Stop opening three banking apps to answer one question. Syandix Cash shows your real cash position across all accounts — your burn rate, your runway, what you can afford today. No passwords. No bank logins. Completely private.
Most middle-market investors with two or three bank accounts, a credit card and some savings have no single honest picture of their actual cash position. Syandix Cash fixes that.
Every feature exists to answer that question faster, more accurately and more privately than anything else available.

Syandix Cash grows in four clear phases. Each phase ships once the one before it has earned its place.
Manual daily expense entry. Monthly overview and category breakdown. CSV export. Multi-currency support. The foundation of Syandix Cash.
12-month history, spending charts, category comparisons and the full multi-currency trip rollup.
Daily burn rate, cash runway, liquidity timeline, recurring transactions, budget alerts and trip affordability modelling.
CSV bank import with learnable mapping rules, duplicate detection, credit card balance tracking, transfer reconciliation and FX spread analysis.
Syandix Cash is built on a privacy-first architecture by design — not as a compliance checkbox. Here is exactly what we do and don’t touch.
Syandix Cash never asks for your banking username, password or PIN. Data enters via manual entry or CSV import only. No OAuth, no PSD2 AISP connection — by design, not by roadmap.
All transaction data is stored on your iPhone via iOS SwiftData. We have no server, no database and no copy of your financial data. Uninstall the app and every byte is permanently deleted.
When you import a bank CSV, the file is processed entirely on-device. Column mapping, merchant rules and duplicate detection all run locally. No file is transmitted to any server.
Firebase Analytics tracks aggregated, anonymised events (installs, retention, paywall exposure) via Apple’s privacy-safe framework. No individual transaction data, amounts or identities are collected.
