iOS 10.3 Safari cookies won't delete

Is anyone having any issues with cookies in 10.3 Safari? Cookies don't seem to delete when I try to remove them using all the delete methods. Additionally, when I block cookies, cookies still get stored.


May be cookies settings have changed and I need to change something. Does anyone know?

I've had the same issue with being unable to delete a number of "0 Bytes" cookies on my iPad for a while, but recently an eBay.co.uk cookie of 508KB size began to exhibit the same behaviour - at which point I "snapped", enough is enough! I found a solution, however it's a little long-winded and requires a Mac:


  1. Connect the iOS device to a Mac and create a backup using iTunes
  2. Open the backup using an explorer/editor tool such as iBackupBot (I was a little dubious about using this at first, but it was signed by a registered developer and did not require installation nor did it ask for a password input at any stage, so pretty safe)
  3. Navigate to the folder "User App Files > com.apple.mobilesafari > Library > Webkit > Website Data"
  4. Delete all files and folders in the enclosed IndexedDB folder - this is where the 508KB of eBay data seemed to be
  5. Delete all files and folders in the enclosed WebSQL folder - where all the other "0 Bytes" cookies are stored. I was amazed there were even cookies in here which didn't show up in the Website Data view in Settings. Mine had a whole trove of cookies from argos.co.uk, ebay.co.uk, and uk.farnell.com amongst others.
  6. Restore the backup to your iOS device using iTunes


This was sucessful for me on both my iPad Pro and iPhone SE - both on iOS 10.3.3. I can't confirm if it will work for iOS 11 devices, but from what I've read many people have found the cookie problem to be fixed in 11.1.2.

That is when they want to remove Jessa Jones (iPad Rehab) post and ban her. As well as me and others.


Amazing that this website still has bugs when typing in it.

The only people who can delete posts or ban people are the Hosts, paid Apple employees, not rabid fans. They do the first when people violate the Terms of Use to which we all agreed when we signed up here. They do the second when people don't pay attention to the warnings they get when their posts are deleted.

Thank you for your observant suggestion. It seems they forget, it is the small things that you are often judged by. Usually these are for the benefit of third-parties but this one, I'm sorry, requires an internal resolve. It is now past unique and becoming a pest for all iPhone 6, users going through the esrly stages of performance degradation!

We find ourselves using fewer Apple made applications for reasons such as their disregard for privacy and User control over managing personal data such as cookies. There is zero urgency to resolve this issue which leaves us to believe it's part planned obsolescence, or Apple simply feeling more emboldened to ignore customer needs. Either way, because of this persistent issue, at my company and at home, Safari, FCP, Preview etc have all become apps of last resort.

You should always chose the tool that best meets your needs, not anyone else's.

The word “support” comes to mind, clearly Apple fail to appreciate customers with this predicament.

This forum is not Apple Support. This is a user-to-user technical support forum. If you wish a response from Apple, use the Contact support link at the top right of every page of these forums.



Although your iOS is quoted as iOS10,

I didn't list what version of iOS I have.

Im also having same issue on a IPhone SE (IOS 10.3.3) re persistent 0Kb cookies if Website data not deleting. Does anyone:

(a) know of a Windows solution eg some effective third party software? (Some software claims to be able to do this, but it will cost about 20- 50 USD to buy software !!! (and no guarantee it will do job)

(b) a solution in Safari/ on Phone itself. (All the answers seem to focus on Macs eg using Finder/ Databases etc and unfortunately Ive not got one). Some solutions say revisit the offending (cookie) website and allow cookies, then delete Website data with the cookie website open. However, this has not worked for me. Its been a very annoying process.


I dont want to upgrade to IOS 11.2 etc as its too heavy in battery etc and Im not sure if it will even resolve the problem.


If anyone can help with a or b that would be most appreciated.

As I only have PC's I will follow your procedure and report back.

However, like previous "solutions" the obvious issue remains unresolved.

