People with severe allergies
When a reaction makes it hard to speak, the one fact that changes treatment — penicillin, peanuts, latex — is already on the screen, in signal red.

Who it's for
Made for the moment you can't explain yourself
If a stranger ever has to make a fast decision about your body, these are the details they wish they had.
Anyone managing a chronic condition
Diabetes, epilepsy, a heart condition, blood thinners — context a responder would otherwise have to guess at, ready before they ask.
Parents and caregivers
Carry a profile for a child or a parent you look after. Hand the link to a babysitter, a school, or a sibling in seconds.
Real moments
Built for ordinary days that turn urgent
A live profile
See exactly what a responder sees
No dashboards, no clutter. The most time-critical fields sit up top in signal red; everything else is one glance away. Take a look at a complete example profile, laid out just like the page first responders open.

How it works
Three steps, then forget about it
The whole point is that you set it once and it's there on the worst day, working without you.
01Fill in what matters
Allergies, medications, conditions, blood type, and the people who should be called. Skip anything you don't have — only a name is required.
02Get two links
A public link to share or print, and a private link only you use to make edits later. No password to remember, no account to create.
03Keep it close
Save the public link to your lock screen, a wallet card, or a fridge magnet. Anyone can read it in a tap — no app, no login.
Why LIFEKEY
Designed around the half-second a responder can spare
Every decision in the product answers one question: does this help a stranger act correctly, faster?
- 01
Critical facts come first
Allergies sit at the top in signal red — the one color reserved for the field that changes treatment fastest. Nobody has to hunt.
- 02
No login stands between you and help
A responder opens a plain web link and reads. No app install, no account, no QR-code scavenger hunt during the worst minute of the day.
- 03
Two links, two jobs
A short public link to share and print, and a long secret edit link only you hold. Share one freely; guard the other.
- 04
Private by design
Profiles are kept out of search engines, never cached, and stripped of referrer data so your edit link can't leak through a browser.
- 05
Always the current version
Update a medication or a contact from your private link and the public page reflects it immediately. The fridge magnet never goes stale.
- 06
Free, and it stays free to read
Creating a profile costs nothing, and reading one will never sit behind a paywall. Emergency information shouldn't have a checkout.
The whole security model
Two links. One you share, one you never do.
Public
lifekey.app/p/k7m2qx
Short and safe to hand out. Print it, stick it on the fridge, save it to a lock screen. It only ever shows, never edits.
Private
lifekey.app/edit/••••••••••••
A long, unguessable key that is the only way to change your profile. We keep it out of search results, caches, and referrer headers so it can't slip out of your browser.
There are no accounts and no passwords to breach. Access is the link and nothing else — which is exactly why the edit link is worth guarding.
Questions
The things people ask first
Do I need an account or an app?
No. You fill in a form, and you get two links back. Reading a profile is just opening a web page — there's nothing to download and nothing to sign into.
Who can see my medical information?
Anyone with your public link can read the profile — that's the point, so a responder can. We keep those pages out of search engines and browser caches, so they aren't discoverable; they're only reachable by someone you've shared the link with.
What if I lose my private edit link?
The edit link is the only way to change a profile, so save it somewhere safe — a password manager is ideal. If it's gone, you can always create a fresh profile and share the new public link.
Can someone change my profile?
Only with the private edit link. The public link is strictly read-only, so sharing it can never let anyone alter what it says.
Is it really free?
Creating a profile is free, and reading one always will be. Emergency information shouldn't depend on a subscription being paid up.
How do responders know to look for it?
Most people keep the public link on a phone lock screen, a printed wallet card, or a medical bracelet. It's the same habit as an ICE contact — somewhere a responder already knows to check.
Set it up once.
Be ready every day after.
It takes about three minutes now, and it works on the day you can't do anything at all.
