FAQ

Common questions.

Is Stang free to use?

Stang is free to start — every new account includes a 14-day premium trial, no credit card required. After the trial, the free tier gives you unlimited expense logging, multi-currency support, and monthly overviews. Premium ($4.99/month or $39/year) unlocks AI-powered insights, receipt scanning, CSV import, and Telegram logging.

What currencies does Stang support?

Stang supports all major currencies including SGD, USD, EUR, GBP, THB, MYR, JPY, AUD, HKD, IDR, INR, PHP, VND, CNY, and KRW. Set a home currency and up to four secondary currencies — all amounts are automatically converted for totals and budgets using live exchange rates.

Does Stang work on iPhone and Android?

Yes. Stang is a Progressive Web App (PWA) that works on any device through your browser — no app store needed. Install it to your home screen on iPhone (Safari → Share → Add to Home Screen) or Android (Chrome → Install app) for a full app-like experience with offline support.

How do I log expenses?

Just type naturally — "lunch 85 THB" or "coffee 4.50 SGD yesterday" — and Stang's AI automatically categorises it, detects the currency, and adds it to your log. You can also log via Telegram by messaging @StangAppBot, or use the Telegram bot to attach receipts to past transactions.

How is Stang different from other budget apps?

Stang is built for people who spend across multiple currencies. Unlike most apps that require manual currency selection, Stang detects currencies from natural language and converts everything to your home currency automatically. It's designed to be fast — logging an expense takes one message, not a form.

Is my financial data secure?

Yes. Your data is stored with row-level security — only you can access your transactions. Sign in via Google or email OTP, no passwords stored. We don't sell or share your data, and third-party analytics only run on the public landing page, never inside the app.
