Yes, the use of Leadinfo is legal under the GDPR, which was introduced as a European privacy law on 25 May 2018.
Leadinfo matches the IP address of the visitor against a publicly available database of company data (such as the Chamber of Commerce). According to the GDPR, the IP address is considered to be private data, and there must be solid justification for its use. The justification is ‘own legitimate interest’, provided for in Article 6(1)(f) of the GDPR. This article states working with personal data is permitted if this serves a clear interest and privacy standards are maintained.
Marketing and analytics are considered to be legitimate interests, and Leadinfo only uses private data in a limited capacity. IP addresses are not saved and only publicly accessible corporate data is shared with the users. This means that Leadinfo maintains privacy standards. As a Leadinfo user, you are obliged to state these facts in your company’s privacy statement, as well as the register of data processing operations.
