What happens to your data

Guide

A lifecycle view of every kind of data a brand shares with Heavy Metal Tested & Certified: who holds it, whether HMTc can access it, whether it is public, and the basis on which it is retained. Exploratory results stay in your custody by default; only conformity status becomes public.

What happens to your data

Different data plays different roles across a certification, so it is held differently. The table below states, for each kind of data, who is the primary custodian, whether HMTc can access it, whether it becomes public, and the basis on which it is retained. The governing principle is simple: exploratory and readiness data stays in your custody by default, and only a certified product’s conformity status is published.

No central repository of your raw results

HMTc retains the conformity evidence it needs to make and stand behind a certification decision. It does not aggregate brands’ raw exploratory test data into a central, searchable repository. Where category learning is useful, it is drawn from de-identified, aggregated data under minimum-cell-size controls.

De-identification is a governed method for limiting the risk of re-identification. It is not an absolute promise of anonymity, particularly where a product category, an origin, a formulation, or a supplier is distinctive enough to narrow the field. The correct standard, following the way bodies such as NIST describe it, is disclosure-risk management under governance, not a guarantee that a record can never be linked back. HMTc treats it that way and says so, rather than promising more than de-identification can deliver.

What is public, and what is not

A product becomes public when it is certified, or when an existing public certificate must change status under the published rules. Requesting a standard, running a readiness review, or working a correctable finding does not create a public record, and HMTc does not maintain a public list of brands that applied but were not yet ready to certify.

What custody does not do

Custody and confidentiality are commercial and operational controls. They are not attorney-client privilege, and they are not a promise that relevant evidence can never be reached through lawful process. They do not override a reporting, recall, disclosure, or safety obligation, and they do not permit use of the mark on a nonconforming product. A brand with a specific legal exposure should structure privileged work through its own counsel. See For legal & QA for how the certification record behaves under challenge.
