The Kitchen App Knows Your Wi-Fi: A Worktop Privacy Tidy-Up

There is a moment, usually about ten minutes after unboxing a new connected kitchen gadget, when the app asks for your birthday. Then your location. Then permission to send you offers. You only wanted a decent cup of coffee or a crispier chip, and suddenly you are managing a user profile for a device that sits next to the toaster.

That is not a reason to abandon the gadget. It is a reason to treat the setup screens with the same mild suspicion you would give a doorstep seller. A few small choices now can keep the useful bits — remote start, recipe prompts, firmware updates — while cutting back the data trail you never signed up for.

Why a coffee machine wants a profile

Most connected kitchen appliances are not really selling you a machine any more. They are selling an account. The app is where recipes, guided cooking, diagnostics and warranty registration live. It is also where the manufacturer can learn how often you use the device, which programmes you choose and whether you open the promotional notifications.

Some of that is legitimate. Usage data helps a firm spot a faulty batch or improve a recipe. A device identifier helps support staff find your model. But a birthday, a phone number and precise location are rarely needed to grill a piece of salmon. When an app asks for them, it is often building a marketing profile rather than improving the cooking.

Under UK data protection rules, companies should only collect what they need for a stated purpose. The Information Commissioner's Office has been clear that consent must be freely given, specific and easy to withdraw. In practice, that means the toggles matter. The pre-ticked box for 'news and offers' is not a legal requirement for your air fryer to work.

What is actually being collected

The exact list varies by brand, but common requests include:

• Account details: name, email address, password and sometimes date of birth.
• Device information: model, serial number, firmware version and app version.
• Network details: your Wi-Fi network name and signal strength.
• Usage data: which programmes you select and how long the appliance runs.
• Location: often optional, sometimes requested for delivery, support or regional recipes.
• Contacts or calendar access: rare in kitchen apps, but not unheard of when a recipe planner wants to add meals to your diary.
• Voice recordings: if the appliance has a voice assistant or you use one nearby.

None of this is automatically sinister. The problem is accumulation. A kettle that knows your postcode, a fridge that knows your shopping habits and a coffee machine that knows your morning routine add up to a fairly detailed picture of a household. That picture becomes more valuable when it is combined with data from other apps and loyalty schemes.

The five-minute worktop audit

You do not need a weekend. Set a timer and work through these checks on the phone you use to control the appliance.

1. Open the app permissions screen

On iPhone, go to Settings, scroll to the app and review what it can access. On Android, open Settings, then Apps, then the app's Permissions. Turn off anything that is not essential: location, contacts, microphone, photos and Bluetooth are the usual suspects. A recipe app does not need your contact list.

2. Find the marketing toggles

They are often buried under Account, Privacy, Notifications or Communication Preferences. Switch off email marketing, push offers and 'partner offers' if you do not want them. This does not usually affect warranty or safety notices, but check the wording. Some firms bundle 'important product updates' with marketing; those updates are worth keeping.

3. Review location access

If the app offers regional recipes or a service locator, 'while using the app' is usually enough. 'Always' is rarely necessary for a kitchen appliance. If the app will not work without precise location, ask yourself whether you actually need that feature.

4. Put it on the guest network

Many home routers offer a separate guest Wi-Fi network. Putting smart kitchen gadgets there keeps them away from laptops and phones that hold work files and personal email. It also makes it easier to switch them off if a device stops receiving security updates. Check your router manual or app for the guest network setting.

5. Decide about remote features

Remote start and voice control are convenient. They also mean the appliance can be operated from outside the kitchen. If you live alone and rarely use remote start, turn it off. If you do use it, make sure the app account has a strong, unique password and two-factor authentication where available.

6. Delete old accounts and data

If you have replaced a gadget, log in to the old app and use the account deletion or data request option. Under UK GDPR you can ask for a copy of your data or its erasure. It is not always instant, but it is worth doing before the old device sits in a cupboard for another three years.

7. Check for firmware updates

Security fixes for connected devices often arrive as firmware updates. Open the appliance settings in the app and look for updates, or check the manufacturer's support page. Since the Product Security and Telecommunications Infrastructure Act rules came into force in 2024, manufacturers have had stronger obligations to tell you about support periods and security updates. Use that information: if a device is no longer supported, treat it as a kitchen appliance rather than a connected one.

When to say no to the app

Some connected features are genuinely useful. A coffee machine that remembers your preferred strength, an oven that alerts you when the roast is ready, or an air fryer that pushes a firmware fix are all reasonable. But you can often skip the account entirely and use the physical controls.

Before you hand over an email address, ask what happens if you decline. If the answer is 'the basic functions still work', decline the marketing and keep the app for updates only. If the device becomes a brick without an account, that is worth knowing before you buy — and worth mentioning in a review.

A quick note for small firms

If your office kitchen has a connected coffee machine or fridge, treat it like any other device on the network. Do not use a shared personal account with a weak password. Give it its own guest network, keep the admin credentials in a password manager and decide who is allowed to change settings. Staff birthdays and contact details should not end up in a kitchen appliance app by accident.

The worktop is not a high-security zone. But it is part of your home network now, and a five-minute tidy-up is a lot easier than untangling an account you forgot you had. Keep the features you use. Drop the requests that make no sense. Your coffee will taste the same either way.
