Privacy Policy
The short version: your documents never leave your device.
Last updated: October 18, 2026
At a glance
- Your documents are processed in your browser and never uploaded to a server.
- We only collect anonymous usage statistics (page views and tool events) — never your content.
- No accounts, no tracking cookies.
What we collect
- Anonymous usage statistics, such as page views and tool events, to understand which tools are useful.
- We do not collect document content, files, names, email addresses or other personal information.
Local storage
- Interface preferences (theme, palette, font name) live in your browser’s localStorage and stay on your device.
- Clearing your browser data removes them at any time.
Font files
- “Load font file” registers a font in your browser only; the file is never uploaded.
Third-party resources
- MathJax is loaded from the jsdelivr CDN only when a document contains formulas; that request is subject to their privacy policy.
- Images hotlinked in your documents are served by their original sites.
Changes and contact
- Changes to this policy will be published on this page.
