At ZaiXian Tools (zaixianweb.com), your privacy is our priority. This policy explains what information we collect, how we use it, and how we protect your data when you use our website.
1. Information We Collect
1.1 Automatically Collected Information
Like most websites, we use standard web analytics (Google Analytics) that automatically collects certain non-personally identifiable information when you visit, including:
- Browser type and version
- Operating system
- Referring website / traffic source
- Pages visited and time spent
- General geographic location (country/city level only)
This information is aggregated and anonymized —it cannot be used to identify you personally.
1.2 Cookies
We use cookies solely for:
- Theme preference —remembering your dark/light mode choice
- Analytics —Google Analytics cookies to understand site usage
- Advertising —Google AdSense cookies to display relevant ads (see Section 3)
You can disable cookies in your browser settings at any time. Most tools work perfectly fine without cookies.
1.3 Tool Data —Your Content
All tools on ZaiXian Tools process your data entirely in your browser. This means:
- Images you compress never leave your device
- JSON you format stays on your computer
- Text you encode/decode is processed locally
- We do not upload, store, or have access to any content you process
You can verify this: disconnect your internet while using any tool —it will continue to work.
2. How We Use Your Information
We use analytics data solely to:
- Understand which tools are most popular so we can improve them
- Identify technical issues and fix bugs
- Improve the overall user experience
We never sell, trade, or share your personal data with third parties.
