On May 12, 2022, the European Data Protection Board published guidelines with a methodology for calculating fines for violations of the General Data Protection Regulation (GDPR). These guidelines were subject to a public consultation until June 27, 2022. Because these guidelines are likely to have an influence on future decisions by data protection authorities in the European Union, Keller and Heckman LLP has developed DeFine, a GDPR fine calculator tool based on that methodology. It is accessible online and free of charge.
