Retirement Planner With 154 Years of Market Data Launches on Android, Collects No Data
Thessaloniki, Greece – Aug 17, 2026 – FIRE – Financial Planner runs Monte Carlo simulation, historical backtesting and stress tests entirely on the phone: no account, no ads, full offline use
A retirement planner that replays plans through every market crash since 1871 is now on Google Play. The app, FIRE – Financial Planner from firenum.com, runs every calculation on the device itself. There is no account to create and no financial data leaves the phone.
Users build a month-by-month plan from their real finances: salaries, pensions, retirement accounts, rental income, debts and one-time events such as an inheritance. Each account grows at its own rate. Each expense carries its own inflation. The plan can span 50 years.
Three tests answer the question every retirement saver asks: will the money last? Historical backtesting replays the plan through every market period since 1871, including 2008, the dot-com crash and the Great Depression, using the Shiller S&P 500 dataset. Monte Carlo simulation runs up to 5,000 randomized market scenarios and reports the probability the portfolio survives. Six stress tests model the fears that keep planners up at night: a 40% market crash, a lost job, doubled expenses, an inflation spike.
The privacy design runs against the norm for finance apps, where signup screens and data collection are standard. This app stores everything on the device, works in airplane mode and exports to CSV at any time. The app is free, with no ads and no paid tier.
“Retirement plans contain the most sensitive numbers a person has. The way to protect that data is to never receive it. The phone is powerful enough to run 5,000 simulations on its own, so nothing needs to leave it,” said the team behind firenum.com.
FIRE – Financial Planner is available on Google Play at play.google.com/store/apps/details?id=com.firenum.twa. It supports eight currencies with automatic detection: USD, EUR, GBP, JPY, CAD, AUD, CHF and INR. The same planner runs in any browser at firenum.com.
