What Prova does

Prova is a food product scanner. You point your phone's camera at the barcode on a packaged food product, and Prova shows you what is in it — so you can decide whether you want to eat it.

• Scan a barcode to get the product's nutrition information and ingredient list
• See an at-a-glance verdict on the product, with the reasoning behind it
• See ingredients and additives explained in plain language
• Set a dietary profile (for example gluten-free, vegan, low sugar, or your own allergens) and have products checked against it
• Look back over the products you have already scanned in your history

You do not need an account and you never have to give us your name or email address to use the app. Your scan history and dietary profile are stored on your device, not on our servers. Full detail is in the Privacy Policy.

Reporting a wrong or missing product

Prova does not maintain its own catalogue of products. It looks each barcode up in public and third-party food databases, starting with Open Food Facts ↗. That means coverage varies by country and brand, and the details shown come from whichever source held the record.

If a product is not found

When a barcode returns nothing, Prova shows a "Product not in database" screen with an Identify with photos button. Tap it and photograph the packaging — the front of the pack and the ingredients panel — and Prova will read the label directly to produce a result for you.

If a product is found but the information is wrong

Email us and we will look into it. There is no in-app report button yet. So that we can trace the record, please include:

Other common questions

The camera will not scan

Prova needs camera permission to read barcodes. If you declined it the first time, grant it in your device settings under the Prova entry, then reopen the app. Barcodes also scan more reliably in good light, with the whole barcode inside the frame and the packaging flattened out.

How do I delete my data?

Your scan history and dietary profile live on your device. You can clear your history and reset your profile from within the app, and uninstalling Prova removes everything stored locally.

Is Prova medical or nutritional advice?

No. Prova is an information tool that reports and explains what food databases and product labels say. It is not medical, dietary, or nutritional advice. If you have an allergy or a medical condition, always check the physical packaging and speak to a qualified professional — never rely on the app alone.
