Privacy Policy — H1B Checker for LinkedIn Jobs

Last updated: July 12, 2026

Overview

This policy describes how the H1B Checker for LinkedIn Jobs browser extension (“Extension”) handles information when you use it on LinkedIn job pages.

Information the Extension Accesses

The Extension runs only on LinkedIn URLs under https://www.linkedin.com/jobs/*. It reads company names from job listing elements that are already visible on your screen in the page DOM. It does not access your LinkedIn account settings, messages, feed, profile data, or credentials.

Information Sent to Our Servers

When you view a job listing, the Extension may send the visible company name (plain text) to our backend API over HTTPS:

• Endpoint: https://h1bchecker-production.up.railway.app (or as configured in the Extension)
• Purpose: To look up whether that employer appears in aggregated U.S. Department of Labor (DOL) H-1B LCA disclosure data and to return a yes/no style result for display on the page.

The Extension does not send your name, email, LinkedIn username, passwords, cookies, résumé, application history, or general browsing history.

Email Registration

The Extension offers a free preview. After the preview, continued use requires registering an email address. You may also optionally follow a company to be notified when its H-1B data updates — this stores your email together with the company name you chose to follow. In all cases the email is sent to our backend over HTTPS together with the Extension's random install identifier (see below), and is used only to send product and data updates about this Extension. We do not sell email addresses or share them with third parties. To have your email removed, contact us via the channel in the Contact section.

Anonymous Usage Statistics

To understand how many people the Extension helps, it generates a random identifier (a UUID) once when installed and includes it with lookup requests. This identifier is random, contains no personal information, is not linked to your LinkedIn account or identity, and is used only to count active installs and lookups in aggregate (for example, "how many installs were active this week"). You can reset it at any time by removing and reinstalling the Extension.

What We Do Not Do

• We do not sell your data to third parties.
• We do not use the Extension to build a cross-site tracking profile.
• We do not collect personally identifiable information beyond the email address you explicitly register.

Server-Side Processing and Logs

Our API and hosting provider (e.g., Railway) may create standard server logs (such as timestamps, IP addresses, and request paths) as part of normal HTTPS operations. Those logs are used for security, reliability, and abuse prevention, not for advertising. Retention depends on the hosting provider and our operational practices.

Data Source

Sponsorship-related statistics shown by the Extension are derived from public DOL LCA disclosure datasets that we aggregate into our database. The Extension does not scrape LinkedIn at scale or store LinkedIn page HTML on our servers.

Children

The Extension is not directed at children under 13, and we do not knowingly collect information from children.

Changes

We may update this policy from time to time. The “Last updated” date at the top will change when we do.
