Privacy Policy

Last updated: 22 July 2026

This page explains how the Stack Visualizer at easystack.netlify.app handles information. The site is a free educational tool built and maintained by Arun Neupane. In short: the visualizer runs entirely in your browser, and we do not collect or store your personal data on any server.

What happens in your browser

Stack operations: every push, pop and peek happens locally on your device. The values you enter are never uploaded anywhere and disappear when you close the page.
Code snippets: the copyable code examples are static text served with the page. Copying them uses your browser's clipboard only.
Syntax highlighting: the code display uses the Prism library loaded from the Cloudflare CDN. When your browser requests those files, the CDN receives your IP address as part of a standard web request, as with any website resource.

Advertising and Google AdSense

This site may display ads served by Google, as a third-party vendor, using the Google AdSense program. In connection with serving ads:

Google and its partners may use cookies (including the DoubleClick cookie) to serve ads based on your prior visits to this and 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 at Google Ads Settings, and opt out of some third-party vendors' cookies at aboutads.info.
For more on how Google uses data from partner sites, see Google's Privacy & Terms.

Children's privacy

This is a general-audience educational tool and is not directed at children under 13. We do not knowingly collect personal information from anyone, children included.
