Frequently asked questions

Where is my data stored?

On your device. With Premium, also in your own private iCloud. We have no access to it and we run no servers.

Does the app work without Premium?

Yes, fully. Without Premium everything is stored locally and you can export a backup at any time.

Where are my questions to the AI assistant sent?

Nowhere. The assistant runs on Apple's models directly on your device.

How do I attach a contract to a payment?

Open the payment's detail, go to Documents and tap +. You can scan the document, take a photo, or pick a file.

Where do I enter my car insurance?

Vehicles → the car → Payments → +. The payment counts towards the car's monthly costs and towards its cost per kilometre.

How do I hide amounts when I show someone my phone?

Tap the eye next to the total, or turn the phone face down and back. In the app switcher amounts hide by themselves.

How do I restore a purchase on a new device?

In the app: Settings → Restore purchases.

How do I cancel the subscription?

iOS Settings → Apple ID → Subscriptions.

What happens to my data if I delete the app?

Local data is erased together with the app. With Premium a copy stays in your iCloud until you delete it there.
