I had a new phone delivered in the post today, I have just spent the last hour setting it up and downloading 2 apps from google play, Duolingo (to improve my German) and Spotify. While waiting for my offload playlists to download I browsed ebay for a watch dial, I then popped onto to facebook, where I saw an ad for ebay on my homepage showing me the watch dial I just looked at, fair enough I thought, cookies can follow me around, but I wanted to turn tracking ads off so I went into the settings and I had the option of choosing the type of ads I can see, one option was to see ads based on my interests, and which two interests did it show me? Duolingo and Spotify!

Now ads based on my internet browsing is one thing, but facebook knowing what I had downloaded on a phone I bought today is seriously worrying.
