Information We Collect
We process only information you provide or generate through site use that is reasonably needed to deliver the service.
- Names, display names, email addresses, and contact details provided for registration, sign-in, consultations, or subscriptions.
- Course access, learning progress, favorites, orders, and support communications.
- Access logs, device and browser information, necessary cookies, and troubleshooting data.
How We Use Information
We use this information to provide and improve site features, deliver purchased content, respond to support requests, protect accounts, and meet applicable compliance obligations.
Storage and Protection
We apply access controls and safeguards appropriate to the sensitivity of the information, and limit processing to people or services with a genuine operational need. Internet transmission cannot be completely secure, so we continue to reduce foreseeable risks.
Retention and Deletion
We retain information only as long as needed for the purposes described here, transaction and dispute handling, or applicable legal duties. After that, we delete, anonymize, or otherwise restrict it.
Your Rights
You may contact us to request access, correction, or deletion of personal information, withdraw consent where available, or stop non-essential messages. Identity checks, transaction records, or legal duties may limit some requests.
Third-Party Services
The site may use hosting, authentication, payment, content management, email, or analytics providers. They process information only as needed for their role and under their own privacy terms; this policy does not promise or control their independent conduct.
