Accessibility, Privacy, and Security#

These pages make explicit what Cellucid does and does not do in two areas that often get skipped in visualization tooling:

  • Accessibility: how to produce figures and workflows that work for diverse readers (color vision deficiency, low vision, keyboard-only use), plus current limitations of a WebGL canvas-based UI.

  • Privacy model: what stays local, what can touch the network depending on your loading workflow, what is stored in the browser, and what exported artifacts can contain.

If you are in a regulated environment (clinical, IRB-controlled, corporate IP), the key idea is:

Cellucid is “just a web app”, but your workflow choices determine what leaves your machine and what gets saved into shareable artifacts.


Fast path (pick your situation)#

You need to…

Do this first (safe default)

Then read

Use sensitive/clinical data without uploading it

Use local prepared exports + avoid Community Annotation + review figure metadata before sharing

Privacy model

Share sessions safely with a team

Treat .cellucid-session files like sensitive derived artifacts; avoid patient IDs in labels

Security, privacy, and trust

Make figures readable for colorblind audiences

Use perceptually-uniform colormaps; check the export preview’s colorblind simulation

Accessibility + Quality knobs and best practices
