FAQ & support

Carbon is the iPhone app for people who love cars. It brings the cars you own and the ones you dream of into one garage: type in the name of a car and Carbon fills in its spec sheet from more than 9,000 models; then you add your photos and memories. For the ones you own, Carbon also keeps track of their due dates and their documents. You’ll also find the history of 395 cars in the Stories tab, Spec Battle duels and 81 distinctions to earn.

Anyone who loves cars, whether they own one or not. Use it for the one car that matters to you, a whole collection or just your dream garage. All you need is an iPhone.

No. Type in the model and Carbon finds its spec sheet among more than 9,000 cars and fills in the specifications. If yours isn’t in the catalogue, you can add it yourself: the marque, model and year are enough.

Yes, for the cars you own. On their spec sheet, the Due Dates section offers insurance, vehicle inspection, service, oil change, timing belt or a custom due date. Carbon works out the next date at the interval you choose, then reminds you at 9am: 30 days ahead by default, on the day, and a week later if it is not done. A due date marked as done is noted in the car’s logbook and, if it comes round again, Carbon works out the next one. The suggested intervals are a guide: adjust them to the rules where you live.

Carbon is designed for iPhone with iOS 26 or later, in portrait mode. The app is available in English and French.

The catalogue is checked all the time, but cars have a century and a half of history behind them. In the app, the “…” menu on a spec sheet offers Suggest a correction, and at the end of each Story a link lets you report a factual error. The message is pre-filled: all you have to do is correct the line that’s wrong. If your car isn’t in the catalogue, add it by hand, then send it to us as a suggestion: the models we accept are added to the catalogue in an update. You can also write directly to contact@carbonapp.eu.

No. Carbon works entirely on your device: your cars, photos, documents, due dates and history stay on your iPhone, and reminders are scheduled on it. There is no Carbon account and no analytics. Purchases and any backups are handled by Apple. Full details are in the privacy policy.

On your iPhone, filed with their car. Registration, insurance certificate, invoices: scan them with the camera or import a photo or a PDF, up to 25 MB per document. Carbon never sends them anywhere, and their thumbnails are blurred in Private Mode. Like the rest of your collection, they are part of your iPhone’s backup (iCloud or computer). A scanned copy does not replace the originals the law asks you to show.

Your data is included in your iPhone’s normal backup (iCloud or computer). Check that iCloud Backup is turned on in Settings → [your name] → iCloud. Premium subscribers can also export their collection’s details as a CSV file. The export doesn’t replace a full backup and includes neither photos nor documents; Carbon can’t import CSV files.

Deleting the app erases all the data it holds on the device. You may be able to get it back by fully restoring an iPhone backup that still contains it; reinstalling the app on its own isn’t enough. Deleting the app doesn’t cancel your subscription: Premium stays linked to your App Store account and comes back with “Restore Purchases”.

No, it’s an option you can turn on in the app’s settings. Authentication is handled entirely by iOS; Carbon never has access to your biometric data.

Two cars in your garage, real or dreamed, the whole catalogue (more than 9,000 spec sheets), three Spec Battle duels a month and the opening of every Story. The free version has no time limit.

Premium unlocks unlimited cars, all 395 Stories in full (rivals and anecdotes included), unlimited Spec Battle duels and the export of your collection as a spreadsheet (CSV). Two plans: €4.99 a month or €29.99 a year (about €2.50 a month). Reference prices in euros, including VAT, billed by Apple; the price shown in the app when you buy is the one that applies. See the Terms.

In Settings → [your name] → Subscriptions → Carbon Premium → Cancel Subscription, at least 24 hours before the renewal date. Premium stays active until the end of the period you’ve paid for, and your data is left untouched.

Payments are processed by Apple, so refunds are requested at reportaproblem.apple.com, signed in with your Apple Account. Apple reviews each request under its own terms and applicable law. Refunds aren’t automatic.

Open the Premium screen in the app’s settings and tap “Restore Purchases” while signed in with the same App Store account. You won’t be charged again.
