FAQ
Common questions.
What is Stays?
Stays is a Stang Pro feature in the iPhone app that counts how many days you have spent in each country, worked out from where your expenses happen — no GPS tracking and no manual check-ins. It is built for visa limits and tax-residency thresholds: you see a running day count per country, so a 90-day visa or the 183-day tax rule never catches you by surprise.
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. You set one home currency and up to four secondary currencies, and every amount is converted automatically using live exchange rates.
Does Stang work on iPhone and Android?
Stang is a native app on the App Store for iPhone, and it also works as a Progressive Web App in any browser. On Android, open stang.app in Chrome and choose Install app; on iPhone you can also use Safari, Share, Add to Home Screen.
How do I log expenses?
You type it the way you would say it — "lunch 85 THB" or "coffee 4.50 SGD yesterday" — and Stang works out the name, amount, currency, category, and date, then converts it to your home currency. There is no form and no dropdown. You can also log by messaging the Telegram bot, or by photographing a receipt.
How is Stang different from other budget apps?
Stang is built for people who spend across several currencies at once. Most budget apps make you pick a currency from a menu and convert by hand; Stang detects the currency from what you typed and converts everything into one home currency automatically. Logging takes one message rather than a form. And it is the only budget app that turns your ordinary spending into a day count per country for visa and tax planning.
Is my financial data secure?
Your data is stored with row-level security, so only your account can read your transactions. You sign in with Google or an emailed one-time code, and no passwords are stored. Stang does not sell or share your data, and third-party analytics run only on the public marketing pages, never inside the app itself.
