Section 6 - Cookies and Tracking Technologies

Cookies are files with a small amount of data, which may include an anonymous unique identifier. Cookies are sent to your browser from a website and stored on your computer's hard drive. We use cookies to enhance your browsing experience and collect information about how visitors and students use our Services.

Website and School: We use cookies to enhance your browsing experience, keep you logged into your account, remember your preferences, and analyze how students use our courses.

This cookie is required for the Tools Hub to function and cannot be disabled without preventing login.

If you are using one of the common Internet web browsers, you can set up your browser to either let you know when you receive a cookie or to deny cookie access to your computer. Most web browsers allow some control over cookies through browser settings, including the ability to accept or reject cookies, delete existing cookies, and receive notifications when cookies are sent. However, if you do not accept cookies, you may not be able to use some portions of our Services.

Specifically, accounts whose access has been expired or revoked for more than 6 consecutive months are subject to permanent data deletion during routine database maintenance, without further notice. We are not obligated to retain your content indefinitely for inactive accounts.

Section 8 - Data Security

The security of your personal information is important to us. We implement reasonable and industry-standard security measures to protect your information against unauthorized access, alteration, disclosure, or destruction, including:

Encrypted payment data handling in accordance with PCI-DSS standards;
Access controls limiting who can view your data; and
Regular security reviews of our infrastructure.
