Privacy policy · updated September 2026
Math Master Kids keeps everything on the phone or tablet it is installed on. It has no accounts, no sign-in, and no adverts. It asks for no access to your camera, files, contacts or location — not even permission to use the internet. Nothing a child types into it is ever sent anywhere.
So that the app can greet a child by name and remember where they got to, it saves: their first name; which class they are in; the character and pet they picked; and their scores, badges, streak, coins and which questions they have answered.
The setup screen also offers two optional boxes — school name and teacher name. They can be left empty, and the app works exactly the same if they are.
That is the whole list. The app never asks for a surname, an address, a date of birth, a phone number, an email address, a photograph, or a location.
All of it is written to the app's own private storage on the device, which no other app can read.
It is not sent to us. It is not sent to anybody else. There is no server behind this app to send it to — the release build makes no network connections, and does not request the permission that would let it.
Android's automatic cloud backup is switched off for this app on purpose, so a child's name and school are not copied to anyone's Google Drive either.
The app shows no adverts of any kind. It contains no advertising, analytics, attribution or crash-reporting libraries. Nothing profiles the child, and nothing follows them between apps.
There is nothing to buy inside the app, and no way to spend real money. The coins a child earns are part of the game and have no cash value.
There is no chat, no messaging, no comments and no leaderboard, and no way for anyone to reach a child through this app.
The one thing that can leave it is a worksheet: the Download Centre builds a PDF that a grown-up can print, save or send on. The sheet holds maths questions and a blank name line — never the child's name, school or scores.
The illustrations were produced with an image-generation tool and ship inside the app, which is why it works with no internet. The questions follow the NCERT 2025-26 mathematics syllabus for Class 5 and Class 6 and were written for this app.
Open Profile, then "Delete my details". That erases the name, class, school, teacher, character and every score, and returns the app to how it was on the first run.
Uninstalling the app also removes everything it stored. Because none of it was ever sent anywhere, there is nothing left elsewhere to ask us to delete.
This app is made for children and is designed so that a parent has nothing to police: no spending, no strangers, no adverts, and no data leaving the device. If you would like the app to forget your child entirely, the step above does it in two taps.
If the app ever starts doing something this page does not describe, this page will be updated first, and the date at the top will change with it.
