Language Support

PasteGuard supports 24 languages. The language is auto-detected from your input text. Available languages: Catalan, Chinese, Croatian, Danish, Dutch, English, Finnish, French, German, Greek, Italian, Japanese, Korean, Lithuanian, Macedonian, Norwegian, Polish, Portuguese, Romanian, Russian, Slovenian, Spanish, Swedish, Ukrainian

​
Docker Images

Languages are auto-configured per image — no config changes needed:
  • :en image → English only
  • :eu image → English, German, Spanish, French, Italian, Dutch, Polish, Portuguese, Romanian
For custom languages, build locally: 
LANGUAGES=en,de,ja docker compose up -d --build
If only one language is configured, language detection is skipped for better performance.

​
Confidence Scoring

Each detected entity has a confidence score (0.0 - 1.0). The default threshold is 0.7.
  • Higher threshold = fewer false positives, might miss some PII
  • Lower threshold = catches more PII, more false positives
pii_detection:
  score_threshold: 0.7

X-PasteGuard-PII-Detected: true
X-PasteGuard-PII-Masked: true   # mask mode only
