About PlumoBox

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.

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.

• 

  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.

• 

  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.

Frequently asked questions

A few practical answers to get the most out of PlumoBox, at school or at home.

• Do I need to create an account to use PlumoBox?▾

  No. No account, no sign-up, no password. Just open the site, pick a mini-app from the catalog, and start straight away.
• Is there a teaching guide for using PlumoBox in the classroom?▾

  Yes. The menu has a Pedagogical Guide that links the mini-apps to the official curriculum (French Education Ministry, 2025/2026), covering seven subjects from ages 5 to 13. The guide is currently being written and is only available in French for now.
• How do I switch an activity to full screen?▾

  Each mini-app has a full-screen button to the left of its title. It hides the browser and the site interface so only the activity remains, which is very useful on an interactive whiteboard or a projector. Press Esc to exit at any time. The browser's F11 key does the same at the window level.
• How do I enlarge the display to see the exercises better?▾

  To zoom in your browser, use Ctrl + mouse wheel (Cmd + wheel on Mac), or the keyboard shortcuts Ctrl + and Ctrl - to zoom in or out. Ctrl 0 resets the display to 100%. Very handy when projecting an activity to the back of a classroom.
• Can I switch to dark mode?▾

  Yes. A sun/moon button at the top of the page toggles between light and dark. Your choice is remembered in your browser. By default, the site follows your device's system preference.
• Is sound required?▾

  Never. Sound is always a complement, never the primary information channel. It is muted by default and a button lets you turn it on if you wish. Every activity works without sound.
• Does the site read text aloud?▾

  Yes, on certain mini-apps designed for non-readers or dyslexic students (confusable letters, silent dictation, sight words, etc.). A 🔊 button speaks a word or sentence. The voice is synthesised locally in the browser, in French only for now: no data is sent to a third-party server. The voice file downloads on first use, after which everything works offline.
• Does PlumoBox work without an Internet connection?▾

  Yes. PlumoBox is an installable web app (PWA): on first visit, the site is cached in your browser. Subsequent visits work without an Internet connection. On Chrome and Edge, an 'Install' button lets you launch it like a standalone app. A native mobile version with all resources bundled is still in preparation.
• Is the site usable on a tablet or smartphone?▾

  Yes. PlumoBox is built for the classroom tablet first and foremost. Touch targets are large (at least 44 pixels), activities are fully touch-driven, and there is nothing to install. On a smartphone, some mini-apps feel cramped but remain playable.
• Does the site store anything about students?▾

  No personal data. No name, no first name, no address, no persistent identifier. A few preferences (theme, school level, sound, best scores) are kept in the browser of the device and never leave that machine. See the legal notice for the details.
• How do I report a mistake in an activity?▾

  The best way is the Contact page: mention the mini-app, the chosen level, and what is wrong (a screenshot is appreciated). Classroom feedback is precious and is always handled quickly.
• How do I suggest a new mini-app?▾

  Any idea is welcome: write via the Contact page describing the activity, the target level, and what it brings to students. Teachers who would like to contribute content (texts, images, exercises) are also invited to get in touch. The project is open.
