Free to start. Cheap to keep.

Yes. The free plan gives you unlimited expense logging, full multi-currency support with live conversion, budgets and category limits, monthly overviews, and CSV export — with 30 AI-parsed expenses a month. Every new account also starts with a 14-day Stang Pro trial, no credit card required. When the trial ends you drop to the free plan automatically; nothing is charged and nothing is deleted.

Stang Pro is $3.99 a month, $19.99 a year, or $49.99 once for lifetime access. The annual plan works out to about $1.67 a month. Those are the web checkout prices in USD; if you subscribe inside the iPhone app, the App Store shows the equivalent price in your local currency, which varies by region.

Pro unlocks unlimited AI logging and receipt scanning, Ask Stang follow-up questions about your spending, Stays day-counting per country for visas and tax residency (iPhone), the Weekly Brief recap every Sunday (iPhone), bank CSV import, and Telegram logging on the web.

Yes. Stang Pro is tied to your account, not to a device or a store. Buy it in the iPhone app and it unlocks the web app as well, and the other way round. You only ever need to pay once per account.

Yes. Monthly and annual plans can be cancelled whenever you like and you keep Pro until the end of the period you have already paid for. Subscriptions bought on the web are cancelled from Settings; subscriptions bought on iPhone are cancelled in Settings, Apple ID, Subscriptions. The lifetime plan is a single payment with nothing to cancel.

Nothing is deleted. You keep every expense you have logged and you can still log, budget, and export as much as you like on the free plan. Only the Pro features stop — AI logging returns to 30 a month, and Stays, the Weekly Brief, Ask Stang, and bank CSV import are locked until you upgrade again.
