Developer Tips: What’s the deal with MAC addresses?
If you are a developer or app publisher, what is the big deal with accessing a unique identifier like a device’s MAC address anyhow? Also, if you are not collecting unique identifiers in your app, is it your responsibility to know every little thing the SDKs within your app are collecting (with or without your direction)? The answer is yes: even if you didn’t write the code within the SDKs that your app uses, they are still part of your app from both a legal and practical perspective, and therefore you’re responsible for their behavior within your app. If prohibited identifiers are being collected by SDKs within your app, you could be held liable.
