Saved decisions / history

Saved checks live in a private history.

Keep recent checks, compare-later decisions, products you are avoiding, proof gaps, source notes, and items that need more documentation in one place.

Proof standards

A calm standard for deciding what deserves trust.

Every check separates product facts, label claims, source quality, proof freshness, and unresolved uncertainty. The goal is not to declare everything safe or unsafe. It is to make the evidence easier to inspect.

01

Supported claims stay specific

A stronger result should connect the claim to the product, ingredient, source, or proof document in front of you. Broad marketing language does not get treated as evidence.

02

Missing proof stays visible

If testing, sourcing, freshness, dosage clarity, or claim support is not visible, the result should say so plainly instead of filling gaps with confidence.

03

Qualified contributor context stays separate

Reviews, source notes, and qualified contributor context can improve a check, but they stay separate from product facts and proof documents.
