Common questions about using Blacklabel.

How do I delete my account and data?

Open the app → Settings → scroll to the bottom → "Delete my account". This immediately and permanently removes your scan history, household profiles, and contributions. This action cannot be undone.

How do I cancel my Premium subscription?

Subscriptions are billed and managed by the App Store or Google Play, not by us — we can't cancel it on your behalf. On iPhone: Settings app → your name → Subscriptions. On Android: Play Store app → profile icon → Payments & subscriptions → Subscriptions.

Where does the product and scoring data come from?

Ingredient, additive, and nutrition data comes from Open Food Facts, a free, community-maintained database. See the app's Settings → Data Sources page for details on how each score is calculated.

I found a bug or a wrong product score

The fastest way to reach us is to leave a review on the App Store or Google Play listing — we read every one and use them to prioritize fixes.

Is this medical advice?

No. Blacklabel's score is based on public ingredient and nutrition data only. Always consult a qualified professional for health decisions, and check a product's official packaging before relying on information shown in the app.
