Privacy & demo data
The short version: the LensPDF demo runs entirely in your browser and keeps nothing. Your PDF never leaves the page. This page explains exactly what that means.
The marketing site
lenspdf.com is a static marketing site for the open-source LensPDF viewer. We don't run third-party analytics, we don't set marketing cookies, and we don't have a sign-up flow. The contact form sends your message via Resend to our inbox and stores nothing else.
The /demo page
The demo runs the viewer entirely in your browser. Page rendering, layer toggles, the densitometer, the TAC heatmap, the measure tool, color picking, and annotations all happen client-side against pdf.js — your file does not leave the page, and there is no backend to send it to.
Nothing you load in the demo is uploaded, stored, or transmitted anywhere. Close the tab and it's gone.
Self-hosting for sensitive content
Because the demo is fully client-side, you can evaluate it on any PDF without it leaving your machine. If you'd rather embed the viewer in your own stack, self-host the open-source release — the repo ships everything you need.
Questions & requests
For any privacy question — or to follow up on something you sent through the contact form — email privacy@thinkneverland.com . We'll action it within 30 days.
The product itself
LensPDF, the open-source viewer, has no telemetry and no phone-home. When you embed it in your own stack, nothing is sent back to us.
