Momu Kids Privacy Policy

Last updated: October 5, 2026

Momu Kids is an app for children to draw, color, trace, practice letters and numbers, and play with shapes and colors. This policy says plainly what leaves the device and what stays on it. It is written to be read by a parent, not by a lawyer.

The account belongs to the grown-up

To use Momu Kids, the grown-up creates an account at the end of the welcome screens, with Apple, with Google or with an email. The account keeps your family's credits, subscription, packs and drawings, so they are not lost if you delete the app or change iPad. The child never sees a sign-up screen and we do not ask children for sign-in details.

From the account we receive your email, and with Apple you can hide the real one: Apple gives us a forwarding address and never shows us yours.

There is one optional use of that email: telling you about Momu news and offers. It ships turned off. We only write to you about that if you turn the switch on, and you can turn it off whenever you want from the parent area or from the link at the bottom of every email. Your account and your purchases do not depend on that switch.

What is kept in your account

Since version 1.8, drawings belong to the account, not to the iPad. So if you delete the app or sign in with your account on another iPad, they are there.

• Your children's profiles: first name, age, the emoji they picked and the days they colored (for their streak).
• The drawings, the coloring painted on top of them, and the stories, with their sentences and their voice. Pages made from a photo are kept already turned into lines; the photo itself is never kept.

They are stored in Google Firebase, in a folder of your account that only your account can open. They are not used for anything else: they do not train artificial intelligence, they are not shared, and nobody at Momu looks at them. If you delete a drawing on one iPad, it is deleted from the account too.

What stays on the device

• What the child traces, handwrites or solves in math. Strokes are checked on the iPad itself, including recognizing the numbers they write: they are not sent to any server.
• Their stars.

The parent area also includes a way to back everything up into a single file you keep wherever you want.

What leaves the device

• What the child asked for. The subject text, for example "a dinosaur at the beach", is sent to our server and from there to OpenAI to generate the drawing, both for coloring and for tracing.
• The first name and the age. When creating a story, because the child is the main character, and in math story problems ("Sofia has 4 balloons…"). For those problems we also send a subject the child already asked to draw, so the story is about something they like. The numbers and the answer are computed by the app, not by the AI.
• Photos you choose. Only if you use the feature that turns a photo into a coloring page. The photo is sent, reviewed, converted into line art and returned. We do not store it.
• Microphone audio. This is handled by iOS, not by us: Apple turns it into text. We never receive or store a child's audio. Words the child dictates to practice writing stay on the iPad.
• Your email, to identify your account, to give back what you purchased if you change device and, only if you turned it on, to tell you about news.
• Your credit balance and its history. How many credits you have, and a record of purchases, renewals and spending, so any billing question can be resolved.
• Activity numbers, once a day. How many drawings, stories, colored pages, tracings, letter sheets, math rounds and shape games were done. Integers and nothing else: never the child's name, never what they asked for, never what time they played. They add up on the iPad and are sent together once a day, precisely so nobody's routine can be reconstructed.

The shared cache

Children ask for very similar things. When someone asks for "a unicorn", the resulting drawing is stored on our server under a key that is a mathematical digest of the subject, so the next child who asks for the same thing gets it instantly and at no cost. That cache holds only the line drawing. Photos and stories with names never go into it.

What we do not do

• There is no advertising. No banners, no videos, nothing.
• There is no third-party measurement or advertising tool inside the app. We count the activity numbers ourselves, on our own server.
• We do not sell data. The only thing we share outside, to measure our ads, is what is explained in "How we measure our ads".
• There are no links to social networks or outside sites inside the child's part of the app.

How we measure our ads

We advertise Momu on Instagram and Facebook. To know whether those ads work, our server tells Meta when someone installs Momu, starts the free trial or pays. The notice carries the type of event, the price and currency of the purchase, the app and system versions, the device model (for example "iPad8,1"), the language and the time zone.

Each notice stands alone: it does not carry your account, your email, your name or any identifier that would let Meta know which family it comes from, and it never carries anything from the child (name, drawings, stories, photos or voice).

The app also uses SKAdNetwork, an Apple feature that tells Meta, anonymously and in aggregate, how many installs came from each ad. Momu does not ask for Apple's tracking permission and does not use the device's advertising identifier.

Who we work with

• Google Firebase. Accounts, database, functions, and storage for the cache and for your account's drawings.
• OpenAI. Generates the drawings, writes the stories and the story problems, and records the voice.
• Apple. Sign in with Apple, turns speech into text and processes payments. We never see your card details.
• Google. Only if you choose to sign in with Google.
• Meta (Instagram and Facebook). Measuring our ads, as explained above.

Children

This app is made for children. We do not ask them for personal data: the parent types the first name and the age when creating the profile, and that is the only thing used to personalize the drawings, the stories and the problems. We collect no location, no contacts and no advertising identifiers. The parent area sits behind a math problem precisely so that a small child does not get into it.

How to erase everything

In the app: parent area, Erase everything. That deletes the profiles, the drawings and the stories from the device, and asks our server to delete your account, the drawings, stories and profiles kept in it, your balance, its history and your household's activity numbers.

You can also write to us at hola@momukids.com and we will do it for you.

How long we keep things

• Your account, your balance and its history: for as long as you keep the account.
• The drawings, stories and profiles in your account: for as long as you keep the account, or until you delete them.
• The receipt of each Apple charge (a transaction number, no card details): kept even if you delete the account, because it is what prevents the same purchase from being credited twice.
• The shared cache drawings: indefinitely, because they contain nothing personal.
• Everything else lives on your device and you control it.

Changes

If this policy changes, we update the date above. If the change is substantial, we say so inside the app.
