Privacy Policy

Last updated: August 24, 2026

NexaLab.app (the "Site") is a blog and free utility service planned, built, and operated individually by Kim Ho-gyun (the "Operator"). The Operator takes user privacy seriously, and this Privacy Policy explains transparently what information is collected and how it is used.

1. Information We Collect

Automatically collected information

When you visit the Site, Google Analytics and Google AdSense may automatically collect information such as your IP address, cookies, browser/device information, pages visited, and time spent on the Site.

Information you enter into AI tools

Text or files you enter or upload into free tools such as the AI Quote Generator, Profit Calculator, SEO/GEO Checker, llms.txt Generator, and Report Checker are used only in server memory while the request is being processed, and are discarded immediately once a response is returned. This content is never stored in any database.

Minimal information stored as an exception

  • SEO/GEO Checker: to avoid redundant re-analysis, only the checked URL and its scores are cached for up to 24 hours before expiring automatically. This information does not include personal data.
  • Abuse prevention: some tools temporarily keep your IP address in server memory for up to 24 hours to prevent excessive requests; this is never written to a database.

Administrator account information

A separate login account (email, password) used by the Site operator to manage content is handled through Supabase Auth. This is operator-only information and unrelated to regular visitors.

2. Purpose of Collecting and Using Information

  • Analyzing site traffic and improving service quality
  • Serving ads and personalized advertising (Google AdSense)
  • Preventing abuse and excessive requests on free tools
  • Responding to user inquiries

3. Retention Period

In principle, personal information is not stored separately, and content entered into AI tools is discarded immediately after a response is returned. SEO/GEO Checker cache data is kept for up to 24 hours, and IP information used for abuse prevention is kept for up to 24 hours before automatic deletion. The retention period for cookies collected by Google Analytics and Google AdSense follows each service's own policy.

4. Third-Party Sharing and Processing

The Operator does not share user information with external parties in principle. However, the following services are used to operate the Site, and each handles information under its own privacy policy.

  • Google Analytics (traffic analytics)
  • Google AdSense (ad serving)
  • Supabase (blog content and tool-result cache storage)
  • Vercel (site hosting)

5. Cookies: Use and Opt-Out

The Site uses cookies issued by Google Analytics and Google AdSense to analyze traffic and serve personalized ads. You can decline cookies through your browser settings, though some features may be limited as a result. Settings such as dark mode and tool history are stored only in your browser's local storage (localStorage) and are never sent to a server.

6. Your Rights

You may inquire about the status of your personal information at any time. Please reach out using the contact information below, and we will respond promptly.

7. Security Measures

The Site is designed around a "no-storage" principle that avoids storing personal information whenever possible, fundamentally reducing the risk of a leak. Features that require database write access use server-only keys that are never exposed to the client (browser).

8. Children's Privacy

The Site does not offer services specifically targeted at children under 14 and does not knowingly collect information from children.

10. Changes to This Policy

Any changes to this Privacy Policy will be announced on the Site.

9. Privacy Contact
