Common questions

Do I need an account?
No. The app works straight away: the strategy builder and payoff charts use live Yahoo Finance data with no credentials.

What does the Interactive Brokers import need?
A Flex Web Service token and a query id, both generated in your own IBKR account management. They are stored in the iOS Keychain on your device and sent only to Interactive Brokers.

Where is my data kept?
Only on your device. There is no backend server and no cloud sync; uninstalling the app deletes everything. See the privacy policy.

Is this investment advice?
No. Payoff is an analysis tool. It shows the mathematics of a position; the decisions are yours.
