Privacy Policy

2. Information We Collect

We collect information that you provide to us directly or through automated technical means:

• Google Sign-In (optional): When you log in with Google, we receive your name, email address, and profile picture from Google. We use them to create your account, personalise your dashboard, and show your progress on the leaderboard. You can use all notes, papers, the Python Lab and the SQL Lab without logging in.
• School Name: If you add your school name, we use it for school rankings. Your name and school name may be shown on the public leaderboard.
• Study Activity: If you are logged in, we store the chapters you complete, your bookmarks and likes, and your quiz scores and points, so that you can continue where you left off.
• Messages You Send Us: When you use the contact form, ask a doubt, report an error, or give feedback on a chapter, we store your message together with any name or email address you include, so that we can reply and improve the notes.
• Log Files: Like most websites, our hosting servers automatically record technical information such as IP addresses, browser type, date and time of the visit, and the pages visited. This is used for security and to keep the website working properly.
• Python Lab: The Python Lab runs entirely inside your web browser. The code you type and run there is not sent to or stored on our servers.
• SQL Lab: The SQL Lab also runs entirely inside your web browser. The queries you run are not sent to our servers. The tables you create are saved only in your browser's local storage on your device; the Reset DB button or clearing your browser's site data removes them.

3. Cookies and Web Beacons

Cookies are small text files stored by your browser. We and our partners use them as follows:

• Essential Cookies: Used to keep you logged in, remember settings such as dark mode, and make the website work properly.
• Analytics (Google Analytics): We use Google Analytics to understand how visitors use CSIP12.in, for example which pages are visited, how long people stay, and what kind of device they use. Google Analytics uses cookies, and the information it collects is processed by Google. You can opt out by installing the Google Analytics Opt-out Browser Add-on.
• Advertising (Google AdSense): Third-party vendors, including Google, use cookies to serve ads based on your prior visits to CSIP12.in or other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the Internet.
• You may opt out of personalised advertising by visiting Google's Ads Settings page. You can also opt out of some third-party vendors' use of cookies for personalised advertising at www.aboutads.info.
• To learn more, see how Google uses information from sites or apps that use its services. You can also block or delete cookies in your browser settings, although some parts of the website may then not work as expected.

4. How We Use Your Information

We use the collected information for various purposes:

• To maintain and personalize your experience on the website.
• To display school rankings on the public leaderboard.
• To monitor website traffic, usage trends, and system performance.
• To reply to your messages and to correct and improve the notes.
• To show relevant, non-intrusive advertisements.
• To prevent spam and abuse and to keep the website secure.

5. Data Sharing and Protection

We do NOT sell, rent, or trade your personal data to any third parties. We never see your Google password: sign-in is handled by Google, and we only receive the details listed above. The website is served over a secure HTTPS connection, and access to our database is restricted.

You can ask us at any time to correct or delete your account and the data stored with it (your name, email, school, progress and scores) by contacting us using the details below.

6. Students Under 18

CSIP12.in is made for Class 11 and 12 students, so many of our users are under 18. Logging in is optional, and all notes, papers, the Python Lab and the SQL Lab can be used without an account. If you are under 18, please use the login, leaderboard and other features that use your personal information only with the knowledge and permission of a parent or guardian.

We do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe that your child has given us personal information, please contact us and we will delete it.

7. Changes to This Policy

We may update this Privacy Policy from time to time. The date at the top of this page shows when it was last changed.
