Comuto SA (“BlaBlaCar”, “we”, “us”, or “our”) uses cookies and similar tracking technologies on our website, our electronic communications and mobile applications (individually referred to as “platform” or jointly as “platforms”). In this Policy (the “Cookie Policy”), we provide you with more information relating to these technologies and about the choices you can make.
1 – What is a “cookie” and what are “similar tracking technologies”?
A “cookie” is a small text file that is stored and/or read by your web browser on the hard disk of the device you are using (e.g., desktop computer, laptop or smartphone) by websites you visit. In addition to cookies, BlaBlaCar also uses similar technologies for tracking including “pixel”, “tracking scripts” or “software development kits” (known as SDKs). They are small transparent image files or lines of code contained in our website, our electronic communications (emails for example) and mobile apps, which record how you interact with them. All these tracking technologies are referred to as “cookies” in this Cookie Policy.
2 – Who places cookies on our platforms?
Cookies on our platforms are placed either by us (“so-called “first-party cookies”) or by our partners (so called “third-party cookies”) as data controllers. Third-party cookies can be used for displaying certain personalized advertisements as further described below. BlaBlaCar does not manage the cookies of these partner companies and has no control over or responsibility for these cookies or the use of the data collected through them.
