European PII Redaction. /

Open-source SDK that detects and redacts structured PII across 31 European countries. Available for Python and Node.js. Local-only and deterministic — the SDK makes no network calls.

lockRules engine onlyRuns entirely in this browser tab — no cloud tier, no network call, no text leaves your device. Names and addresses are not detected here: those need the cloud tier, which has not launched.

/Input — auto demo running · type to take over

Declared Netherlands. Every country’s patterns still run — since 0.3.2 the setting decides how a match is labelled, never whether it is found — and anything attributed elsewhere comes back flagged out of scope.

The European PII Problem

Cloud API Risks

Sending documents to a third-party redaction API means personal data leaves your infrastructure — creating a new processor relationship and transfer surface under the GDPR.

Localization Gaps

US-centric tools miss European identifiers: BSN, codice fiscale, NHS number, and the national ID and IBAN formats used across 31 countries.

Slow Development

Building and maintaining per-country detection rules in-house is slow and hard to verify. Most teams ship late, or ship incomplete coverage.

Processing Architecture

Every stage runs on your infrastructure. The engine is deterministic; the same input always produces the same redaction.

The name is left in place — it needs the cloud tier at step 3.

Outside coverage

Not yet supported

The rules engine ships today across all 31 countries. Cloud coverage describes the contextual model still in development, which handles Dutch, English, French and German; a country counts as fully covered when every language its government and business documents are written in is among those. Minority co-official languages are out of scope.
