Privacy policy, version 1.0

In short

• You can read every page without an account, and you never have to tell us who you are.
• Reading pages set no cookies and load no analytics, advertising or tracking scripts.
• Your browser can keep your colour theme and your study checklist ticks for you. They never leave your device.
• If you write to us, we use your message only to reply and to fix the page.

Who we are

This policy covers the TopicLamp website. TopicLamp decides how the information described here is handled. To ask anything about it, write to hello@topiclamp.com.

What we do not collect

There is no sign-up, no login, no comment box and no form on the site. We do not ask for your name, phone number, school, exam roll number or any payment details, and we do not buy or receive information about you from anyone else.

What your browser stores

Your browser can keep these things for you, on your device only. None of them is ever sent to us or to anyone else, and none of them is a cookie.

• Your colour theme. If you choose Light or Dark in the theme switch, your browser saves that choice in its local storage under the name “tl-theme”, so the next page opens in the same colours. Choosing Auto removes it.
• Your study checklist. If you tick topics as done on a syllabus page or a topic page, your browser saves the list of ticked topics under the name “tl-done”. It also saves the last syllabus page you ticked on, with how many of its topics you have ticked, under “tl-last”, so the home page can offer “Continue where you left off”. “Clear ticks” on any syllabus page removes both.
• Your place on a topic page. On a topic page with More practice, once those questions have loaded (they load by themselves as you scroll near them, or when you press “Show more practice”), that browser tab remembers how far down the page you were, in its session storage under “tl-more:” and the page address, so a reload or the Back button returns you to the same place. Your browser deletes it when you close the tab.

Clearing your browser’s data for this site deletes all of them. The site sets no cookies.

What reaches the servers when you open a page

Like every website, our pages are delivered by hosting and content delivery providers. To send you a page they receive the technical details of your request: your IP address, the page address, the time, and your browser’s name and version. Their systems may keep these details in logs for a limited time to run and protect the service.

We do not use these details to find out who you are, we do not combine them with other information, and we never sell them.

When you write to us

“Report a mistake” opens your own e-mail app with a message addressed to us; nothing is sent until you send it. When you write to us, we receive your e-mail address and your message. We use them only to reply to you and to correct the page, keep them only as long as that takes, and share them with no one unless the law requires it.

Students under 18

Many of our readers are school students. The site works fully without giving us any personal information. If you are under 18 and want to write to us, please ask a parent or guardian to write for you or with you.

Your choices and rights

You can ask us what personal information we hold about you (in practice, only e-mails you have sent us), and ask us to correct or delete it. Where India’s Digital Personal Data Protection Act, 2023 applies, these are also your rights under it. To make a request, write to hello@topiclamp.com.

Other websites

Our pages link to official sites such as ncert.nic.in and nta.ac.in. When you open them, their own privacy policies apply.
