About PlumoBOX
A thoughtful tool, designed for children.
PlumoBOX brings together simple, free, ad-free educational mini-apps to support students from ages 5–13 at school and at home. No accounts, no cookies, no ads: open an activity, learn, move on.
The team
PlumoBOX is designed and maintained by a game designer and developer of immersive educational software, parent first. The idea is simple: offer schools activities that are both rigorous and joyful, that truly respect all children — every single one.
Accessibility at the core
PlumoBOX is designed from the first line of code to be usable by all students, including those with particular needs.
For students with dyslexia and dyscalculia
Sans-serif fonts, clearly differentiated letters (b, d, p, q), left-aligned text, generous line spacing. Instructions are short, without double negatives, without capitals to remain readable for young learners.
For autistic students
Predictable interface, elements always in the same place. The system preference 'reduced motion' is respected: no surprise animations, nothing flashes, no unexpected popups.
For deaf and hard of hearing students
No mini-app requires hearing or speaking to function. Sound is always supplementary, never the main channel, and is muted by default.
Keyboard navigation and contrast
Everything is reachable by keyboard, with clear visible focus. Instructions aim for AAA contrast in both light and dark modes.
Works everywhere
PlumoBOX works identically on all devices, with no installation needed. A single interface, designed for school first.
Projector
Ideal for group sessions: project a mini-app, ask the class, manipulate in real time. Elements are large and readable from the back of the room.
Interactive whiteboard
Activities are fully touch-enabled. A student comes to the board, manipulates, then passes it on. Targets are large, designed for fingers.
Tablet
Perfect for independent work or small groups. Each student progresses at their own pace, with immediate visual feedback for every action.
Computer, smartphone
Nothing to install: everything runs through the browser. The same activities work at home, on a family computer or a parent's phone.
Our promises
Zero cookies, zero trackers
No pixels, no Google Analytics, no embedded social networks. No consent banner — because there's nothing to consent to.
Zero accounts, zero signup
No email, no password, no profile. Students open the site and start learning, period.
Zero ads
Never ads, never sponsored links, never disguised commercial content. Children work, nothing distracts them.
Hosted in France
Any anonymous usage statistics remain on a server in France, with a French hosting provider.
Who is it for?
Students (ages 5–13)
Short, clear activities with immediate feedback. You can repeat as many times as you want, without pressure or public scoring.
Teachers
A filterable catalog by level and subject, immediate understanding, nothing to configure. Fits into a lesson, intervention, or substitute session.
Parents
A way to extend classroom work peacefully, without worrying what children are watching — there are only exercises on screen.
A collaborative project
PlumoBOX grows thanks to classroom feedback. Teachers, you are welcome to suggest new activities, report errors in exercises, suggest texts, images or themes, or simply share how a mini-app was used with your students. Every piece of feedback counts, and every idea can become an activity for the whole community.
