Website Privacy Policy
This Privacy Policy describes how gwangy.com (the "Site"), operated by independent developer Glenn Yu (the "Operator"), collects, uses, and safeguards personal information when you visit and use our web services and developer tools.
Summary: Most web developer tools provided on this Site (JSON Viewer, Regex Tool, SQL Formatter, etc.) run purely in your local web browser (Client-side). Input for these local tools is not transmitted to or stored on our servers. Network tools and AI image generation use server processing as described below. The Site uses Google AdSense for advertising and Google Analytics for aggregated usage statistics, which may place and read third-party cookies.
1. Information We Collect and How We Collect It
- Automatically Collected Information: When you access the Site, our web servers and analytics tools may automatically log your IP address, browser type, operating system, referrer URL, timestamps, screen resolution, and cookie identifiers.
- Information You Voluntarily Provide: If you send inquiries via our contact form (Email modal), we collect your name, email address, and message content to address your request.
- Client-side Processing Guarantee: Text and code entered into our utility tools (including JSON Viewer, Regex Tool, SQL Formatter, Pixel Debugger, and Media Analyzer) are processed directly in browser memory without server transmission. Exceptions apply only to explicitly designated network functions, such as the API Mock Server echo endpoint and Server Ping latency checks.
- Server Processing for AI Image Generation: FLUX image generation (/image) uses server processing. Prompts and uploaded images are sent through the Site server to the image generation server. Generated images, prompts, and job history are processed and stored on servers and may appear in the public history screen or API. Do not submit personal information or confidential material.
