How do I scan an ingredient label?

Scanning is simple:

• Open NoJunk and tap the "Scan Product" button
• Point your camera at the ingredient list on the product packaging
• Hold your device steady and ensure the text is clearly visible
• The app will automatically detect and analyze the ingredients
• View your instant health score and ingredient breakdown

What do the color codes mean?

NoJunk uses a simple color-coding system to help you quickly understand ingredient safety:

How is the health score calculated?

The health score is based on the number and severity of concerning ingredients found in the product. Products with more harmful additives, preservatives, and artificial ingredients receive lower scores, while products with natural, recognizable ingredients score higher.

Why isn't my scan working?

If you're having trouble scanning, try these solutions:

• Lighting: Ensure you're in a well-lit area. Natural light works best.
• Focus: Hold your device steady and make sure the text is in focus.
• Distance: Position your camera 6–12 inches from the label.
• Angle: Hold your device parallel to the label to avoid glare.
• Text clarity: Make sure the ingredient list is clearly printed and not damaged.

The app doesn't recognize some ingredients. Why?

Our ingredient database covers the most common food additives, preservatives, and chemicals. If an ingredient isn't recognized, it may be:

• A natural ingredient (like "flour" or "water")
• A regional ingredient not yet in our database
• Misread by the OCR scanner due to poor image quality

We're continuously updating our database. If you encounter unrecognized ingredients frequently, please let us know.

Can I scan products in different languages?

Currently, NoJunk works best with ingredient labels in English. Support for additional languages is planned for future updates.

Is my data private?

Yes. NoJunk is designed with privacy at its core. Your scan history stays on your device. Ingredient images are sent to our backend for AI analysis and then immediately discarded — they are never stored. Read the full privacy policy for details.

Can I delete my scan history?

Yes. You have full control over your scan history. You can:

• Delete individual scans by swiping left on any item in your history
• Clear all history from the Settings menu
• Delete the app entirely to remove all data

Does NoJunk require an internet connection?

Yes, for scanning. Ingredient analysis uses a cloud AI service, so you need internet connectivity to scan new products. Your scan history is stored locally and available offline.

How do I compare products?

After scanning multiple products, go to your History tab. Tap "Compare" and select two products to view them side-by-side with their health scores and ingredient breakdowns.

Can I save my favorite products?

Your scan history automatically saves all products you've scanned. You can easily refer back to previous scans to make informed purchasing decisions.

Is there a subscription fee?

NoJunk has a free tier and an optional Premium subscription. The free tier gives you scanning and ingredient breakdowns. Premium unlocks unlimited scans, detailed AI verdicts, and more. See the terms for pricing.
