Privacy Policy
FlowDoc runs entirely in your browser. Your Markdown is never uploaded to our servers and is never used to train any model. We take your privacy seriously; this policy details how we handle data.
What we collect
- Anonymous analytics (page views, device type, browser type), collected by Vercel Analytics.
- Your email address and message content, only when you contact us.
How we use your data
- Anonymous statistics are used only to improve site experience and optimize features; they are never linked to your identity.
- Contact emails are used solely to respond to your inquiry and are never used for marketing or shared with third parties.

- Contact email content is deleted within 30 days after replying, unless you request otherwise.

Security measures
We take the following measures to protect your data: all pages are transmitted via HTTPS/TLS encryption; document conversion runs entirely in your browser sandbox with no server round-trip; we never store any user documents or conversion results. Nonetheless, internet transmission cannot be guaranteed absolutely secure, so we recommend caution with particularly sensitive content.
