KinCode

KinCode is a simple way to recover the few telephone numbers that matter when the phone that normally holds them is unavailable.

Almost nobody memorises a telephone number any more. There is no need to — the numbers that matter live in a phone, behind a lock screen, and they are always to hand. Until they aren't. It is worth asking how many of the numbers you depend on you could write down right now, unaided.

A phone runs flat on the way home. It is left on a bus, dropped in a puddle, or taken away. Someone is standing somewhere unfamiliar with a borrowed handset in their hand, and cannot recall a single number to ring.

KinCode is a small answer to that. You store a handful of important first names and telephone numbers in advance — for yourself, or, with their agreement, for someone you support. They can then be retrieved from any internet-connected device using a memorable phrase and a separate six-digit PIN. Whoever is retrieving them needs no app, no login, and no account of their own.

KinCode is a contact-recovery utility. It is not an emergency service, a care alarm, or a medical alert device, and it does not replace 999, 112, or any other emergency arrangement. In an emergency, always contact the emergency services first.

KinCode is currently in development. If you would like to know when it opens, we would be glad to let you know.

Who it's for

Anyone who carries a phone, which is very nearly everyone. The situation KinCode covers is not a childhood one, and it is not an old-age one either.

• You, when your phone is stolen, drowned, flat, or left in the back of a taxi
• A new handset that has not finished pulling your contacts across yet
• A child with no phone of their own, or one that has died halfway through the afternoon
• An older relative who still goes out alone and has left the phone at home on charge
• Anyone whose recall goes when they are upset, hurried, or unwell — which is most people

Losing your bearings is not a failure of character and it is not confined to any age. KinCode makes no judgement about why the numbers are not to hand.

Why this matters

The contacts anyone needs in a difficult moment are rarely the ones they can reach. A locked phone is a locked address book, and the people most able to help are the people whose numbers only exist inside it.

• A flat battery makes every stored number unreachable at once
• A lost or stolen phone takes the contact list with it
• A borrowed handset holds someone else's contacts, not yours
• Written notes are lost, laundered, or simply left at home

The traditional answer — a number written on the back of a hand, tucked into a school bag, or saved in the other phone — works right up until the moment it doesn't. KinCode keeps the same short list somewhere it cannot be mislaid, reachable from whatever device happens to be available.

How it works

Setting up a recovery profile takes a few minutes, and only the person setting it up ever needs an account — which can be you, for your own list.

• Add up to five contacts — a first name and a telephone number for each
• Put them in the order they should be tried
• KinCode generates a memorable phrase; you choose nothing and invent nothing
• A separate six-digit PIN is issued alongside it
• Learn the phrase and PIN yourself, or share them with the person the list is for and practise together

To retrieve the list, you visit KinCode on any device with an internet connection, enter the phrase and the PIN, and see the first names and numbers that were saved. One tap hides them again.

The phrase is deliberately made of ordinary, unthreatening words, and the word list is built so that no two words in it are a single slip apart. A phrase misheard over a bad telephone line cannot quietly turn into somebody else's valid phrase.

When practising isn't realistic

Rehearsing a four-word phrase suits some people and not others. KinCode can supply a printed card carrying the phrase, sized for a wallet or a purse. It is a paid extra, charged on top of your subscription, and it is entirely optional — a card you write out yourself works exactly as well.

The card carries the phrase, the KinCode web address and brief instructions. It never carries the PIN, contact names or telephone numbers. The PIN is kept separately — memorised if that is realistic, or noted somewhere apart from the card. Split that way, a lost wallet does not hand over the list.

Where neither the phrase nor the PIN can be held reliably, KinCode is the wrong tool. We would rather say so than sell you something that will not work on the day.

What this looks like

A wallet taken in another country

A man on a work trip has his phone and wallet lifted together on the walk back to the hotel. He borrows a laptop at the front desk and gets as far as the hotel wi-fi before realising he cannot ring anyone. His partner's number has lived in a contacts list for eleven years.

He opens KinCode, enters his own phrase and PIN, and there they are.

