Personal & business finance, without giving anyone your bank password
Vaultly is a Windows desktop app that brings your accounts, budgets, transactions, and net worth into one place — without sending any of it to a SaaS company's servers. Your data lives in a SQLite file on your own machine. You decide what gets imported, what gets categorized, and what gets shared with the AI advisor.
Built for two audiences in one product: people who run their household finances and want a Mint replacement that respects their privacy, and small-business owners who keep books separate from personal but don't need a $40/month Xero subscription.
What's in the box
Bank sync, three ways
Connect via SimpleFIN Bridge for read-only daily refreshes from 10,000+ U.S. and Canadian banks (no Plaid screen-scraping, no Mint-style aggregator dependency). Connect via Plaid for instant authentication on the institutions that support it. Or skip aggregators entirely and import OFX/QFX files directly — the same format your bank's "Download to Quicken" button has been producing for two decades.
Categorization that actually learns
Auto-categorization rules, merchant cleaning, and a pattern engine that turns "AMZN MKTPLC US*XV3W2" into "Amazon Shopping" once and forever. Splits, transfers between your own accounts, and recurring detection are built in — no plugins, no monthly per-feature billing.
Budgets & cash flow
Monthly budgets per category with progress bars, "spent so far" projections, and over-budget alerts. The dashboard shows income vs spending across the last six months, top merchants, daily cumulative spend, and where your debts are landing on the payoff curve.
Net worth & assets
Track real estate, vehicles, crypto (live prices via CoinGecko), and any other custom asset alongside your bank accounts. The Net Worth view shows the trend month-over-month and lets you slice by asset category.
AI Advisor & Planner
Optional. Brings your own Claude or OpenAI API key — we don't proxy through our servers, so your transaction history never leaves your machine until you decide to ask a question. Use the Advisor for "should I refinance my mortgage given these numbers" conversations, and the Planner to generate scenarios ("retire at 60 with 5% returns, $X savings rate, $Y target").
Backup, recovery, and your file
Daily automatic backups to a local folder you control. Manual backup-on-close option for power users. The whole thing is one .db file you can copy to another machine, restore from, or audit yourself with any SQLite browser.
Why desktop, not web
Cloud finance apps work great until they don't. Mint shut down in 2024. Aggregators get sold and "rebrand". A SaaS app that holds your bank credentials is a single point of failure for your entire financial life.
Vaultly is yours: installed on your machine, data on your disk, no subscription. The only thing that talks to a server is the license validation (once a launch, eight-second timeout, falls back to your local cache when offline). Bank sync is read-only and direct.
Pricing
One-time purchase, $49. Includes one year of free updates. After the year, the app keeps working forever — you only pay again if you want the latest features. Try it free for 30 days, no credit card.
