Zero Permission LLC builds tools that earn their keep by doing one job well — and by not extracting from you on the side.
A zero-permission financial runway calculator for Android.
See exactly when your money runs out. Enter your income and expenses, watch your balance project forward day by day, stress-test your future with Monte Carlo simulation, and optimize debt payoff, bill timing, and savings goals. No cloud, no accounts, no tracking — ever.
Honest calculators for FX carry trades — runway, not just expected return.
Stop guessing how long your carry trade survives. Stress-test multi-rung carry positions with Monte Carlo, compare pairs by ATR-ranked volatility, and run quick swap math. Free and ad-supported, hosted on the open web at carryhorizon.com.
Zero Permission's promise is specific by surface, not vague at the umbrella. Software you install from us is governed by one set of rules; software you visit on the open web is governed by another. Both are designed to keep your data out of our hands.
You have zero permissions. Nothing leaves your device except payment processing. No accounts, no cloud sync, no tracking, no analytics, no ads — ever. AvoidZero is the canonical example.
We use cookieless server-side traffic counts only — no tracking pixels, no third-party analytics, no fingerprinting. Some of our sites host ads to keep them free, in which case third-party ad networks operate under their own published privacy policies, which we disclose. Carry Horizon is the example here.
