Settings for preventing privacy leakage in Pinduoduo: 1. Close the circle. When we open the Pinduoduo, we will find a small circle at the top of the homepage. In the small circle, we can see friends' order information and the goods they bought! Sometimes we even recommend the related products we bought to our friends. I have encountered a similar situation, and my friend asked me directly about the quality of the products we purchased! I'm depressed. It turned out to be caused by this small circle, so we have to close this small circle to protect our private information from being leaked. Open the Pinduoduo search settings, and then select the spelling settings. Then cancel the following permissions directly, and then click Close to spell a small circle. After it is closed, it can prevent our information from being leaked. Second, close personalized advertising in Pinduoduo. Find the frequently asked questions in Pinduoduo settings, and then click Personalized Recommendation and Advertisement to turn on Personalized Recommendation Management, and then turn off the personalized content recommendation switch below. After closing personalized recommendation, go back and click Personalized Advertising Management, and then close. After turning off these two personalized switches, we won't receive personalized advertisements and related information pushed by Pinduoduo when using Pinduoduo. Third, close Pinduoduo's mobile phone authority. When using Pinduoduo, in most cases, we will receive an invitation from this friend or ask us for help. In particular, cutting a knife is the most common, because Pinduoduo has read the permission of our mobile phone, and friends can find us through the address book, so we have to turn off this permission. Find the application settings on your phone, and then select Application Rights Management. After opening the application rights management, directly find Pinduoduo, and then set all the rights related to the mobile phone to refuse or ask.
