Privacy Policy for IDU+

Last updated: June 22, 2026

IDU+ is a browser extension that customizes and modernizes the visual interface of the IDU school portal. This privacy policy explains what the extension does, what information it stores, and what information it does not collect.

Summary

IDU+ does not collect, sell, share, transmit, or store personal user data on external servers. The extension works locally in the user's browser and is designed only to improve the appearance and usability of the IDU portal.

How IDU+ Works

IDU+ runs on IDU portal pages and applies a local visual layer to the existing portal. It may read the structure and visible content of the currently opened IDU page only so it can apply interface improvements, layout changes, and appearance settings.

IDU+ does not replace the official IDU portal, does not create a separate account system, and does not change school records or portal data.

Information Stored Locally

IDU+ stores appearance preferences using Chrome extension storage. These preferences may include:

• selected theme, such as light or dark mode
• accent color
• topbar color
• title font choice
• layout mode, such as portal or sidebar layout

These settings are used only to remember the user's customization choices and apply them consistently when the IDU portal is opened again.

Information IDU+ Does Not Collect

IDU+ does not collect or transmit:

• names, student identifiers, or other personally identifiable information
• usernames, passwords, authentication tokens, cookies, or login credentials
• messages, grades, attendance records, documents, profile information, or other school data
• browsing history
• financial information
• health information
• location data

No Analytics, Advertising, or Tracking

IDU+ does not use analytics, advertising systems, tracking scripts, or remote code. All JavaScript, CSS, fonts, images, and other extension assets are packaged with the extension.

Data Sharing

IDU+ does not sell, rent, transfer, or share user data with third parties. The extension does not send IDU portal data to any external service.

Permissions

IDU+ requests only the permissions needed to customize and modernize the IDU portal interface. Storage is used to save appearance settings. Access to IDU portal pages is used to apply the extension's visual improvements on the portal. The extension does not request access to all websites.
