Advantages and Disadvantages of Deleting Cookies:
You can gain some speed by removing them and, at the same time, protect your privacy, because the information about your past browsing sessions are eliminated. But, since cookies save your login formation, it may be slower when you are logging in to websites or access cached data.
Important Things that You Need to Know:
(1) Besides Safari, if you have used other browsers, they will maintain their own cookies.
(2) Do a backup first because the deletion is permanently and even iOS Data Recovery can not retrieve the deleted files.
Well, now we will introduce this software, iPhone Data Eraser. You can use it to clear cookies on your iPhone when selling your handset, suspecting you have a malicious cookie or feeling the device is running slow.
Download the program first and follow the guide.
You are going to see two ways to do this:
Step 1. Connect the iPhone to PC
You may see this when launching the application. It means that connection has failed. Usually the way to fix it is to go to your phone and tap "Trust". Then the computer can reach the files on the handset. If that does not work, you can try changing a USB cord.
The next interface is like this, showing the some information of the phone. Choose "Erase Private Data".
Simply press "Start Scan" to get iPhone Data Eraser going.
Step 2. Choose Items and Erase Them
The scanning result is as below. Click "Safari Cookies" and you will see the details. After that, tick it and tap the button "Erase Now".
It may sound complicated, except it is not. You only need to click several times and type a few letters. The details involved will be explained clearly.
Step 1. Start to Wipe iOS Cookies
When connection is done, choose the mode "Erase All Data". You can now decide which security level is to be used. Or, you can just leave the setting by default. Though "High level" is based on the U.S DoD 5220.22-M, it costs more time. So, "Medium" is recommended. Then, type in the word "delete" to confirm you will to wipe the files and press the button "Erase Now".
Step 2. Understand the Erasure
In the second step, nothing needs to be done. All is automatic. It is divided into two parts. In the first part, the software clean up the information on the phone, including cookies, photos, messages, and so forth.
And then, your device will restart.
In the second part, free space of the iPhone will be totally cleaned so that old data can not be recovered. It is over when the program says "Completed". (You can only delete cached music and movies in the apps with the free trial version.)
