• Amazon has been hit with a record $887 million EU fine by Luxembourg's data protection authority.
• The authority says Amazon's processing of personal data didn't comply with EU rules.
• Amazon said it would defend itself "vigorously" against the decision, which was "without merit."

Amazon has been fined €746 million ($887 million) by Luxembourg authorities for violating EU privacy rules.

Luxembourg's data protection authority, the Luxembourg National Commission for Data Protection (CNDP), imposed the record EU fine against Amazon Europe on July 16, per an SEC filing on Friday by the tech giant.

The CNDP claimed that Amazon's processing of personal data for advertising did not comply with EU General Data Protection Regulations.

Amazon said it would appeal.

"The decision relating to how we show customers relevant advertising relies on subjective and untested interpretations of European privacy law, and the proposed fine is entirely out of proportion with even that interpretation," an Amazon spokesperson told Insider.

The company said in the SEC filing: "We believe the CNPD's decision to be without merit and intend to defend ourselves vigorously in this matter."
