Cookies set via Addthis buttons

richard.beaumont Mar 09, 2012 04:07AM EST

A new law in the EU requires websites to determine what cookies get set when visitors go to their site, and also to declare what they do.

I am advising clients on this and a number of them have various of your buttons on their sites

We have identified the following as addthis cookies, set as third party when visiting sites with addthis buttons:


di
dt
loc
psc
ssc
ssh
sshs
uid
uvc

and there is another that is a first party cookie, but may also come from you:
_atshc

Can you provide documentation about what data these cookies collect and how it is used? Otherwise I will need to advise clients that they should consider removing the buttons from their sites.

Many thanks, Richard

Hi Richard,

This is a list of AddThis cookies and what they do:

loc - This is our geolocation cookie, so our publishers know approximately where people sharing information are located
Coyote-2-a0f0083 - This is our load balancer cookie
bt - A behavior targeting cookie
ana_svc - a real-time service cookie
phpbb3_* and style_cookie - These are set by our support forum software
__utm* - Google analytics tracking
uid/uit - User id and login time tracking
psc - View counter cookie
di/dt - Date tracking cookies for determining expiration of other cookies
ssh/sshs - Service share history, used for configuring our preferred services.

You can disable cookies by using this code:

<script type="text/javascript">
var addthis_config = { data_use_cookies:false }
</script>
