CQBase Website Privacy Policy

Data We Process

You can browse public question banks, topic pages, single-question explanations, study pages, the About page, and the Contact page without logging in.

If you create an account or use Google sign-in, we process email address, nickname, preferred language, login state, practice progress, missed-question records, and mock-exam records so we can sync study state, restore records, and protect account security.

Ads And Cookies

The CQBase website may display ads through Google AdSense. Google and its partners may use cookies, advertising identifiers, IP address, browser information, page views, and ad interaction data for ad delivery, measurement, fraud prevention, and service security.

You can manage personalized advertising through browser settings, Google ad settings, or consent controls available in your region. Blocking or clearing cookies may affect advertising and login behavior, but public question-bank content remains available.

Email And Feedback

If you contact us at [email protected], we process the email address, issue description, page URL, question number, screenshots, or other support material you choose to provide.

We use that information only to reply, correct question-bank content, handle privacy requests, troubleshoot technical issues, and maintain website safety.

Data We Do Not Actively Collect

The CQBase website does not actively request or collect:

• Precise location
• Contacts, SMS messages, photos, videos, or local files
• Health, financial account, government ID, or biometric data
• Sensitive personal details unrelated to amateur radio study

Sharing And Retention

We do not sell personal data. To operate the site, data may be processed by hosting, database, email, Google sign-in, Google AdSense, and security or diagnostics providers as needed.

Account, practice, and missed-question data is kept until you delete the account data or request deletion. Server logs, support emails, and security records are retained for reasonable periods for troubleshooting, fraud prevention, compliance, and operations.

Your Choices

You can use the public question-bank content without logging in. You can clear browser cookies, sign out, stop using sync features, or email us to request access, correction, deletion, or restriction of your data.

For account-data deletion requests, include the login email or enough information for us to locate the record. We will respond within a reasonable time and explain any legal or security records that cannot be deleted immediately.

Children And Third-Party Links

CQBase is intended for users preparing for amateur radio exams and studying radio knowledge. It is not specifically directed to children.

The website may link to official exam authorities, Google services, or other third-party pages. Those pages are governed by their own policies.
