the brand and product experience, and built the full stack: the interface, device-side encryption, multi-factor auth, trusted device flows, activity logging, export/import, Stripe billing, and the infrastructure that syncs and stores encrypted vault data.
