JD can now pull a score describing your internet behavior from the phone company tied to your number, and use it to target what it shows and sells you. This brings in information about you from outside JD's own apps and website — data JD could not see before. JD says the score is de-identified and cannot be traced back to you, but the text does not say what goes into the score, how long JD keeps it, or how to say no. The policy treats your acceptance of this privacy policy as your authorization, and it does not describe any way to withdraw it separately.
“您同意并授权我们向您**手机号**对应的通信运营商查询您的上网行为模型分值,以便于识别您可能需要的商品或者服务。”
What you can do — If you do not want this, ask JD directly about it through the help.jd.com online customer service system or JD's customer service phone lines listed in the policy. The policy also points to itemized privacy settings in the app under "我的-账户设置-隐私设置", though it does not say this specific carrier query can be turned off there.
