*Updated October 23, 2020

Our ON24 Platform, which includes services related to Webinars, Virtual Environments, Engagement Hub, and ON24 Target (collectively, the “Platform”) uses cookies to operate and improve our Platform and to provide you with a secure and positive experience when you use our Platform. This Platform Cookie Policy applies to our Platform and provides you with information about the types of cookies our Platform uses and the purposes for using those cookies.

Please read this Platform Cookie Policy carefully for more information about why we use cookies and your choices regarding cookies on our Platform.  For a list of all the cookies used on our Platform, please review our cookie list below.  For further information about this Cookie Policy, please contact privacy@on24.com.

What is a cookie?

A browser (or HTTP) cookie is a small file of letters and numbers that is transferred to your browser through our Platform. Cookies allow us to operate and secure our Platform, remember users who are logged in, understand how users navigate through and use our Platform and associated services,  and to display personalized content and targeted ads on our Platform and on third-party sites and online services.

Types of cookies First and third-party cookies: whether a cookie is ‘first’ or ‘third’ party refers to the domain placing the cookie.

First-party cookies on our Platform are those set by the ON24.com domain.

Third-party cookies on our Platform are cookies that are set by a domain other than that of the website being visited by the user. If a user visits a website and another entity sets a cookie through that website, this would be a third-party cookie.

Persistent cookies: These cookies remain on a user’s device for the period of time specified in the cookie. They are activated each time that the user visits the website that created that particular cookie.

Session cookies: These cookies allow website operators to link the actions of a user during a browser session. A browser session starts when a user opens the browser window and finishes when they close the browser window. Session cookies are created temporarily. Once you close the browser, all session cookies are deleted.

What cookies do we use and why?

'Necessary’ cookies let you move around the Platform and use essential features like secure areas and login screens. Without these cookies, we cannot respond to your requests or provide you with the services you request or access on our Platform. For example, we use these cookies: to remember information you have entered on forms during a web browser session; to identify you as being logged into our Platform; for security purposes; and to route users to specific applications of a service, or specific servers.

These cookies are necessary to the proper functioning of the Platform, so if you block these cookies the Platform may not function properly.

‘Performance’ cookies collect information about how you use our Platform (e.g., which pages you visit and if you experience any errors). They are used to help us improve how the Platform works, understand the interests of our users and carry out Platform analytics, test different designs and features; and measure the effectiveness of our advertising.  Some of these cookies are managed for us by third parties.   

‘Functional’ cookies enable us to provide enhanced functionality and personalization.   For example, we use these cookies to provide certain features (such as embedded content); improve your visit; remember settings you've applied, such as language, layout, text size, preferences, and colors; save your cookie preferences, and remember if you have engaged with particular content on the Platform so that we don’t show it again. Some of these cookies are managed for us by third parties.

Google Analytics is a web analytics service provided by Google, Inc. (“Google”). Google uses cookies to help us analyze how users use the Platform. The information generated by the cookie about your use of the Platform (including your IP address) will be transmitted to and stored by Google on servers in the United States. In case of activation of the IP anonymization, Google will truncate/anonymize the last octet of the IP address for Member States of the European Union as well as for other parties to the Agreement on the European Economic Area. Only in exceptional cases, the full IP address is sent to and shortened by Google servers in the USA. On behalf of the Platform provider, Google will use this information for the purpose of evaluating your use of the Platform, compiling reports on Platform activity for Platform operators, and providing other services relating to website activity and internet usage to the website provider. Google will not associate your IP address with any other data held by Google. You may refuse the use of these cookies by selecting the appropriate settings on your browser as discussed in this notice. However, please note that if you do this, you may not be able to use the full functionality of this Platform. Furthermore, you can prevent Google’s collection and use of data (cookies and IP address) by downloading and installing the browser plug-in available under https://tools.google.com/dlpage/gaoptout?hl=en-GB.

Further information concerning the terms and conditions of use and data privacy can be found at http://www.google.com/analytics/terms/gb.html or at https://www.google.de/intl/en_uk/policies/.
