The French privacy regulator CNIL recently issued official notices to two French data companies: Fidzup and Teemo. CNIL said that both companies were non-compliant with consumer consent rules under the General Data Protection Regulation (GDPR) and French privacy law.
Both are location intelligence vendors that work with retailers and brands on online-to-offline advertising and measurement. Both companies have SDKs that help them collect persistent location data from partner apps. App publishers are paid for their location data (and other data) by companies such as Fidzup and Teemo. This is a common model in the US market and outside the US, as in this case.
