Support the mission
Every child deserves a good first teacher.
BubaKey was born at home, made by a parent to teach their own child. The dream is bigger: bring AI-powered learning to children who would never have access to it, in Brazil, Portugal, Angola, Spain, Italy, the US, China and beyond.
We are not a non-profit yet, so we do not ask for donations. When the organisation exists on paper, we will say so here, with open accounts.
- 1Products that teach and pay for themselvesWe are here
- 2A community that believes and helps
- 3A non-profit for learning with AI

Questions parents ask
Can my child really not close anything?
BubaKey goes full screen and captures the keyboard and mouse, so normal presses never reach your apps. No app can block every system shortcut (like Ctrl+Alt+Del), so stay nearby, as you would anyway.
Which devices work?
Any laptop with a modern browser: Windows, Mac and Chromebook. Google Chrome locks best. On tablets and phones it works too, with the padlock to exit.
Do you collect data about my child?
No. The account belongs to the grown-up. We never ask for your child’s name, photo or voice, and there are no ads inside the game.
Is calm mode a therapy?
No. Calm mode simply reduces stimulation: no flashing, softer sounds, slower animations. It can help children who get overwhelmed easily, but it is not a treatment and we do not promise therapeutic results.
How do I cancel?
One click in your account, any time. No calls, no forms.
