Support

Need help with Whatifi, found a bug, or have feedback? We’d love to hear from you.

Common questions

Is my data stored in the cloud?
No — your plans are stored locally on your device. Uninstalling the app removes that data unless you have a device backup that includes app data.
Does Whatifi connect to my bank?
No. You enter balances, income, and assumptions manually for full control and privacy.
Which countries and currencies are supported?
Whatifi supports 14 display currencies (EUR, USD, GBP, CAD, CHF, CZK, PLN, DKK, SEK, NOK, HUF, RON, BGN, and ISK), plus an "any country" mode where you enter your income net of tax. Czech plans go further, with full payroll (employee HPP) and tax modelling built into the engine. The app is fully localized in English and Czech.
How do I reset my plan?
Open the Assumptions tab and choose 'Reset & run onboarding again'.
