This page explains the data flows in douni.one: tool input, browser storage, and the services used for advertising, analytics and diagnostics.
Content reviewed
Tool input
WebP conversion, image compression and JSON/CSV conversion process input in your browser. Some code converters, including TypeScript and Sass tools, send input to site API endpoints. Loading code, fonts or other resources still makes network requests.
Browser storage
Some editors keep input in session storage so it can reappear after a reload or in a related tool in the same tab. Theme preferences may be saved locally. Clear editor input and site data when using a shared device.
Advertising and diagnostics
The site integrates Google AdSense, Google Analytics, Microsoft Clarity, Vercel Analytics and Speed Insights, and Sentry error monitoring and session replay. These services may process usage, device and diagnostic data and use cookies or similar technologies. Their policies are linked below; browser-side conversion does not mean the whole site makes no external requests.
