Cookie Policy

This Cookie Policy explains how IK Learning uses cookies and similar technologies, such as browser local storage, when you visit our Class 9 and Class 10 Computer Science notes. It sits alongside our Privacy Policy.

What Cookies Are

A cookie is a small text file that a website asks your browser to store on your device. Cookies are widely used to make sites work, to remember your preferences, and — in the case of advertising — to decide which ads to show you. Local storage works similarly but keeps the data on your device without sending it back to a server with every request.

You Do Not Need an Account

IK Learning does not require you to register, sign in, or submit personal details to read anything on this site. We do not set our own tracking or analytics cookies, and we do not sell any information about you.

What This Site Actually Uses

• Theme preference

  Local storage (first-party)

  Remembers whether you chose light or dark mode so the site looks the same on your next visit. Stays on your device and is never sent to us.

• Saved chapters

  Local storage (first-party)

  When you use the Save button on a chapter page, a marker is stored in your own browser so the page shows as saved next time. It stays on your device, is never sent to us, and clearing your browser data removes it.

• Google AdSense / DoubleClick

  Third-party advertising

  Set by Google when advertising is served. Used to show ads, limit how often you see the same ad, and measure ad performance. Google may use these to personalise ads based on your prior visits to this and other websites.

• Hosting and security logs

  Server-side (no cookie)

  Our hosting provider keeps standard technical logs such as IP address and browser type to keep the site running and protect it from abuse.

Advertising Cookies and Google

We use Google AdSense to help keep this site free. As a third-party vendor, Google uses cookies — including the DoubleClick advertising cookie — to serve ads on this site. 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 can read how Google uses information from sites that use its services at policies.google.com/technologies/partner-sites.

How to Control or Opt Out

You are in control. Any of the following will limit or switch off advertising cookies:

• Turn off personalised advertising in Google Ads Settings.
• Opt out of participating vendors via the Network Advertising Initiative or YourAdChoices (DAA).
• Block or delete cookies in your browser settings. Instructions for every major browser are collected at allaboutcookies.org.
• Clear your browser's local storage to reset the saved light/dark theme preference.

Blocking advertising cookies does not stop you seeing ads — it just means the ads you see will be less relevant. All of the study material on this site remains fully available either way.

Visitors in the EEA, UK and Switzerland

Where consent is required by law before advertising cookies may be set, our advertising partner presents a consent message and records your choice. You may change or withdraw that choice at any time using the privacy or consent option shown by that message, or through the browser and Google controls listed above.

Changes to This Policy

We may update this Cookie Policy as the site or its advertising partners change. Any update will appear on this page with a new revision date.
