In this case, the app has been maintained and updated normally since version 1.0. The corresponding paid in-app purchase items were added to version 2.1, and the app display map was updated. During the review process, the problem 5.4 appeared and has not been solved. Many email complaints have not been responded to. First of all, our app does not collect user data, and we don’t know how to obtain user consent, nor do we know how to make it clear to users how to use this information. We turned on the VPN channel just to speed up the network, but we don’t know how to solve this problem, and Apple’s review did not use a clear solution.
We noticed that the app did not obtain user consent before collecting user data.
We noticed that the app did not adequately explain how the app or VPN service uses the data collected from users.
To view and store information about users and the data they use, you must explain to users what data is being collected and how it will be used. In addition, you must obtain the user’s consent before uploading the data to the server. It is not enough to mention this information in the app’s terms of service or privacy policy.

If you just want to speed up the network instead of using traditional pure VPN applications, it is recommended to adjust the plan and then update.
