Is Apple Intelligence Safe? UK Guide
Apple Intelligence launched in the UK in December 2024. Here is what data it collects, what the ChatGPT link means, and how UK users can stay in control.
Quick summary: Apple Intelligence is broadly safe for everyday use on iPhone and iPad. Most features process everything on your device, so your data never leaves your phone. The optional ChatGPT connection sends your request to OpenAI when you agree to use it, though Apple negotiated stronger privacy protections than you get by going to ChatGPT directly. UK users also lost a specific iCloud encryption feature in early 2025 that is worth knowing about before deciding how much to rely on it.
Apple Intelligence has been available on UK iPhones since December 2024. You may have seen it appear in your Settings, noticed new buttons appearing when you type, or found Siri suddenly offering to help with your writing. If you are wondering whether to let it in, you are asking exactly the right question.
This guide covers what Apple Intelligence actually collects, where ChatGPT fits in, what changed for UK users' iCloud data in 2025, and how to switch things off if you prefer. No technical knowledge required.
What Is Apple Intelligence?
Apple Intelligence is Apple's name for a collection of AI features built into recent iPhones, iPads, and Macs. It arrived in the UK in December 2024 with the iOS 18.2 update.
Writing assistance is the headline feature: Siri can summarise emails and suggest replies, while a new button appears in any text field offering to clean up what you have typed. Notification summaries condense several alerts into one short line. An upgraded Siri now understands more natural questions and can take actions across your apps.
Most questions centre on the ChatGPT connection. When Siri receives a question beyond its own abilities, it can forward it to ChatGPT on your behalf. That is where the privacy questions start in earnest.
Apple Intelligence requires at least an iPhone 15 running iOS 18.2 or later. If you have an older phone, none of this applies to your device.
How Does Apple Intelligence Handle Your Data?
Most Apple Intelligence features run entirely on your device. Writing suggestions, email summaries, and notification condensing all happen on the phone's own chip. Nothing leaves your phone.
For tasks that need more processing power than your phone carries, Apple uses what it calls Private Cloud Compute. Your request is sent to Apple's own servers, handled, and the answer is returned to your device. We went through Apple's Apple Intelligence & Privacy legal disclosure to check what the company actually commits to in writing: data sent to Private Cloud Compute is not stored, and is not accessible to Apple staff. Independent security researchers have been given access to verify those claims, which is an unusual level of transparency for a technology company.
What Apple logs for its own records is minimal: approximate request sizes and how long each task took. None of that is linked to your name or Apple account.
You can see exactly how your requests are being handled. Go to Settings, then Privacy & Security, then Apple Intelligence Report. It shows a log of recent activity and whether each request was processed on-device or via Private Cloud Compute.
What Is the ChatGPT Connection?
Some requests are beyond what Apple's own AI can handle. For detailed factual questions, complex writing tasks, or anything that draws on broad knowledge of the world, Siri may offer to pass your question to ChatGPT instead.
It is not automatic. Every single time Siri considers using ChatGPT, it stops and asks your permission. You can decline. If you say yes, your request and any documents or photos you included are sent to OpenAI, the company that makes ChatGPT.
It is the only part of Apple Intelligence where your data leaves Apple's systems. Worth knowing before the prompt appears for the first time.
What Does the ChatGPT Integration Send to OpenAI?
When you agree to let Siri use ChatGPT, the following data goes to OpenAI, according to Apple's ChatGPT Extension & Privacy disclosure:
- Your request and any attachments, such as documents or photos
- Your general region (not your precise location)
- Your device type and language
- Your time zone
Your IP address is hidden from OpenAI. Apple acts as a relay so OpenAI never sees where your request came from.
Use ChatGPT through Siri without logging in to a ChatGPT account and OpenAI is not allowed to store your request or train future models on it. That is part of a commercial agreement between Apple and OpenAI. Stronger than what you get by going to chatgpt.com directly and not signing in.
Privacy journalist Kate O'Flaherty noted in Forbes that signing in to your ChatGPT account through Siri switches the arrangement: OpenAI's standard account terms apply, and they may retain your data. The sensible default is to leave the ChatGPT account disconnected unless you specifically want features like conversation history.
By default, the ChatGPT integration is off. To enable it, go to Settings, then Apple Intelligence & Siri, then ChatGPT. You can disable it from that same screen at any time.
What Changed for UK Users' iCloud in 2025?
Almost no consumer guide covers what happened to UK iCloud in 2025, and it matters.
In February 2025, Apple withdrew a feature called Advanced Data Protection from UK users. It had provided end-to-end encryption for photos, notes, iCloud backups, voice memos, and iCloud Drive files. End-to-end encryption means only you and your devices hold the key. Not even Apple can read those files.
After the UK government issued a legal order requiring Apple to allow access to encrypted user data, Apple removed Advanced Data Protection rather than comply. Apple's UK support page confirms new UK users can no longer enable the feature.
UK users are now on what Apple calls Standard Data Protection for those categories. Apple holds the encryption keys for your photos, notes, backups, voice memos, and iCloud Drive files. A court order could require Apple to hand that data over. That is a different security model from what most UK Apple users believed they had.
iCloud Keychain (saved passwords), Health data, iMessage, and FaceTime remain fully end-to-end encrypted in the UK. Those have not changed.
None of this alters how Apple Intelligence processes your requests. It is background context about how your iCloud data is held in the UK. Since Apple Intelligence can now summarise your emails and read information from your apps, knowing the wider picture of UK iCloud security is a reasonable thing to do. The ICO has published guidance on AI and data protection under UK GDPR, though it has not issued a specific ruling on Apple Intelligence itself.
