Why am I seeing ads?
Occasionally, you may see advertisements for other companies in Skype (if you're using Skype without paid services, such as Skype Credit or a Subscription). Advertisements help keep Skype free for millions of users, and these advertisements will not disrupt your Skype experience in any way.
To provide ads that are of greater interest to you, we may use non-personally identifiable Skype profile information (including profile information from a linked Microsoft account), such as age, gender, country of residence and language preference, as well as other information Microsoft Advertising collects outside the Skype software.
How do I turn off ads?
If you have purchased some Skype Credit or a subscription, you will not see advertisements for other companies in Skype.
