PLOS Cookie Policy

Updated on April 27th, 2022

INTRODUCTION

We are the Public Library of Science (“PLOS”).  This Cookie Policy describes the types of cookies and other tracking technologies we use on the PLOS website, our purposes and basis for using them, and your choices regarding them. 

If you have questions about this Cookie Policy, please contact us at privacy@plos.org or send mail to:

COOKIES AND OTHER TRACKING TECHNOLOGIES

Background

PLOS and our third-party partners, such as analytics and advertising partners, use cookies and other tracking technologies to collect certain information.  Cookies and other tracking technologies are used to distinguish you from other users on the PLOS website. This helps us provide you with a good experience when you browse our website and allows us to improve our site, analyze the use of our site, and deliver targeted advertising based on your browsing history on our site and other websites.  A cookie is a small file of letters and numbers that are stored on your device.

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.

Legal Basis for Use of Cookies

PLOS uses cookies under the following legal basis:

  • PLOS’s legitimate interests (for users in the EU: Art. 6 (1) (f) GDPR). We use strictly necessary cookies based on PLOS’ legitimate interests. This includes:
    • to enable PLOS to provide our products and services to you, including website features
    • the legitimate interests of others, for example, to ensure the security of our website
    • to prevent fraud and other illegal activity.
  • Consent (for users in the EU: Art. 6 (1) (a) GDPR). We place optional cookies on the basis of your consent, which you may withdraw at any time after giving it, as described in this Cookie Policy. 

For users in the EU: The US is assessed by the European Court of Justice as a country with an insufficient level of data protection.  If you consent, you agree in accordance with Art. 49 (1) (a) (GDPR) that your data may be processed outside the EEA, including in the United States.

How to Manage Cookies 

Withdrawing Consent

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. 

Browser Settings 

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.

“Do-Not-Track”

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.
