How can we help?
Questions, a wrong result, a missing product, or trouble with your subscription? We read every message.
Contact us
The fastest way to reach us is by email. Tell us your device, the app version, and — if it's about a specific product — the barcode, so we can reproduce it quickly.
We usually reply within 2 business days.
Common questions
A product shows the wrong ingredients or language+
Ingredient data comes from the open OpenFoodFacts database and improves over time. Switching the app language re-fetches the label in that language when the producer provides it. If something looks off, email us the barcode.
A product couldn't be evaluated+
If a product has no ingredient list (or none we recognize), Yllo can't judge it and won't show a verdict. This usually means the product isn't fully documented yet in the open database.
How do I manage or cancel Premium?+
Premium is billed through Google Play (and the App Store once available). Manage or cancel it from your store account's Subscriptions section; your access stays until the period ends.
How do I restore my purchase?+
Open the app, go to the paywall, and tap Restore Purchases while signed into the same store account you bought with.
How is my data handled?+
Yllo needs no account. Your scans and profiles stay on your device. See the privacy policy for details.
