Privacy policy for «Misión: aprender jugando»
Last updated: 5 November 2026
«Misión: aprender jugando» is a maths game for primary school children aged 6 to 12,
developed by cereus.dev. This policy explains what data the Android app
(package dev.cereus.operacionaprender, distributed on Google Play) and its
Windows version handle.
Summary
The game does not collect, send or share any personal data. It needs no internet connection and requests no permissions, and it has no advertising, purchases, chat, user registration or third-party services.
What is stored and where
To make the game work, only the following is stored, on the device itself:
- The characters created in the game's editor: a name or nickname and their look (hairstyle, clothes, colours...).
- The ranking for each school year: the character's name and their points.
- The settings: school year, operations, difficulty, sound and music.
On Android, this data lives in the app's internal storage, which the system protects so other apps cannot read it, and it is not included in cloud backups. On Windows it is stored in text files next to the game. It never reaches cereus.dev or any third party.
We recommend entering only a first name or a nickname, without surnames.
What the game does not do
It does not use the camera, microphone, location, contacts or the device's files. It does not read device or advertising identifiers, includes no analytics or tracking tools, and does not sell or share any data.
Retention and deletion
The data stays on the device until it is deleted:
- From the game: in PERSONAJES (characters) each character can be edited or deleted, and in RANKING the bin clears the ranking for a school year.
- From Android settings: in the app info, by clearing its storage.
- By uninstalling the app, which removes all its data.
As cereus.dev receives no data, it holds no information about the game's users that could be accessed, corrected or deleted.
Children
The game is designed to be used by children, at home or in class, under the supervision of their families or teachers. That is why it has no ads or purchases, collects no data from children and does not allow communicating with other people.
Links outside the game
The game's only link is the PRIVACIDAD (privacy) button in the information panel, which opens this page in the device's browser. When visiting this website, its own privacy and cookie policies apply.
Google Play
When you download the app from Google Play, Google processes the download data under its own privacy policy: https://policies.google.com/privacy
Changes to this policy
If a future version of the game changes how data is handled, for example by adding online features, this policy will be updated before that version is released and, where required, families' consent will be requested. The date above shows the latest update.