Firstly, we all have paid Apple for an effective OS to fulfil its role and resolves commands operated by users.

Secondly, you may have fallen into an unfortunate trap. Having devised a solution it is, I regret, limited! You are required periodically, to return and repeat the process. In other words this is no "lifetime" solution. As I have repeatedly pointed out - despite a moderators attempt to claim otherwise - Apple's failure to resolve this issue makes the iPhone unfit for purpose and is a task Apple should fix. That said recent issues appear to be of far greater concern. They've had our money now is the time to fulfil their commitment - oh how I wish they would!

Thanks for the responses Ive received, but it seems the only potential solution is to upgrade to 11.2. Does anyone know if I upgrade to 11.2 (from 10.3.3). on an Iphone SE, will it have desired result eg removing zombie cookies? Also can anyone confirm if 11.2 has other undesirable problems - Ive seen many of those who have upgraded reported a range of other problems in 11.2 eg battery drainage and other bugs??


Please can you answer with reference to Iphone SE. Thanks


PS Does anyone know of apples email address for Support as cant find it anywhere

It seems a very drastic measure, enough to demonstrate to those in their "ivory tower" that their error - I assure you it is - have supplied a product unfit for purpose. You have to question how you would respond if the roles were reversed? Any solution, is the sole responsibility of the Operating System developer. They already protect themselves from loss of data and other consequences but they are completely responsible to ensure fitness for purpose. Why should users be compelled to undertake remedial action to circumvent developer failure? You may consider this to be a fruitless answer, perhaps Apple would like to contribute?

Jan 17, 2018 2:13 AM in response to bjgtab

Thanks for reply. Was your upgrade to 11.2 from an Iphone SE or another model? Any problems with battery drainage or any other significant problems? Also there seems to be a performance decline when upgrading to 11.2.2

eg see https://www.forbes.com/sites/gordonkelly/2018/01/09/apple-ios-11-2-2-release-sho uld-you-upgrade/#7147e64a65ec


Theres a suggestion to remain at IOS 10 for timebeing

Jan 17, 2018 2:17 AM in response to Ryanthered

@Ryanthered. Thanks for replying. When you say complete reinstall, did you have to set up a new Icloud account? If this is a complete reinstall, then how do you recover all your contacts, Apps, etc etc?? Or can you do a complete reinstall first, then restore from Itunes to a point previous point before cookies problems started?? IE you do *not* back up your phone first as this will also back up the problem.


If anyone has tried this method, please do share.

The thing is...

Every new iPhone means enhanced performance, supported by an upgraded OS taking advantage of new features. The downside: Apple fails to adequately support its predecessor, degradation is the inevitable casualty. The amount of "fixes" "work arounds" "did you try this" "this worked for me" - forums are full of it! The responsibility lies with Apple. There is a tornado of vultures just waiting to offer solutions and users ready to try anything to get their iPone working. In the end there is only one option! Smart phones arr evolving, technology too, perhaps budgeting for max 3 years, is the basis for your next upgrade, in the meantime we have to accept the inevitable.

I'm sorry but your observation is erroneous. I can validate all my remarks and support statements made. When a situation looses its integrity the issue moves from fact to fiction. I am able to prove all statements made. Your further comments must be qualified with facts likewise. A bug is a bug - I bought a device which has failed considerably, My investment was, for me, considerable, I expect it to function as specified. "Small bugs" cost lives, magnitude is irrelevant. No point in any further discussion as your arrogance is contradictory.

Further to the recent release the problem remains and it has increased. Last count was 15 x 0 Byte files. It is extremely frustrating that a miniscule error should have Apple's on its heels. As an an ex-systems programmer and developer, this is another failing of Apple.

Providing a file manager would, to me, have been an integral element of any OS - sorry iOS.

Would appreciate a prognosis, as a disabled owner I purchased my iPhone 6 Plus direct from an Apple store and I expect, rightly, that such a failure to easily be rectified.
