Or if you use Whatsapp. Their privacy policy makes this pretty clear:
As part of the Facebook family of companies, WhatsApp receives information from, and shares information with, this family of companies. We may use the information we receive from them, and they may use the information we share with them, to help operate, provide, improve, understand, customize, support, and market our Services and their offerings. This includes helping improve infrastructure and delivery systems, understanding how our Services or theirs are used, securing systems, and fighting spam, abuse, or infringement activities. Facebook and the other companies in the Facebook family also may use information from us to improve your experiences within their services such as making product suggestions (for example, of friends or connections, or of interesting content) and showing relevant offers and ads.
Bizarrely, whilst general everywhere else, the policy specifically calls out banner ads to make it clear that they won't use them until they do, at which point they'll stop saying they don't:
No Third-Party Banner Ads. We do not allow third-party banner ads on WhatsApp. We have no intention to introduce them, but if we ever do, we will update this policy.
> We do not allow third-party banner ads on WhatsApp. We have no intention to introduce them, but if we ever do, we will update this policy.
I wonder how do they come up with this kind of language? Do they write a short text that gets filtered several times by multiple teams of lawyers and comes down to this? I cannot honestly imagine a sane human being writing such intricate bullshit, even on purpose.
