1. About SQLHub
SQLHub is an educational website that helps users learn SQL by solving real query problems. The site provides SQL practice questions, table schemas, sample data, expected output, correct answers, explanations, common mistakes, and related database concepts.
SQLHub is currently built as a static website. It does not require users to create an account, log in, make a payment, or submit profile information to use the learning content.
2. Personal Information We Collect
SQLHub does not intentionally collect sensitive personal information through the website itself. Because the site has no account system, comment system, or user database in the initial version, users can read content and practice SQL without directly providing a name, address, phone number, or password.
If a user contacts SQLHub by email, the email address and any information included in the message may be used only to read, manage, and respond to the inquiry.
3. Automatically Processed Technical Information
When users visit a static website, hosting providers, security services, or browser technologies may process technical information such as IP address, browser type, device type, referring page, pages visited, and access time. This information may be used for security, troubleshooting, analytics, spam prevention, and service reliability.
If SQLHub is hosted on Cloudflare Pages or a similar hosting platform, that provider may process logs and technical data according to its own privacy policy and service terms.
4. Cookies and Similar Technologies
SQLHub may use browser storage for simple user preferences such as a light or dark theme. This preference is stored locally in the user's browser and is not used to identify the user personally.
SQLHub may use third-party services such as Google AdSense or Google Analytics. These services may use cookies, web beacons, or similar technologies to provide ads, measure traffic, prevent abuse, limit repeated advertising, or understand how visitors use the site.
5. Advertising and Google AdSense
SQLHub may use Google AdSense. Google and other advertising partners may use cookies to serve ads based on a user's visit to SQLHub or other websites. Advertising providers may use information that does not directly identify a person to show relevant ads and measure ad performance.
SQLHub will not ask users to click ads and will not intentionally encourage invalid traffic. Advertising areas should be placed in a way that does not mislead users or interfere with learning content.
6. Analytics
SQLHub may use analytics tools in the future to understand which pages are useful, which topics need improvement, and how the site performs across devices. Analytics tools may collect aggregated usage information such as page views, session duration, approximate location, browser type, and device category.
Analytics information should be used to improve the website and learning experience, not to collect unnecessary personal details.
7. How Users Can Control Cookies
Users can control or disable cookies through their browser settings. Most browsers allow users to block cookies, delete existing cookies, or receive a warning before cookies are stored.
Disabling cookies may affect some third-party services, analytics features, advertising personalization, or saved preferences, but the core static learning content should remain available.
8. Third-Party Links
SQLHub may link to external resources, documentation, tools, or database vendor websites. These third-party websites have their own privacy policies and terms. SQLHub is not responsible for how external websites collect, use, or protect information.
9. Data Retention
Email inquiries may be retained for a reasonable period to respond to the user, track site feedback, or improve content quality. Technical logs may be retained by hosting, analytics, security, or advertising providers according to their own policies.
10. Children's Privacy
SQLHub is a general educational website about SQL and databases. It is not designed to knowingly collect personal information from children. If the site owner becomes aware that personal information from a child has been provided, the owner should take reasonable steps to delete it.
