Most fintech apps want your email, your bank login, and your transaction history. FinTech Lite wants none of that.
I built this because I wanted to check my subscription "burn rate" and model debt payoff scenarios without handing over my data to a VC-backed startup.
What's Included:
Subscription Auditor: Manually list your recurring costs to visualize your "Monthly Burn" and find leaks in your budget.
Debt Destroyer: A visual playground to compare the Snowball vs. Avalanche payoff methods side-by-side.
Freelancer Tracker: A simple ledger for gig workers to log irregular income and estimate tax set-asides instantly.
The Privacy Stack:
No Database: It runs entirely in your browser using the Local Storage API.
No Accounts: You can't sign up even if you wanted to.
Data Portability: Export your data to JSON (for backup) or CSV (for Excel) anytime.
