The fact that each device has an IDFA that any app can share with literally anyone in the world, without the need to tell you, because IDFA is a quasi-persistent identifier I suppose doesn't matter.
- codetrotter 8y agoFirst time I've heard of this. It is possible to turn it off though. > note that when ad tracking is limited, the value of the advertising identifier is 00000000-0000-0000-0000-000000000000 https://developer.apple.com/documentation/adsupport/asidentifiermanager https://developer.apple.com/documentation/adsupport/asidenti... Here is how you turn it off: 1. Go to Settings > Privacy > Advertising. 2. Turn on Limit Ad Tracking. https://support.apple.com/en-us/HT202074 https://support.apple.com/en-us/HT202074
- FridgeSeal 8y agoSome FUD here, both Android and iOS (and Windows Phone, when it was a thing) have these advertising identifiers. Both platforms allow you to disable tracking and/or reset the identifier to something new. However, if you disable tracking on Android, it just changes the value of another variable called (to the effect of) "Ad tracking enabled" and you are politely asked to not "target ads" towards that ID. It's important to note here, that nothing ever stops you, you're just asked to. You can still harvest data, you can still analyse and sell it, but you just can't advertise back to them. In comparison, disabling Ad tracking on iOS gives you the zeroed out advertising ID (which is shared with everyone else who opts out, which means you blend into the crowd (which makes that data more difficult to usefully separate and analyse). Pretty sure Apple doesn't let you bundle dozens of Advertising SDK's that harvest everything by default either.
