Yes! Tap the keyboard icon in the scanner view to manually enter a barcode number. This is useful if the barcode is damaged or hard to scan.

ProductWho works best with grocery items, beverages, personal care products, and household goods. Products from major brands are more likely to have complete ownership information. Electronics and furniture may have limited data.

We aggregate data from multiple open databases including Open Food Facts, Open Products Facts, and other public sources. Brand ownership information is curated from public company records and verified sources.

We strive for accuracy and regularly update our database. However, corporate ownership can change through mergers and acquisitions. If you notice an error, please contact us at support@productwho.com.

Our database currently tracks over 3,500 brands owned by more than 400 parent companies worldwide. We continuously add new brands and companies.

When a product's brand isn't explicitly listed in the database, we attempt to detect it from the product name. This is usually accurate, but you may want to verify independently for important decisions.

Knowing the parent company helps you make informed purchasing decisions. You might want to support smaller companies, avoid certain conglomerates, or simply satisfy your curiosity about the corporate world.

No. Your scan history is stored only on your device and is never sent to our servers. We respect your privacy and don't track your shopping habits.

We collect minimal anonymous analytics to improve the app (like crash reports). We do not collect personal information or track individual product scans. See our Privacy Policy for details.

Yes, you can clear your entire scan history at any time from within the app. Go to the history screen and tap "Clear History".

Camera access is required to scan barcodes. We only use the camera when you're actively scanning and never record or store images.

You need an internet connection to look up products. However, previously scanned products are cached on your device and can be viewed offline from your scan history.

Make sure you have good lighting and hold your phone steady. Try using the flashlight toggle if it's dark. If the barcode is damaged, use the manual entry feature instead.
