2. What we collect
- What you send us: name, email and phone when you fill in a contact or partnership form.
- Purchase data: in our store, the data required for invoicing and delivery (including Brazilian tax IDs, where legally required).
- Technical data: browser information and pages visited, in aggregate, to keep the site running and improve it.
3. Children
Our educational content is aimed at children, but we do not collect personal data from children. Games and stories work without sign-up.

- Legal obligation: tax invoicing and record keeping.
- Legitimate interest: site security and content improvement, always in aggregate.
- Consent: optional cookies and communications you choose to receive.
5. Sharing
Only with providers required to operate: hosting, payment providers, carriers and the invoicing system. We do not sell personal data.
6. Cookies
We use essential cookies (navigation, cart and login) and, with your consent, performance cookies. You may accept, reject the optional ones or change your preferences at any time — reopen cookie preferences.
7. Your rights
Under the LGPD you may request confirmation of processing, access, correction, anonymization, portability, deletion, information about sharing, and withdrawal of consent. Write to info@oxigenius.org — we reply within 15 days.
