Privacy Policy

Last updated: 19 September 2026

This policy explains what information is collected when you use ersahilkagyan.com ("the website", "we"), run by Sahil Khan (Er Sahil Ka Gyan). By using the website you agree to this policy.

Information we collect

You can use the website without creating an account or giving us personal information. We do not ask for your name, phone number or email to download notes or papers.

Like most websites, our hosting provider (Hostinger) automatically records standard server logs: IP address, browser type, pages requested, referring page and the date and time of the visit. These logs are used for security and to keep the website running, and are not used to identify you.

If you contact us through social media, we receive the information you choose to send and use it only to reply.

Cookies and advertising

We use Google AdSense to show ads, which helps keep the website free. Google and its partners are third-party vendors that use cookies to serve ads based on your previous visits to this website and other websites.

• Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the Internet.
• You can opt out of personalised advertising by visiting Google Ads Settings. You can also opt out of some third-party vendors' use of cookies for personalised advertising at www.aboutads.info.
• To learn how Google uses information from sites that use its services, see How Google uses information from sites or apps that use our services.

You can block or delete cookies in your browser settings. The website will still work, though ads may be less relevant.

Embedded content

Some pages embed YouTube videos and link to files on Google Drive. These services may set their own cookies and collect data under their own privacy policies when you interact with them.

Children's information

The website is meant for college students. We do not knowingly collect personal information from children under 13. If you believe a child has shared personal information with us, contact us and we will delete it.

Your rights

Because we do not store personal accounts, there is usually nothing about you to access or delete. If you have sent us something and want it removed, contact us through the contact page.
