Independently Verified Security

Visual Inbox has passed the Cloud Application Security Assessment (CASA) Tier 2, an independent security review program managed by the App Defense Alliance. Here's what that means for you:

Third-party audited Security controls reviewed by an independent assessor, not just self-reported.
Your data stays local Verified that your emails, calendar, and messages are processed only in your browser.
Hardened against attacks Tested for OWASP Top 10 vulnerabilities including XSS, injection, and broken authentication.
Transparent practices Published security docs, incident response plan, and vulnerability disclosure policy.

How It Works

Three steps. Your data never leaves your browser.

1

You connect

Sign in with Google OAuth or upload a Slack ZIP. We request only metadata — never message bodies.

2

Your browser does the work

All data processing and visualization happens locally in your browser. Nothing is sent to our servers.

3

You see your network

Explore interactive visualizations of your communication patterns. Delete your data anytime with one click.

Visual Inbox serves only static code (HTML, CSS, JS) — there is no backend and no database. Your browser talks directly to Google's APIs. Your personal data never touches our servers.
