Privacy policy

Information used by this website
Reading public articles does not require an account. If you register, the application stores your name, email address and a password hash. It also stores saved topics, practice answers, session results and test timing so your learning activity can be displayed when you return. Administrators can manage accounts and review learning activity to operate the service.
Sign-in cookies and security records
The website uses a first-party session cookie to keep you signed in. Sessions expire after approximately twelve hours and signing out revokes the current session. Rate-limit records help protect sign-in and editing actions. Administrative changes are recorded in an activity log. Hosting infrastructure may separately record technical requests such as IP addresses and browser information.
YouTube and external destinations
When published videos appear, their thumbnails load from YouTube image servers. This sends a request, including normal connection information, to that provider. Selecting a video opens YouTube, where Google's privacy policy and YouTube's settings apply. No YouTube player is automatically embedded by this application.
Advertising and analytics
This package does not enable advertising or third-party analytics scripts by default. If the operator adds these services, this policy and any required consent controls must be updated before those services are activated. Advertising cookies and data practices depend on the provider and deployment configuration.
Access, correction and deletion
Use the contact details published on the contact page to request access, correction or deletion of account information. The operator may need to verify account ownership. Account and learning records remain stored until the operator removes them; backup copies may remain until the corresponding backup is replaced or deleted. Do not submit sensitive personal information in learning content or feedback.
Policy updates
The operator should keep this page aligned with the actual hosting, retention and third-party services in use. The revision date shown on this page indicates the most recent saved change.
