Telemetry

There is no telemetry.

We don’t collect usage data, error reports, performance metrics, IP addresses, install events, country, user agent, or anything else. The redaction engine has no telemetry hooks. The web UI has no telemetry hooks. The installer has no telemetry hooks.

The only outbound request the product can make is the optional, opt-out update check — see What leaves your machine.

Why this page exists

Most software has a “we use only essential telemetry” page. We wanted to be very clear that this product has none. If you came here looking for a privacy policy line item to copy into your firm’s vendor-review checklist:

anonymizer does not collect any user data and does not send any usage information to its developers. The only optional network request is a version check against anonymizer.site/version.json, which can be disabled via the ANONYMIZER_DISABLE_UPDATE_CHECK environment variable.

How we know this stays true

  • tests/integration/test_no_network.py — a regression test that fails if any socket opens during processing
  • Open source — the full Python source is published as sdist on PyPI alongside the wheel. You can read every line.
  • No tracking dependencies — the dependency tree is published on the licenses page. None of the listed libraries do tracking.

If the situation ever changes, it will be a major version bump (1.x → 2.x) and called out in the changelog under a “BREAKING” header.
