Your menu is public Everything you publish — dish names, descriptions, prices, and photos — is visible to anyone who scans your QR code. Keep prices and allergen information accurate: your guests may rely on them.

How to use La Carta

Create your account
  1. Open La Carta and choose Sign up
  2. Enter your name, your email address, and a password
  3. We email you a three-digit verification code. Type it into the App to confirm the address is yours
  4. You're in. Your session is stored securely in the device Keychain, so you won't have to sign in again on this device

If the code doesn't arrive within a minute, check your spam folder and confirm the address you typed is correct.

Set up your restaurant and build the menu
  1. Create your restaurant and give it its name
  2. Add categories first — Starters, Main courses, Drinks, Desserts, whatever fits your place
  3. Add dishes inside each category, with a name, a description, and a price
  4. Optionally add a photo to a dish (see the next section)
  5. Changes are saved to your menu right away — the next guest who scans sees the updated version

A short, honest description sells better than a long one. Write what the dish actually is.

Add a photo to a dish
  1. Open the dish you want to illustrate
  2. Tap to add a photo — the standard iOS photo picker opens
  3. Choose one image from your library. The App receives only that image; it never gets access to the rest of your photos, which is why it doesn't ask for photo library permission
  4. The photo uploads to our server and appears on your public menu

Only upload photos you have the right to use. Photos you took yourself are always safe; images pulled from the internet or from another restaurant are not.

Put the QR code on your tables
  1. Open your restaurant's QR code in the App
  2. Print it, or have it printed on a table tent, a sticker, or the corner of a physical menu
  3. A guest points their phone camera at it — the menu opens in their browser at menu.ingenieria.dev
  4. They install nothing and sign up for nothing

Print it large enough to scan comfortably from a seated position, and keep it clean — a scratched or greasy code scans badly.

Receive and read orders
  1. Keep the App open on the orders screen in the kitchen or at the counter, on an iPhone or iPad
  2. When a table sends an order it appears as a ticket, showing the dishes, the quantities, and the table it came from
  3. If you allowed notifications, you also get an alert the moment it arrives

Notifications depend on iOS and on your connection, so treat them as a convenience, not a guarantee. Glance at the orders screen too.

Manage more than one restaurant
  1. Add each venue as its own restaurant inside the same account
  2. Each one keeps its own categories, dishes, prices, and QR code
  3. Switch between them from the App to edit the right menu or watch the right orders screen
Turn notifications on or off
  1. Open the iOS Settings app
  2. Scroll to La Carta
  3. Tap Notifications
  4. Turn Allow Notifications on or off

With notifications off, the App keeps working normally — you just watch the orders screen yourself.

Change your password

Change it from your account settings in the App. If you've forgotten it, use the password reset option on the sign-in screen: we email a code to the address on your account so you can set a new one.

We store your password only as an Argon2id hash, so nobody here can read it or tell you what it was — a forgotten password is always reset, never recovered.

Delete your account and everything in it
  1. Open your account settings in the App
  2. Choose to delete your account and confirm

You can also request deletion by emailing [email protected] from the address on the account.

Deletion is permanent. It removes your name, your email address, your password hash, your restaurants, your dishes, your uploaded photos, and the associated orders from our server. Your QR codes stop working. This cannot be undone, so export or write down anything you want to keep first.

Frequently asked questions

Do I have to pay anything?

No. La Carta is free, with no In-App Purchases, no subscription, no ads, and no paywall. We also take no commission on the orders your guests place or on anything you sell. If you enjoy the App and want to support the work, email [email protected] — that's enough.

Do my guests have to install the app?

No, and that's the point. The App is for you and your staff. Your guests scan the QR code on the table and your menu opens in their phone's normal browser. They install nothing, create no account, and give up no personal data to order a coffee.

Do you store my data on any server?

Yes — unlike a purely offline app, La Carta needs a server, because your menu has to be reachable by a guest's phone. We store your account (name, email, and your password as an Argon2id hash, never in plain text) and the menu content you publish, on our own server at menu.ingenieria.dev. It runs a PostgreSQL database on infrastructure we rent from Digital Ocean in San Francisco, and all traffic travels over HTTPS. Photos of dishes are stored as files on that same server, not on a third-party image host. Full detail is in our Privacy Policy.

What do you know about my guests?

Almost nothing, on purpose. We never ask a diner for a name, an email address, or a phone number, and we have none on file. What the server keeps is the order itself (which dishes, which table), any rating or comment they chose to leave, and a random table-session identifier that expires after three hours — it exists only so their cart survives while they read the menu, and it identifies nobody.

Do you sell my data, or show ads?

No to both, and we never will. There are no ads, no advertising networks, no third-party analytics, no tracking SDKs, and no profiling. The only outside parties that ever touch any data are our hosting provider and the service that delivers your verification email — both strictly so the App can work. The App never asks for App Tracking Transparency permission, because it tracks nothing.

Who sends the verification email?

Resend, an email delivery service. To deliver the message they receive your email address and the code itself — nothing else. Not your password, not your menu, not your orders.

Does La Carta take a commission on my sales?

No. We never sit between you and your guest's money. The App transmits an order from a table to your kitchen; the payment happens at your restaurant, by whatever means you already use. We don't process payments and we don't handle money at all.

Why does the App need an account when other apps don't?

Because your menu has to live somewhere your guests' phones can reach. An app that keeps everything on your device could never serve a web page to a stranger at table four. The account is what ties your menu, your QR codes, and your orders together — and it's also what lets you sign in from the phone in your pocket and the iPad in the kitchen and see the same thing.

Can I use it on an iPad in the kitchen?

Yes. La Carta runs on both iPhone and iPad, and on iPad it supports landscape as well as portrait, which is usually how a tablet propped up on the counter is used. Sign in on each device with the same account and both will show your menu and your orders.

Does it work without an internet connection?

No. La Carta needs a connection, both for you to edit your menu and for your guests to load it when they scan. If your connection drops, guests won't be able to open the menu until it's back. This is the trade-off for a menu that lives on your guests' phones instead of on paper.

I changed a price. When do guests see it?

On their next scan or refresh. There's no re-publishing step and nothing to reprint — you edit the price once in the App and the menu served to the table is the updated one.

Why didn't I get a notification for an order?

Check that notifications are enabled in Settings → La Carta → Notifications, that the device isn't in Focus or Do Not Disturb mode, and that it has a working connection. Notifications travel through Apple's push service, so delivery can't be guaranteed — always keep an eye on the orders screen as well.

Can a guest leave a bad review of a dish?

Yes. Guests can rate a dish and leave a comment after ordering it, and we don't edit those opinions in your favor. That's the value of it: you learn which plate is quietly disappointing people before a public review site tells the world. If a comment is unlawful, abusive, or obviously fraudulent, email us and we'll review it.

Which iPhones and iPads are supported?

Any iPhone or iPad running iOS 26 or later. Your guests need no particular phone — the menu opens in any modern mobile browser.

How do I report a bug?

Email [email protected] and include:

Please don't include your password in the email — we never need it.

Can I suggest a new feature?

Yes — we love hearing ideas, especially from people actually running a kitchen. Email [email protected] with your proposal. We review every suggestion.
