    FAQ

    Does the app connect to my bank?

    No. You only import files that you select yourself.

    Is my data saved automatically?

    Not by default. You can enable autosave or save the project manually.

    Will the debt schedule match my lender exactly?

    Not necessarily. A contract may use daily interest, variable rates and additional fees.
