Module 1 · The foundations

Why a « cold » budget

Before the numbers, an idea. Understand why Ozorys protects your money the way one protects a treasure: cold, out of reach, under your sole control.

The balance the bank showsRentSubscriptionsBillsRAVAlready committedTruly yours
The bank balance mixes what is already committed with what is truly yours. Ozorys isolates the part actually available.

The illusion of the bank balance

The figure your bank shows is misleading: it ignores your upcoming bills, your rent, your subscriptions. It tells you what you have, never what you can truly spend.

The result: you spend thinking you have room, then the direct debit hits and you're overdrawn. Ozorys replaces this illusion with a single honest number, which you'll discover in the next module.

The « cold storage » principle

In the crypto world, the most precious assets are kept in « cold storage »: disconnected from the Internet, beyond the reach of hackers. Ozorys applies this exact principle to your budget.

Key point

Your financial data lives encrypted on your phone, never in clear text on a server. That's the difference between an exposed « hot budget » and a sheltered « cold budget ».

Zero-Knowledge & Offline-First

  • Zero-Knowledge: Ozorys encrypts everything with your code (AES-256-GCM). No one — not even us — can read your ledger.
  • Offline-First: the app works without Internet. You depend on no server to view your money.
  • No bank: no aggregator, no access to your real accounts. You enter what you want to track, period.

Module quiz

Test your knowledge

Question 1
Why is the balance shown by your bank misleading?
Explanation: The balance shows what you have right now, but not what's about to be debited. Hence the need for disposable income.
Question 2
What does « Zero-Knowledge » mean at Ozorys?
Explanation: Your data is encrypted on your device with your code. The key never leaves your phone.
Question 3
What does « Offline-First » mean?
Explanation: Ozorys is built to work locally first. The network is only useful to sync in Tribe Mode.
Module challenge

Spot your illusion

Open your banking app and note the displayed balance. Then mentally list everything still to be debited this month (rent, subscriptions, bills). The gap between the two is exactly what Ozorys will make visible.
