Clearing Safari website data does not delete everything - iPhone

I've experienced the same thing with these "super-cookies". The only way I found to remove them was to reset the iPhone. I'm currently using an iPhone 7. I've tried the ways of removing the cookies, swipe delete and remove all button, unfortunately and those won't always work. I'll keep in touch to see if an answer pops up. :)

I just updated also and it did not delete my 0 byte history. What started as one just keeps growing to a long list. Some I have no clue what they are. Now I am afraid with this new update there will only be more problems to come. I am really getting fed up with Apple!

I upgraded my iPhone 6 Plus to 10.3.2., today. This cleared out my three permanent cookies. So far, I have been able to use Safari and delete all website data. I continue to test and will report if problem re-appear. Happy so far!

The iPhone update deleted the original three permanent website data but the issue did return on one website visited at weather.con. I was able to delete weather.com data by going back to weather.com then going to settings to delete the "non-zero bytes". and the associated data. However, I had to do it "manually" by sliding my finger left not with the delete all data function. You can then go back to Safari and deleted all the weather.com bookmarks still there. I haven't seen it come back anywheres else. I don't think the update fixed 100% but seems much better so far.

I feel your pain. I wish Apple would address this situation. It concerns me as much as to what a janky cookie could do but more concerning is Apple's unwillingness to solve what could become a real problem simply because they weren't keeping house...

Yeah...not sure they read it 😕 Good for you but not for so many others like me still with the issue

Nothing has been done so far.

I updated but the 0 bites cookie

doesn't go away with any tricks I read so far

It's a problem!

Maybe I'm saying the same as the other members of this group, maybe not.

I once did a test that worked and the data was empty.

I left the cookies allowed and visited the URL that was zero bytes with the safari.

I returned to settings and cleaned the history.

To my surprise, everything was empty.

I did not even have time to celebrate, because days later the problem came back.

Hey, apple? Can not or will not help us?

Yes! The last OS updated fixed it but temporarily. There seems to be some com web sites that are more prone to leaving permanent cookies/data (sprint; weather and CVS sites) than others. TS thinks that it won't be fix until iOS 11 comes out in the Fall. He uses the FireFox browery over Safari and surfing in private mode. Looks like Apple is going to try our patience for awhile longer.

Still an issue after last update (iOS 10.3.2). List of "super sticky cookies" is starting to get long. Sites that I never have visited.

Those sites have 0 bytes of data noted. Just weird that they are there. Like how and why?

Hopefully Apple will eventually address this hiccup before it becomes more than an annoyance.

The way I fixed it is to go to the safari settings > always block cookies> back > advanced > JavaScript off > website data > clear > JavaScript on > cookies allowed from websites I visit.

SOLUTION:

I too have struggled with this and like to clear cookies and browser history on a regular basis, only to be stumped by this bug. But after loads of online searching I found what is the ONLY ONE current solution currently available.

Go to finder.

Click Go.

Whilst in this menu hold down the options key.

Go to Library.

Go to Safari folder.

Then databases folder.

Remove corrupted folders.

That's all well and good, I suppose, but it isn't a solution to the original poster's problem. Their issue is with an iPhone.

Same problem occurs on the Mac OS X version of Safari.

If you're having a problem with your Mac, you should post in the relevant Mac forum. Mixing up operating systems is causing confusion in this thread. And, as it is a completely different operating systems, though the symptoms may be the same, the underlying problem probably is not.

I I spoke with an Apple senior tech named Lou. He reports that Apple programmers are aware of this issue but haven't given it a high priority yet since the number of complaints is too small to make it a top priority. They suspect it may be the iPhone users issue not there's. I disagreed and explained all my reasons which he seemed willing to consider. His iPhone has individual data that are persistent by design because he uses certain apps like HBO which helps it load faster. Still, he is able to deleted manually by sliding left on the data under the Safari>Advance>website delete manual function. We tried several other backdoor options but none worked. It's possible that by Apple OS version 11 this summer correct. I suspected Safari needs fixing not the OS and some websites may be aggravating this issue by deliberately programming in persistent data around Apple delete function. Lou was willing to consider alll this and pass up the line. Patience!

Right now it's more of nuisance. The sites that I have never visited contain 0 bytes of data. What concerns me are that sites not directly visited somehow are able to load something onto my iPad. Tecno Luddite ignorant idiot here. Guessing the process the sites use are a possible "door" for some ugly, unwanted malware to enter through.

One of the sites listed is rwrope.com. Just went to their webpage. An online retailer of rope. Do frequently visit the Sampson and New England rope websites. Wondering if either of those sites are the source of my sticky cookie?

Is it possible for a company to embed hidden cookies in the site you are visiting that then get stuck on your iOS platform?

No matter what, Apple needs to deal with this problem if it has any chance of being a leak to allow malicious software onto your hardware. OS and iOS flaw = opportunity for the poo heads out their.
