Privacy Policy
Last updated: November 7, 2026
Nuniversity is a free educational website. The short version: your learning data stays on your own device, it is never sent to a server, and there are no accounts or analytics anywhere. This page gives the full picture.
What we collect: almost nothing
The Service has no backend that watches people, no analytics or tracking scripts, and no advertising. We never receive, store or share data about your learning, and nothing about you is for sale. No tracking cookies are served.
Your learning data lives in your browser
The Service stores progress and preferences on your device with browser local storage, so it works offline and keeps your place: courses and lessons completed, practice answers, your review schedule and streaks, tool and game settings, and language-course progress.
- That data never leaves your device: it is not sent to a server, cannot be read or synced by anyone else, and we hold no copy of it.
- To erase everything, clear the site data for this domain in your browser ("Clear browsing data" / "Clear site data"). The deletion is absolute: there is no backup on our side.
Contact and partnership inquiries
The partners page runs a contact form delivered through Formspree; email works instead. If you write to us, we receive what you choose to share: name, email, organization and message. We use it only to reply, and we delete it on request (write to the same address).
Donations
Donations are processed entirely by your bank through PIX or PayID. We never receive payment credentials, and payments do not create any database entry about you on our side.
Third-party embeds
Lessons embed educational content served by other providers: YouTube in privacy-enhanced mode, PhET interactive simulations, molecular structure files and similar. Those providers deliver the video or simulation from their own servers when the material is displayed, so their servers may log the request or set cookies under their own policies. External pages linked from lessons follow their own policies.
Children
The Service is a general-audience educational website. It requests no personal data from anyone, including children, and it does not target or profile any age group.
Security
The Service is a fully static website: there is no central user database to break into. Delivery to your browser runs over HTTPS.
Changes
If this policy changes, the new version appears on this page with a newer "Last updated" date.
