FAQ
Common Questions
What is DolarMap?
DolarMap monitors USD/BRL quotes in real time across multiple cryptocurrency exchanges and brokers, showing the best opportunities to buy, sell, or arbitrage dollars compared to the official PTAX rate from the Central Bank of Brazil.
Is the information financial advice?
No. All data displayed is strictly informational. DolarMap does not recommend any transaction or guarantee any financial outcome. Always consult the broker's own terms and a qualified financial professional.
Do I need to create an account?
No. The app works fully with an anonymous device identifier (UUID). Optionally, you can Sign in with Google to back up your alerts across devices - this is entirely voluntary.
Why did I stop receiving alert notifications?
Notifications may stop if the alert was set to trigger once, push permissions were revoked in system settings, the alert was paused manually, or the data source was temporarily unavailable.