A phone that died in a coat pocket

A thirteen-year-old is meant to be collected from a friend's house at six. Plans change, the friend's family leaves earlier than expected, and her phone — already low that morning — has died in her coat pocket.

She asks to borrow the friend's mother's phone. She does not know her own mother's mobile number; it has lived in her contacts since she got her first handset.

She opens KinCode in the browser, types the four-word phrase she and her mother rehearsed, enters her PIN, and sees three names and numbers: Mum, Dad, Nan. She rings the first one, and hides the list before handing the phone back.

No account was created. Nobody asked her name, her age, or where she was.

A walk that took a wrong turn

An older man sets out on his usual route and ends up on a road he does not recognise. His phone is at home on charge. He steps into a shop and asks whether he might borrow theirs.

He takes the card from his wallet, types the phrase, enters the PIN he has known for months, and rings his daughter.

Nobody had to ring a helpline on his behalf, and nobody had to decide whether he should still be going out on his own.

What KinCode never asks for

The strongest privacy protection is the information that is never collected in the first place. Whoever retrieves the contacts provides a phrase and a PIN, and nothing else.

• No account for whoever is retrieving contacts — there is nothing for them to sign up for
• No name, date of birth, address, school or workplace, or photograph
• No location tracking and no behavioural profiling
• No advertising, ever

There is one deliberate omission that deserves stating plainly: whoever sets up a profile cannot see when, or whether, it has been used. It would be a straightforward feature to build and an easy one to sell, and it would turn a safety tool into a surveillance tool aimed at the very person it exists to protect. That applies at least as strongly to an adult: someone who needs help reaching their family has not given up their right to a private afternoon. KinCode will not do it.

Built to be used under pressure

The retrieval page is designed for someone who may be upset, hurried, outdoors in poor light, using one hand or an unsteady one, on a device they have never held before. Accessibility and usability are the same requirement here, so a failure on that page is treated as a fault in the product rather than a refinement to be added later.

• Designed and tested against WCAG 2.2 AA, with automated accessibility checks included in every build.
• Type large enough to read at arm's length, and no time limit on entering the phrase
• Generous touch targets, clear focus, and plain UK English
• Full keyboard operation and screen-reader support
• Works in current mainstream browsers, with nothing to install
• Forgiving input: capitals, spacing, and leading zeroes in the PIN all behave sensibly

How your contacts are protected

Contact details are encrypted before they are stored, using authenticated AES-256 encryption. The memorable phrase is never held in a readable form, and the PIN is stored using Argon2id — a deliberately slow algorithm chosen to make bulk guessing expensive.

A six-digit PIN is short by design, because a long passphrase is no use to anyone who is upset, hurried, or struggling to think straight. That trade-off is covered by strictly limiting how often a phrase and PIN may be tried, so that repeated guessing is stopped long before it could succeed.

Encrypted contact records are stored in Google Cloud’s London region. Some account, authentication and payment information is processed outside the UK by the service providers KinCode relies upon; these arrangements are explained fully in the privacy notice.

Being straight with you

Some things about a service like this should be said openly rather than buried.

• It is not an emergency service. KinCode does not guarantee availability and is not a substitute for 999 or 112
• It is not a care alarm. KinCode does not detect falls, does not raise an alert, and nobody is monitoring it. It waits to be asked
• It is not end-to-end encrypted. KinCode holds the encryption keys, which is what makes it possible to stop guessing attacks — but it means we are technically capable of reading stored contacts
• It needs an internet connection. A device with no signal cannot reach KinCode
• It leaves a trace on the device. After a call, the number stays in that phone's call history, and KinCode cannot remove it
• It is a paid service. KinCode is a subscription, and the printed card is charged on top of it
• A card can be lost. If you use one it carries the phrase only, which is precisely why the PIN must be kept somewhere else

None of these are reasons not to use KinCode. They are the things you should know before you rely on it.

A sensible precaution

KinCode is not insurance against everything that can go wrong. It covers one narrow, common, genuinely stressful situation: needing to reach a trusted person without the phone that normally holds their number.

A few minutes of setup, a phrase worth learning properly, and a short list of people who will always pick up — for whoever in your life might need it, yourself included.
