Frequently asked questions
Do I need an account?
No. Curva Direta has no accounts, no sign-up and no cloud: everything runs and stays on your device.
Where do the rates come from?
Simulations use the parameters you enter and publicly available reference rates for Brazilian treasury bonds (Tesouro Direto). Always confirm current rates at the official Tesouro Direto website before investing — the app’s figures are estimates.
Is this investment advice?
No. Curva Direta is an educational simulator. It does not recommend buying or selling any bond, and actual returns depend on market conditions, taxes and fees. For decisions that matter, consult a qualified professional.
How do I delete my data?
Curva Direta has no account and stores everything on your device. Deleting the app from your phone erases all of its data.
Why does the app show ads?
Ads are what keep Curva Direta free. Ads are served by Google (AdMob); the app never shares your content or personal details with it, and on iOS you control cross-app tracking through the App Tracking Transparency prompt.
Finding your app version
When reporting a problem, include the app version: open Curva Direta and go to Settings — the version number is shown at the bottom of the screen. It helps us reproduce exactly what you are seeing.
