When you consult BRGM websites, connection markers called "cookies" are placed on your computer, mobile or tablet. They are used for audience measurement purposes.
The data collected (geographic area, pages visited, time spent, etc.) is recorded and kept on BRGM's servers for a maximum period of thirteen (13) months.
This information is strictly anonymous and does not enable users to be identified or to monitor their browsing of other sites. The information collected is only used to analyse BRGM site visitor use.
