Quick support
- No external data source: Carnio talks to no server of the developer. Only the Google Mobile Ads and Google User Messaging Platform kits, for advertising and consent, iCloud (CloudKit), for sync, and the App Store, for the subscription, use the Internet. The developer adds no analytics tool.

FAQ
Is my data sent to the developer?
No. The developer has no server and sees nothing. Your data stays on the device and in your private iCloud database, which syncs it between your devices; invoice photos and PDFs stay on the device only.
How do I import a logbook from CarbuFrance or CarbuEspaña?
Export the logbook from the other app (a .carnio file), then open it in Carnio: the import asks for confirmation and adds no duplicates. From a station page in those two apps, the button to add a fill-up opens Carnio with the station already filled in.
How is consumption calculated?
From full tank to full tank: partial fill-ups are added up, and a fill-up without an odometer reading breaks the chain. For electric vehicles it comes from the charge percentages and the AC or DC efficiency the app learns; for plug-in hybrids, electric kilometers are deducted.
When am I reminded about maintenance?
Each maintenance has a due date, a mileage or both, and a reminder by local notification. Allow them in iPhone Settings › Notifications › Carnio.
How do I export my data?
In the app, a vehicle’s CSV export and PDF report are shared through the iOS share sheet. Nothing is created until you ask for it.
How do I manage or restore the “Ad-Free” subscription?
The app Settings open the subscription (0.99 € per month or 4.99 € per year), with the restore purchases button to get it back on another device. iPhone Settings › your name › Subscriptions lets you cancel it.
Why are there ads?
Carnio is free, with every feature included: a discreet banner funds it, and an optional video gives 6 hours ad-free. The “Ad-Free” subscription removes every ad. Where consent applies, it can be changed in the app Settings.

Data deletion
Carnio creates no account. Deleting the app erases your data and invoices from the device. Data stored in your iCloud is managed in iPhone Settings › your name › iCloud › Manage Storage: the developer has no access to it.
