When you visit a website on an iPhone or iPad, snippets of data are stored on your device. Cookies and other cached data take a significant amount of time over time. Therefore, you may want to purge them. This is how it works:
Periodically deleting the data stored by iOS can be a good idea for a variety of reasons. Aside from the fact that these websites store a small amount of data on your devices, this data can also be used to track your visits. Web sites store cookies on their devices so you can identify them on your next visit, and while this may be beneficial if you stay logged in and save settings, not everyone will like it.
If you want to make sure sites can do this & # 39; If you do not keep track, you should also make sure that you delete the information stored on your device. If you do not have enough space, you may want to delete only the crumb.
Viewing and Removing Data
First, open the Settings app. Then tap on "Safari".
. Now scroll down to the bottom and tap "Advanced". Tap on "Advanced".
Then, tap "Website Data" at the top of the screen.
The next screen displays the websites that use the most data. To see everyone, tap Show All Sites. To clear all data for all websites, tap Remove All Website Data.
However, if you only want to remove the data for one site, swipe left and then tap the "Delete" button. (Clear).
Even though iOS may erase some of this data during its normal cleaning activities, if a device does not have enough disk space it is always a good idea to keep track of the data stored on your iPhone or iPad. This is one way to do just that, and we think you'll be surprised how quickly the total data volume swells.
