About cookies

Like most digital marketing platforms, mediarithmics uses "cookies" to enhance the user experience on the web, to deliver more relevant ads and for ad reporting. mediarithmics cannot use these cookies to personally identify you in any way, and these cookies in no way damage your system or files.

A mediarithmics cookie is a unique number that is assigned to your browser the first time mediarithmics serves your browser an ad or identifies your browser on a client's website. This number is stored in a file on your computer and helps us deliver relevant ads to you.

For instance, cookies help mediarithmics ensure that you don't repeatedly see the same advertisement. Cookies can also help advertisers measure how you utilize an advertiser's site and the effectiveness of an advertisement. This information can then be used by advertisers to better identify your needs and show you ads related to the type of products you might be interested in.

Although mediarithmics believes that cookies help enhance your experience on the web by delivering more relevant messages to you, mediarithmics does not need cookies to deliver ads to you. If you decline a mediarithmics cookie, you will still be able to view ads; however, you may see the same ad repeatedly or be delivered ads that have no relevance to you.

Data Retention - How long is data stored?
