Privacy
Your document belongs to you. OpenFile is built so we never receive it.
No server upload
File selection, parsing, rendering and search run in this browser. We do not send filenames, content or search terms to servers or analytics.
Data we do not retain
- Original files and document content
- Filenames and document metadata
- Search terms inside documents
Service analytics
We use Cloudflare Web Analytics and Google Analytics 4 to improve the service. They record visited pages, file-open attempts and outcomes, editor entry, and whether supported tools save a changed or newly generated file. File events include only the tool category (HWP, Markdown, PDF, or spreadsheet), the entry surface (home or tool page), and a fixed failure category. Google Analytics may use browser identifiers and cookies to distinguish visitors. Filenames, file contents, search terms, file sizes, and document metadata are never sent to analytics.
When you close the tab
HWP recovery data may remain in local browser storage. Markdown, PDF, and spreadsheet documents are not auto-saved. None is sent to a server or cloud storage.
