AllergyEZ

About AllergyEZ

We're parents. There's no company behind AllergyEZ — no office, no investors, no funding, no staff. It's a small family project, built in whatever spare time we have and given away free, because we couldn't think of a good reason to do anything else.

Please read this part first

  • Every translation here is unverified. None has been checked by a qualified medical translator.
  • Have your card read back to you by a fluent native speaker before you rely on it. This is the most important thing we ask of anyone who uses AllergyEZ. Where the stakes are higher — a long stay, a school, a hospital — check it with local health or food-safety officials too.
  • A card never replaces your doctor, the medication they prescribed, or talking to the kitchen yourself.
  • The hidden-ingredient warnings are a starting point, not a complete list of everything in a kitchen.
  • Confirm the local emergency number when you arrive. We show the number for the country you pick, but numbers change and we are not always the first to know.
  • If something reads wrong, please tell us: info@allergyez.com

More on all of this below, and in safety & verification, terms of use and privacy.

Evi

Evi is our daughter, and she is the reason this exists.

Travelling with her taught us how thin the line is between a nice dinner and the worst night of your life — how a word can go missing between what you said and what the kitchen heard, and how little a parent can do about it in a language they don't speak. We built the thing we wished we'd had, and then it seemed unkind to keep it.

We don't publish her allergies or her photograph. She's too young to decide whether she wants that permanently attached to her name, and that decision should be hers.

We're building this as a family business rather than a charity, and we'd rather say so plainly: if it ever makes more than it costs, that goes back into the project and into our family — including into an account for Evi, for when she starts her own life. What we do publish is what we spend, because if you ever support this you should be able to see whether the money reached a translator.

We hope she stays exactly who she is: the most loving, most careful little girl, who asks other children at a party whether they can eat the cake before she takes a slice.

Why we made it

Travelling with a food-allergic child is frightening. You can plan the flights, the hotel and every meal in advance and still end up standing in a restaurant holding a menu you can't read, trying to explain the most important thing you'll say all day to someone who doesn't share a word with you.

That feeling is why this exists. We wanted the thing we didn't have, so we made it, and then it seemed wrong to keep it to ourselves.

Ezzie, the axolotl on this site, wears nine plumes — one for each allergen on the US list, which has grown over the years as more children's reactions were finally taken seriously. The plumes are her crown, not a code: on a card, allergens are always named in words.

What the card does

You enter your child's allergies once. AllergyEZ writes a card in the language of the place you're going, and tries to say more than "no nuts".

For each allergen it lists local ingredients that often hide it — the bonito stock in the miso soup, the shrimp paste in the "vegetarian" Thai curry, the mustard emulsified into a French vinaigrette. That hidden layer is the part a quick phone translation tends to skip past.

Please read those warnings as prompts for a conversation rather than a finished list. No list we write can cover every dish, every regional recipe, or every substitution a kitchen makes on a busy night. Menus change, suppliers change, and a cook may genuinely not know what's in a sauce that arrived in a jar. The card gives you better questions. It can't answer them for you, and it can't tell you a dish is safe.

The card also carries an emergency number, a few urgent phrases sized to stay readable on a screen, a printable version for when the phone is dead, and a QR code so a waiter can open it on their own device. About that number: it's attached to the language, not to your exact location, and one language can span many countries — Spanish covers both 112 in Spain and 911 across much of Latin America; Arabic covers half a dozen different numbers. The card says so where we know it differs, but please confirm the local number when you arrive, and save it in your phone.

By design, nothing about your child comes to us. There are no accounts and no database — the details are encoded into the link itself, in the part of a web address that browsers don't send to servers. That's the whole architecture, and it's why we never receive or hold your child's information.

It also means the card will usually keep working without a signal once the page has loaded. Treat that as a bonus rather than something to depend on: print a copy or save the page before you travel. And the link is yours to look after. Anyone you send it to, anyone holding your unlocked phone, and anyone who picks up a printed card can read what's on it.

What AllergyEZ is not

We're not doctors, allergists, dietitians or translators, and none of us is qualified as any of those things.

AllergyEZ is not medical advice, and using it doesn't create a doctor–patient relationship or any other professional relationship between us and you. It isn't a medical device. It isn't a certification that any food is safe to eat.

It doesn't replace your doctor or allergist. It can't be the reason the adrenaline (epinephrine) auto-injector stays in the hotel room — carry whatever has been prescribed, exactly as you've been told to carry it.

And it doesn't replace the conversation with the kitchen. The card is there to start that conversation and give it vocabulary, never to end it. Hand it over, then talk it through, then watch what arrives at the table. If you're not sure about a dish, don't risk it. If a reaction starts, call 911 in the US and Canada, or the local emergency number where you are.

The part we most need you to read

Every translation in AllergyEZ is unverified. None has been reviewed by a qualified medical translator. Each language pack is flagged unverified in our own code, and every card prints that warning in the local language and in English, because we'd rather you trusted this less and checked it more.

So please have your card read back to you by a fluent native speaker before you rely on it. Do it before you travel if you possibly can, when there's time and nobody is hungry — a friend, a colleague, your host, hotel reception, a local pharmacist. Read the card through with them and make sure it says what you think it says. Where the stakes are higher — an unfamiliar cuisine, a long stay, a school, a hospital — check it with local health or food-safety officials as well.

Machine translation can be wrong. It can be subtly wrong, which is worse: a sentence that reads fluently and means something slightly different, or an ingredient name that's technically correct and locally unheard of. It can be wrong in ways that look completely right to us and to you.

It can also go out of date. We correct language packs when we can, so a printed card or an old link is a snapshot of the day it was made, not the current version. Please make a fresh card before each trip.

Please tell us when we're wrong

If you speak one of these languages and something reads badly, reads oddly, or is simply wrong, we want to know — even if you're not certain, even if it's one word. Write to info@allergyez.com.

Corrections from native speakers are the only way this gets better, and every one we receive protects a family we'll never meet. We read what we can, and we're not defensive about it. We can't promise we'll see every message, that we'll reply, or that anything gets fixed by a date — and please don't use that address for anything urgent. In an emergency, call the local emergency number.

The limits, plainly

We'd rather say this in our own words than bury it. The full version is in our terms of use.

AllergyEZ is free and provided as is, with no warranties of any kind, express or implied — including any warranty of accuracy or of fitness for a particular purpose.

We can't promise:

  • that a translation is accurate, complete or current;
  • that the hidden-ingredient warnings cover every risk in a given kitchen;
  • that an emergency number is right for the exact place you're standing;
  • that a kitchen will read the card, understand it, believe it or act on it;
  • that the app will be working, or reachable, at the moment you need it.

To the fullest extent the law allows, we aren't liable for any loss, injury or harm arising from using AllergyEZ, from relying on anything it says, or from a card being shared onward to anyone else. By using it, you accept that risk yourself, and you take responsibility for checking anything your child's safety depends on. Nothing here is intended to limit any liability that can't lawfully be limited.

That's doing legal work, but it's also just true. We're parents with a text editor and good intentions, and good intentions don't make a translation correct.

Please get the translation checked. Please carry the medication. Please talk to the kitchen anyway.

What does and doesn't happen to your data is on our privacy page.

We built this from a place of love. We hope it helps. We hope you never need the emergency screen.
