Privacy Policy
Last updated: May 28, 2026
1. Our Privacy Philosophy
QingChuan Toolbox is designed around a simple principle: your data should never leave your computer. Every tool on this site processes files and data locally in your browser using JavaScript and WebAssembly. Nothing is uploaded to any server.
2. No Data Collection
We do not collect, store, or process personal information. No user accounts, no sign-ups, no databases. The tools work entirely client-side. When you close the tab, everything is gone.
3. Cookies & Analytics
We may use Google Analytics for anonymous usage statistics. You can disable cookies in your browser settings.
4. Advertising
We display ads through Google AdSense on non-tool pages. Tool pages themselves are ad-free to ensure a clean user experience.

How We Handle Your Data
QingChuan Toolbox is designed with privacy as a core principle — not an afterthought. Here is exactly what happens with your data for each tool category:
- Image tools: Images are loaded into browser memory using the FileReader API. Processing happens via Canvas API. Nothing is uploaded. When you close the tab, everything is gone.
- Text tools: Text you type stays in your browser's DOM. No keystroke logging. No server communication.
- Calculators: All calculations run in JavaScript in your browser. No inputs are collected.
- AI generators: Our generators use local template systems — no API calls to external AI services. Your topics and preferences stay on your device.
Third Parties
