Privacy Policy
The short version 👋
- You don't need an account, and we never ask your name, email or age.
- No cookies, no ads and no tracking. We only count visits, anonymously.
- Your stars, badges and settings stay on your own device. We can't see them.
- We don't sell or share anything about you, because we don't collect it.
This policy explains what happens to information when you use Jugnix at jugnix.com. Jugnix is used by children, so we have kept it short and written it in plain language. If you are a student, you might like to read it with a parent or teacher.
1. Information we collect
We do not collect personal information. Jugnix has no sign-up, no login, no forms and no comments. We don't use cookies, advertising or tools that follow you around the web. Our fonts are stored on our own site too. The only thing we measure is anonymous visit counts, explained in section 3.
2. What's saved on your device
To remember your progress, the site saves a few small notes in your browser's local storage. They stay on your device and are never sent to us or anyone else. They don't contain your name or anything that identifies you.

To delete them, clear this site's data in your browser settings (often called "Clear browsing data" or "Site settings"). Your stars will reset to zero. Because they live in one browser, they don't follow you to another phone or computer.
3. Anonymous visit counts
To learn which simulations students use most, we use Vercel Web Analytics, from our hosting company Vercel. It counts page visits without cookies and without storing your IP address. Each visit is linked to a scrambled code that changes every day, so nobody, including us, can recognise you or follow you over time or across other websites.
We only see totals, such as how many people opened a page, which website linked to it, and the country, browser and type of device visitors used. We don't use this information for advertising.
4. Technical information our host sees
Like every website, Jugnix runs on servers from a hosting company (Vercel). When your browser asks for a page, those servers may automatically record standard technical details such as your IP address, browser type, the page requested and the time. This is needed to deliver the site and protect it from attacks. These logs are kept for a limited time by the host, and we don't use them to identify or profile anyone.
5. Children's privacy
Jugnix is made for school students, including young children. Because we collect no personal data, a child can use every part of the site without sharing anything about themselves. Visit counts are anonymous totals; we do not track any individual child's behaviour or show anyone targeted advertising.
If we ever add features that need personal data, such as accounts, we will update this policy first and, as India's Digital Personal Data Protection Act, 2023 requires, ask for verifiable consent from a parent or guardian before collecting any personal data from anyone under 18.
6. Links to other websites
If a page links to another website, that site has its own privacy policy. We aren't responsible for how other websites handle information.
7. Changes to this policy
If we change this policy, we will update it on this page and change the "Last updated" date above. If the change is important, such as starting to collect any personal data, we will also announce it on the home page.
8. Questions and complaints
We will add a way to contact us about privacy on this page soon. Parents and teachers are welcome to get in touch once it is here.
