Each test stamps its answer on the bar, so the result reads at a glance.

How many hops to the nearest mixer?
Is it named in a public theft report?
Is it named in a public scam report?
When was it first seen, and how steady since?
Exchanges, services or unknowns?
Assay reads what anyone can look up, and nothing else.
A score is a risk signal, not a legal finding.

Public data only: the transaction history any block explorer shows, sanctions lists that publish crypto addresses, and public reports of thefts and scams. It works on transparent blockchains such as Bitcoin, Ethereum and Tron. Privacy coins such as Monero hide their history, so they cannot be scored this way.
No. Assay has no access to wallets, keys, exchange accounts or anything behind a login. It shows what the public record says about an address, including labels that are already public, such as a known exchange. It does not unmask a private person.
Reports are saved on your PC and go nowhere until you hand one over yourself. To score an address, the app looks it up in the reputation database, the same way a block explorer is asked about an address.
Reading a public blockchain is what anyone can do by hand in a block explorer. Follow each source’s terms and your local law, and do not use Assay to harass or expose anyone. The score is a risk signal, not a legal finding, and not a substitute for a compliance check where the law requires one.
