FAQ: rate updates and offline mode

The app includes a bundled public interest rate dataset based on statistics from the Bank of Finland and the European Central Bank. When online, the app fetches the latest public rate report directly from the Bank of Finland report server. Offline, the app works normally with the most recently saved data.

FAQ: privacy and deleting data

The app is used without registration or sign-in. All loan details and reminders you enter are stored only on your own phone or tablet. You can edit or delete your loan details at any time in the app or by uninstalling the app.

FAQ: Korkopassi subscription and restoring purchases

The Korkopassi annual subscription is managed through your Apple ID or Google Play account. If you switch devices or reinstall the app, you can restore an active subscription using the Restore Purchases button in the app. The subscription renews automatically each year and can be cancelled at any time at least 24 hours before the end of the current period in your App Store or Google Play account settings.
