Privacy Policy

Effective Date: 2026-09-18

Welcome to GitHub City ("we", "us", "our"). This Privacy Policy explains how we collect, use, disclose, and safeguard information when you visit githubcity.blog and use the embedded GitHub City 3D contribution graph experience (the "Service"). If you have questions, contact [email protected].

1. Information We Collect

  • GitHub Username Input: The embedded GitHub City tool may ask for a GitHub username to generate a 3D contribution city. Do not enter private secrets, passwords, tokens, or sensitive information.
  • Usage and Device Data: We may receive standard technical data such as IP address, browser type, device type, pages visited, referrer, and time on page.
  • Analytics Data: We may use analytics tools to understand site performance, navigation patterns, and content usefulness.
  • Support Communications: If you email us, we collect the email address and message content needed to respond.

2. How We Use Information

  • Provide and maintain the githubcity.blog website.
  • Improve page performance, usability, and GitHub City explanatory content.
  • Understand whether visitors can access and use the embedded tool area.
  • Respond to support, correction, and feedback requests.
  • Protect the Service, prevent abuse, and comply with legal obligations.

3. GitHub Profile and Contribution Data

GitHub City visualizations are based on GitHub activity associated with the username entered into the tool. Public GitHub profile and contribution information may be retrieved or displayed by the embedded tool. We do not ask for your GitHub password or personal access token.

4. Cookies and Analytics

We may use necessary cookies or similar technologies for website operation and analytics cookies to understand aggregate usage. You can control cookies through your browser settings. Blocking cookies may affect some analytics or site functionality, but the main page content should remain accessible.

5. Google Advertising and Third-Party Cookies

If advertising is displayed on githubcity.blog, Google and its advertising partners may collect or receive information about visits, ad impressions, and interactions. This may include IP address, cookies, web beacons, device or browser information, and other identifiers used to deliver, measure, prevent abuse of, or personalize advertising where permitted.

Google and other third-party vendors may place and read cookies on a visitor's browser, or use similar technologies, to serve and measure ads. You can learn how Google uses information from sites and apps that use its services in the Google partner-sites policy. You can also manage some ad-personalization choices through your browser or Google's advertising settings.

6. Embedded Third-Party Content

The homepage embeds the GitHub City tool from a third-party GitHub Pages URL. Embedded content may be served under the third party's own technical infrastructure and policies. We do not control every data practice of external hosts, GitHub, or open-source project maintainers.

7. Sharing and Disclosure

  • Service Providers: Hosting, analytics, security, or infrastructure providers may process data as needed to operate the website.
  • Legal Requirements: We may disclose information if required by law or to protect rights, safety, and security.
  • Business Transfers: If the website is transferred, relevant operational data may be transferred as part of that transaction.
  • No Sale of Personal Data: We do not sell personal information.

8. Data Retention

We retain support emails and technical logs only as long as needed for the purposes described above, unless a longer period is required by law. Data handled by embedded third-party content is subject to the relevant third party's practices.

9. Your Rights

Depending on your location, you may have rights to access, correct, delete, or object to certain processing of personal data. To make a request, contact [email protected].

10. Children's Privacy

githubcity.blog is not directed to children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided personal information, contact us so we can review and delete it where appropriate.

11. Security

We use reasonable technical and organizational measures to protect the website and information we process. However, no internet transmission or storage method is completely secure.

12. International Processing

Information may be processed in countries other than where you live. Where required, we use appropriate safeguards for cross-border processing.

13. Changes to This Policy

We may update this Privacy Policy from time to time. Material changes will be reflected by updating the Effective Date above.
