ARCHITECTURE

Professional Financial Infrastructure

Built around consistent records, traceable corrections, and double-entry bookkeeping principles.

Double-Entry Bookkeeping

Every transaction is written in two places: where the money comes out and where it goes.

Example

100 TL market expense → 100 TL is removed from Cash account, 100 TL is added to Groceries category. Thus, where your money goes is always traceable.

Immutable Records

No recorded transaction is deleted or changed.

Why?

Made a mistake entering expenses while waiting at the register? The system creates an "adjustment entry". The original record is kept as a document. Your financial history cannot be manipulated, it always remains correct.

History Preserved

The dollar rate is 35 TL today but you bought at 32? That record is kept with 32 forever.

Why?

Your past records do not change because the exchange rate changed. The reality of that day is preserved. "Historical Cost" principle. Your financial history is sealed.

All or Nothing

A transaction written to the database either takes place completely or is not written at all.

Why?

Transfer steps are applied within a database transaction; if one step cannot complete, the related changes are rolled back.

Exchange Difference Tracking

When you exchange dollars, your gain or loss is tracked in the same account.

Example

When you bought $100, the rate was 32, you sold at 35. The 300 TL difference is recorded as "Exchange Gain". Know how much profit/loss you made from foreign exchange transactions.

AES-256 Data Encryption

Your data is encrypted with AES-256. Only you know the PIN.

Why?

Financial content is encrypted on the device before optional synchronization and is transferred to the service infrastructure in encrypted form.
