Regex Tester & Validator

Matches German legal phrases like 'Verantwortlicher gemäß Art.' (responsible party pursuant to Article) at the start of a line. Handles umlaut/ASCII variants (ä/a, ß/ss), common abbreviations (gem., Art., Artikel), optional periods, and flexible whitespace. With case-insensitive and multiline flags, it's ideal for extracting data controller sections from German GDPR privacy policies or Impressum pages.
