Privacy Policy - Find Nuclei Viewer

1. Overview

                Find Nuclei Viewer is designed with privacy first. No account is required, no
                personal information is collected, and your image data never leaves your browser.
            

2. Analytics We Collect

We use Plausible Analytics, a privacy-friendly analytics service hosted in the EU. Plausible does not use cookies and does not collect personal data.

Plausible collects:

Page views (which pages are visited)
Referrer (how you found us)
Browser and operating system type
Country (derived from anonymized IP; IP is not stored)
Screen size category (mobile/tablet/desktop)

Plausible does not collect:

IP addresses
Personal identifiers
Cross-site tracking data
Any information about the images you view

3. Data Stored in Your Browser

The viewer stores data locally in your browser to provide a smooth experience. This data never leaves your device.

Storage	What	Purpose
IndexedDB	Image metadata, thumbnails, viewer settings, annotations	Remember recently opened images and restore your last view
localStorage	UI preferences (e.g., welcome modal dismissed, storage notice)	Remember small UI choices across sessions
File System Access API	Directory handle references (Chrome/Edge only)	Re-open local ZARR folders without re-selecting them

4. Your Image Data

                Your microscopy data is processed entirely in your browser using WebGPU/WebGL.
                Image files are never uploaded to any server. When loading from a URL, your
                browser fetches data directly from that URL — Find Nuclei does not proxy or
                store any of it.
            

5. Cookies

We do not use cookies. Plausible Analytics is cookieless by design. No third-party cookies are set by this site.

The only third-party service we use is:
