# Handle Sensitive Data

> Minimum-safe practices for content submitted to and returned by a sensitive-data system.

Detection inputs and findings can themselves contain sensitive information.
Apply the same data-handling discipline to the analysis path that you apply to
the source system.

## Minimize exposure

* Send only the content required for the analysis.
* Avoid copying raw content into logs, traces, support tickets, or metrics.
* Restrict access to inputs, findings, and retained evidence by purpose.
* Define retention and deletion behavior before enabling durable storage.
* Use synthetic or redacted examples for development whenever they preserve the
  behavior under test.

## Preserve text integrity

When a result identifies a span, retain the declared encoding, normalization,
and offset unit alongside the source text. Transforming text after analysis can
invalidate offsets and cause a finding to point at the wrong bytes.

## Treat failures explicitly

Design callers for timeouts, unavailable producers, unsupported media, rejected
inputs, and partial results. A secure integration fails visibly; it does not
silently treat an incomplete analysis as clean content.

<Warning>
  Never include credentials, customer data, or production-sensitive payloads in
  documentation examples or issue reports.
