Why we built ZeroDue

Debt is a question with a date for an answer.

Most tools never tell you the date. They show charts, categories, and streaks — and leave the actual finish line as a vibe. We built ZeroDue to do the opposite: put a real month and year on the calendar, and make every payment feel like it's pulling that date closer.

What we believe.

Four convictions that shape every decision.

  • Debt freedom is a date, not a feeling.

    “Doing better” isn't a destination. A specific month and year is. Every screen in ZeroDue orbits that date — what it is today, and what would move it sooner. If a feature can't justify itself against that question, it doesn't ship.

  • Single-currency simplicity, intentional.

    Each workspace locks to one home currency at sign-up. No FX gymnastics, no surprise conversions on a payoff chart. We support 35 currencies — but only one per account, on purpose. Clarity beats flexibility when the question is “when am I out?”

  • No ad trackers. Your finances aren’t a marketing signal.

    We don't sell, share, or train models on your data. There are no third-party ad pixels on this site or in the app. Your data lives in an isolated workspace, encrypted at rest, behind JWT auth, 2FA, and brute-force throttling. We'd rather earn $9.99/month than rent you out for pennies.

  • Boring math, dressed as a game.

    Under the hood, ZeroDue is a deterministic amortization simulator — the same math an accountant would do, run hundreds of times. On top of it sits streaks, milestones, and a debt-free date that visibly moves. The math is honest. The interface just refuses to be depressing about it.

How we build.

Three product principles, applied without exception.

Principle 01

Honest > flowery

Plain language, no hype.

If a feature isn't here yet, we say so. If a number is an estimate, we label it. Marketing tone shouldn't out-promise the product — it shouldn't have to.

Principle 02

Boring math, reliable

Deterministic, auditable, simulator-driven.

Avalanche, snowball, custom — the math is identical to what you'd do on paper, just run a thousand times in milliseconds. No black-box AI deciding your payoff plan behind your back.

Principle 03

A game layer that respects you

Streaks and badges that earn their place.

Every gamification element ties back to a real financial action. No fake currencies, no engagement traps, no streaks that punish you for taking a sick day. Win the math, get the win.

What we don't do.

Just as load-bearing as the feature list.

  • We don’t sell your data.

    Not to advertisers, not to data brokers, not to “research partners.” Subscription revenue is the entire business model.

  • We don’t show ads.

    No banners, no sponsored debts, no affiliate nudges to refinance with someone we get a kickback from.

  • We don’t lock features behind tiers.

    One subscription, every feature included. No “Pro” badge dangling over the strategy that would actually save you the most.

  • We don’t claim AI does the math.

    The payoff engine is a deterministic simulator — the same arithmetic, every time, auditable. If we ever ship an AI feature, it’ll be labelled, optional, and never the thing computing your finish line.

  • We don’t shame you.

    No red “you spent too much” banners, no guilt-trip empty states. Debt is hard enough without your software piling on.
