Privacy Policy for COSE - 多平台文章同步
Last Updated: December 13, 2025
Overview
COSE (Create Once, Sync Everywhere) is a browser extension that helps users sync articles from the md.doocs.org Markdown editor to multiple publishing platforms. We are committed to protecting your privacy.
Data Collection
We do not collect any personal data.
COSE operates entirely locally within your browser. The extension:
- Does NOT collect personally identifiable information
- Does NOT collect health, financial, or authentication information
- Does NOT track your browsing history or web activity
- Does NOT send any data to external servers
- Does NOT use analytics or tracking services
Data Usage
All data processed by COSE remains on your local device:
- Article Content: Your article title, body, and formatting are only read from md.doocs.org and transferred directly to the target publishing platforms within your browser.
- Login Status: The extension checks login cookies on target platforms (CSDN, Juejin, WeChat, etc.) solely to verify if you are logged in. This information is not stored or transmitted.
- User Preferences: COSE does not persist user preferences or settings.
