A local-first expense tracker that never sends your financial data to the cloud.
Bank-grade encryption. Zero tracking. Complete ownership.
Launching March 2026 • Mac, Windows, Linux
Not just a promise. It's in the architecture.
Your transactions live in an encrypted database on your device. Not in someone else's cloud. Not on our servers. Yours.
One password to unlock your vault. We never see it, never store it. 256,000 PBKDF2 iterations make brute-force attacks impractical.
Track expenses on a plane, in a cabin, or anywhere without cell service. No internet required. No "sync failed" errors.
Add a transaction in 3 seconds. See your balance at a glance. No cruft, no upsells, no "premium features."
Set category budgets. Track spending trends. Export to CSV. All the tools you need, none of the complexity.
No subscriptions. No hidden costs. No "freemium" tricks. Download once, use forever. Support via optional donations.
Mint, YNAB, Copilot — they know your income, spending habits, bank accounts. That data is valuable. Some get breached. Some get acquired. All of them mine your habits.
$15/month for a budgeting app. Really? That's $180/year to track your own money. After 5 years, you've paid $900 for software that should cost $0.
When the company shuts down (or gets acquired), your data disappears. Export to CSV? Sure, but good luck importing it anywhere else.
Vault launches in March 2026. Join the waitlist to get notified when the first version is ready — plus occasional updates on development progress.
No spam. No selling your email. Unsubscribe anytime.
