Behind Metriqual: zero. Here’s how.

Tokens

The model needs the question. It never needs the customer.

Customer data goes in. Only tokens reach the model.

PAN, Aadhaar, UPI IDs and phone numbers become tokens like [PAN]. Injections and anything your policy forbids never get past the gateway.

Every swap and every block leaves a line in the record.

Every redaction and every block, on the record.

Each row names the rule that fired and is hash-chained to the one before it, so no row can be edited without showing. The log holds types and hashes, never the data.
