About MyMoney
A unified financial operating system built with passion for solving real-world personal finance problems.
🎯 Our Mission
To provide a unified, privacy-first financial operating system where every individual has complete clarity over their financial life without ever compromising their personal data.
👁️ Our Vision
A world where personal finance tools empower users through mathematical transparency rather than exploiting them through advertising, data brokerage, or predatory credit card recommendations.
💡 Our Philosophy
Your money, your rules, your hardware. Financial software should function like a precision Swiss watch — completely offline, fully predictable, and strictly owned by the person using it.
Our Core Principles
The engineering philosophies behind every decision in the application.
Unified Truth
Every transaction, split debt, budget deduction, and recurring expense lives in a single, coherent SQLite ledger. No app switching, no duplicate entries, one source of truth.
Mathematical Integrity
We never approximate numbers. In v3.0.0, our deterministic backward balance engine computes exact historical start and end balances across every transaction.
Privacy as Architecture
Privacy isn't a toggle or a marketing afterthought — it is the fundamental core architecture. Zero network calls for financial data, zero third-party telemetry SDKs.

Why MyMoney Was Created
In 2026, managing your money has become an exhausting chore. Your bank app records raw deposits and withdrawals, but gives zero insight into categorical budgeting. Your expense tracker lets you tag expenses, but knows nothing about your bank balance. When dining out with friends, you log amounts in Splitwise, which completely isolates the debt from your actual bank accounts.
The Indian and global financial ecosystem is deeply fragmented: users balance physical cash, multiple bank accounts, UPI apps, credit cards, digital wallets, and peer-to-peer debts to friends and roommates. Reconciling these requires hours of mental math or fragile spreadsheets that quickly fall out of date.
MyMoney was created to prove that personal finance does not have to compromise your privacy or sanity. A single application, a unified ledger, mathematically perfect reconciliation, and 100% on-device data sovereignty.
