COOKIES AND OTHER TRACKING TECHNOLOGIES
PLOS uses both first party and third-party cookies. First party cookies are served directly by us to your computer or device. Third-party cookies are served by a third party on our behalf. Cookies can be “persistent” or “session” based. Persistent cookies remain on your device after your browser is closed. Session cookies are deleted automatically once your browser is closed. PLOS uses both persistent and session cookies.
We also use technologies that are similar to cookies, such as tags and pixels. Tags are small portions of code which we use on the PLOS website to learn whether you have clicked on certain web content. A pixel is a similar type of technology used on the PLOS website for the purpose of counting the number of views for each of its published articles. Pixels are sent directly to our servers or to the third-party platform which has provided the pixel.
For the rest of this policy, “cookies” refer to both cookies and other tracking technologies.

How to Manage Cookies
If you do not wish to accept optional cookies in connection with your use of the PLOS website or wish to withdraw your consent, you can opt out by clicking on Cookie Preferences.
To opt-out of our use of necessary cookies, you can change your browser settings to stop accepting cookies or to prompt you before accepting cookies from websites you visit. You can delete cookies in your browser settings at any time. Please note that by not accepting cookies, some pages may not fully function, and you may not be able to access certain information on the PLOS website.
PLOS does not track users over time and across third party websites to provide targeted advertising and therefore does not respond to Do Not Track (DNT) signals. Third parties that have content embedded on the PLOS website such as social sharing features may set cookies on a user’s browser and/or obtain information about the fact that a web browser visited a specific PLOS website from a certain IP address.
