Privacy Policy
Last updated: July 26, 2026Document input
Markdown, text, and HTML files you choose in the web app and text you paste there are processed only in this browser on this device and are not sent to lukurauha’s servers. Markdown passed to the MCP App’s read_document tool is sent to lukurauha’s Cloudflare Worker so the Reader can be displayed. The application does not save that document body to logs, a database, or object storage.
Browser data
Books, reading positions, bookmarks, theme choices, and typography settings are stored in localStorage. You can remove books from the bookshelf, and clearing browser data will also remove them.
Analytics
We use Cloudflare Web Analytics to understand site usage and display performance. This analytics service does not use cookies or localStorage and is not intended to identify you directly.
Contact form
The category and message you submit are stored in Cloudflare D1 so inquiries can be reviewed, used for improvements, and analyzed for trends. Screenshots are stored in a private Cloudflare R2 bucket and are also attached to the operator notification email. R2 images are deleted after 90 days, and original filenames are not stored. Notification email may be kept as long as needed for review. We use Cloudflare Turnstile to prevent abuse, but lukurauha does not store source IP addresses or verification data. Do not send text from documents you loaded, passwords, API keys or other secrets, or unnecessary personal information.
External links
Information handled by external sites is governed by each site’s own privacy policy.
Changes to this policy
We may update this policy when the service or the services it uses change. Updates will be announced on this page.
