The Vault

Your keys stay locked
until you're safe.

Drop your keys into the vault before your first drink. The magnetic lock engages automatically. When you're ready to leave, blow into the integrated breathalyzer sensor.

Below the legal limit? The vault opens. Above it? Your keys stay locked, and the app helps you call a ride.

How it works

01

Lock

Drop your keys into the vault before you start drinking. One press locks them in.

02

Blow

When you're ready to leave, blow into the sensor. Results in under 5 seconds.

03

Go

Under the limit? Vault opens. Over? It stays locked and suggests a ride home.

The Why

Because it's personal.

Two of my close friends got DUIs within the same week. Not because they were reckless people — because in the moment, after a few drinks, the decision to drive feels easier than it should.

bacctrack removes that decision entirely. You lock your keys before you drink, when your judgment is still clear. By the time you want to leave, the vault holds you accountable.

This isn't about punishment. It's about prevention.