What Should You Never Ask Apple Intelligence?
The on-device design gives Apple Intelligence a cleaner record than most AI tools for everyday tasks. The common-sense rules still apply, though.
Keep these out of any AI conversation, including Siri:
- Your NHS number or National Insurance number. These are hard to replace if misused, and no AI tool needs them.
- Bank account details, sort codes, or card numbers. No legitimate service will ask for these through a voice assistant or chatbot.
- Passwords or PINs. Not with Siri, not with ChatGPT, not with any digital service.
- Passport or driving licence numbers. Same level of caution as financial details.
- Other people's personal information. If you are drafting something about a friend or family member, leave out their identifying details.
Our guide on what not to share with any AI chatbot has the complete list with the reasoning behind each item. Everything there applies equally to Siri and Apple Intelligence.
A note on voice use: when you speak to Siri, the audio is converted to text on your device for Apple Intelligence requests. That conversion now happens locally. Be mindful of where you are when speaking, though. People nearby may hear questions that are private to you.
How to Control Apple Intelligence on Your Phone
You have more control than you might expect. All of the following settings are available in the main Settings app on your iPhone or iPad:
Turn off Apple Intelligence entirely:
Settings > Apple Intelligence & Siri > toggle off Apple Intelligence.
Keep Apple Intelligence but remove the ChatGPT connection:
Settings > Apple Intelligence & Siri > ChatGPT > toggle off.
See how your requests are being processed:
Settings > Privacy & Security > Apple Intelligence Report.
Control which apps Siri can read:
Settings > Apple Intelligence & Siri > Apps in Siri. You can stop Siri from reading your messages, emails, or other apps individually.
Block Apple Intelligence on a device used by someone you support:
Settings > Screen Time > Content & Privacy Restrictions > Apple Intelligence & Siri. This disables specific features for a device you manage.
Is Apple Intelligence Safe for UK Users?
For everyday tasks, yes. Writing help, email summaries, note organisation, and standard Siri queries all happen on your device. Your data does not leave your phone for those, which is genuinely more private than typing into a web browser or using an AI chatbot online.
The ChatGPT connection introduces a third party, but Apple's negotiated protections take care of the main risks: no IP sharing, no model training on your data without a signed-in account. The per-request consent means nothing is forwarded without your knowing.
The UK iCloud story is the bigger privacy question, though it sits separate from how Apple Intelligence itself processes requests. UK users have less iCloud encryption than users in most other countries, and that context is worth having.
Compared to other AI tools available in the UK, Apple Intelligence sits near the top for consumer privacy. ChatGPT processes everything on OpenAI's servers by default. Claude works similarly. Grok is under active investigation by the UK's Information Commissioner's Office. Meta AI is closely tied to your Facebook and Instagram data. Apple's on-device approach is a genuine privacy advantage, even with the caveats above.
If you prefer not to use Apple Intelligence at all, the off switch is at Settings > Apple Intelligence & Siri. Nothing changes about your iPhone if you leave it disabled.

FAQ
Is Apple Intelligence turned on automatically in the UK?
No. Apple Intelligence has to be enabled manually. It does not activate without a deliberate choice on your part. If you have an iPhone 15 or later with iOS 18.2 or newer, you may have been prompted to turn it on when updating the software, but that prompt requires an active decision. To check whether it is currently on, go to Settings > Apple Intelligence & Siri. If the toggle at the top is grey, it is off.
Which UK iPhones and iPads support Apple Intelligence?
Apple Intelligence works on the iPhone 15, iPhone 15 Plus, iPhone 15 Pro, iPhone 15 Pro Max, and all later models. It requires iOS 18.2 or newer. Older iPhones, including the iPhone 14 range, do not support it regardless of the software version installed. For iPads, any model with an A17 Pro chip or any M-series chip (M1 or later) is compatible, covering iPad Pro models from 2021 onwards.
Does Apple Intelligence listen to me all the time?
No. The upgraded Siri uses on-device detection to listen for the "Hey Siri" wake word. That detection runs locally and does not send audio to Apple. Only once you have activated Siri and given a request does any processing begin. If you would rather not have the always-on wake word active, go to Settings > Siri and switch it off. You can still use Siri by pressing the side button instead.
What is Private Cloud Compute, and is it actually private?
Private Cloud Compute is Apple's server infrastructure for handling requests too complex to run entirely on your phone's chip. Apple states that data sent there is used only to complete your request and is never stored on its servers. Apple employees cannot access it. The company publishes technical documentation and allows independent security researchers to verify these claims. No evidence has emerged of Apple breaching these commitments. That said, it is a corporate promise rather than a legal requirement, which is part of why the on-device principle matters: for most tasks, your data never reaches those servers at all.
Why did Apple remove Advanced Data Protection from the UK?
The UK government issued a legal demand requiring Apple to provide access to encrypted iCloud data covered by Advanced Data Protection. Apple chose to withdraw the feature from UK users rather than create a backdoor into encrypted data. Apple and privacy organisations are challenging the government order in court. While that legal process continues, UK users are without the additional encryption layer that ADP provided for photos, notes, backups, voice memos, and several other iCloud categories. Users in the EU, US, Australia, and most other countries still have access to ADP.
Can I use Apple Intelligence without the ChatGPT connection?
Yes. ChatGPT is one optional component within Apple Intelligence, not the whole thing. Turning off the ChatGPT connection in Settings > Apple Intelligence & Siri > ChatGPT leaves all other Apple Intelligence features active. Writing tools, email summaries, and the core Siri upgrades all continue to work. Siri simply stops offering to pass complex questions on to ChatGPT.
