The $50/Year Subscription Trap for Food Allergies

For millions of people living with Celiac disease, nut allergies, or sensitivities to petroleum-based food dyes (like Red 40 and Yellow 5), reading ingredient lists is a matter of daily health and safety.

Unfortunately, modern food apps have locked custom dietary filtering behind expensive $50 to $70 yearly subscriptions. Worse, they require you to create accounts, hand over your email, and track your shopping history.

UnwrapTruth's Core Philosophy: 100% Free & Zero-Login

You should never have to pay a subscription or compromise your personal privacy just to know if a snack contains peanut traces or canola oil.

How Private Client-Side Preferences Work

UnwrapTruth stores your dietary profile directly inside your browser's private local storage. No server database ever stores your health restrictions or ties your dietary needs to an identity.

Whenever you scan or search a product, our engine evaluates the ingredients locally against your preferences in milliseconds. If safe, you see an emerald '100% Safe' badge. If any ingredient violates your filter, an itemized warning alerts you immediately.

Frequently Asked Questions

Will my filters stay saved if I close my browser?

Yes! Your preferences are persisted in your browser's secure localStorage and remain active until you clear your browser cache or change them in the 'My Diet' modal.

Can I use multiple dietary filters at the same time?

Absolutely. You can select any combination—such as No Seed Oils + Gluten-Free + Vegan—and UnwrapTruth will flag any ingredient violating any of your active selections.
