VeganLens Support

VeganLens scans product barcodes and queries public databases to show ingredients, additives, allergens, nutrition information, and an indicative assessment of whether a product is suitable for a vegan diet.

How to get help

For questions, comments, or help with the app, email r.alvarezmar@gmail.com.

You can also report problems or suggest improvements through the GitHub issue tracker. Do not include unnecessary personal information in an issue.

Frequently asked questions

How do I scan a product?

Allow camera access and point the camera at an EAN or UPC barcode. You can also enter the barcode manually. The app queries the available databases and displays the information it finds.

What does “Not enough data” mean?

It means that none of the databases queried provides enough vegan information to show a result. It does not mean that the product is vegan or non-vegan. Always check the official product label.

What is the indicative ingredient-based verdict?

When Open Food Facts does not provide a vegan analysis, VeganLens can inspect the ingredient list locally. This result is indicative: not detecting animal-derived ingredients does not confirm that a product is vegan. Check the label and any traces or certifications.

How can I contribute data to Open Food Facts?

From the contribution screen, you can fill in product data, recognize ingredients with OCR, and add photos, then explicitly start the submission. You do not need to sign in to the app. Contributions are sent to the database you select; do not include personal information in text fields or photos.

What happens without an internet connection?

The app keeps a bounded local cache of queried products and can show those data later while offline. Products that are not cached cannot be queried until the connection is restored. Contributions require a connection to be submitted.

Which languages are supported?

The interface and product features are available in Spanish, English, German, French, Italian, and Portuguese, depending on the language configured on the device.

What accessibility options are available?

The app includes a color-blind-friendly palette, a high-legibility font, and configurable text sizes. It also provides accessibility labels and text for interface actions and information.

Privacy

VeganLens includes no analytics, advertising, or tracking. Ingredient analysis and OCR recognition run on the device. Scan history, favorites, and the product cache are stored locally.

See the English privacy policy for details about local data, public database queries, and contributions.
