Privacy Policy

Last updated: January 13, 2026

1. Information We Collect

We collect information you provide directly to us, such as when you create an account, add immigration cases, participate in forums, or contact us for support.

  • Account Information: Email address, name, and password
  • Case Information: USCIS receipt numbers and case status data
  • Forum Content: Posts, comments, and interactions
  • Usage Data: How you interact with our services

2. How We Use Your Information

We use the information we collect to:

  • Provide, maintain, and improve our services
  • Track your immigration case status
  • Send you updates about your cases
  • Respond to your comments and questions
  • Analyze usage patterns to improve user experience

3. Information Sharing

We do not sell, trade, or rent your personal information to third parties. We may share information with your consent, to comply with legal obligations, or to protect the rights and safety of ImmiBook and our users.

We certify that:

  • We do not sell or transfer user data to third parties
  • We do not use data for purposes unrelated to immigration case tracking
  • We do not use data to determine creditworthiness or for lending

4. Data Security

We implement appropriate security measures to protect your personal information. All data is encrypted in transit using TLS and at rest using industry-standard encryption. However, no method of transmission over the Internet is 100% secure.

5. USCIS Case Data

When you add case receipt numbers, we check USCIS case status on your behalf. We store the case status information to show you history and send notifications. We are not affiliated with USCIS or the U.S. government.

6. Browser Extension

The ImmiBook USCIS Sync browser extension enhances our service by syncing detailed case data from your my.uscis.gov account.

Data Collected

When using the extension while logged into my.uscis.gov, we collect:

  • Case information (receipt numbers, types, form names, dates, statuses)
  • Applicant name associated with your cases
  • Case timeline and historical status updates
  • Document metadata (approval notices, receipt notices)
  • Your ImmiBook session token (stored locally only)

Extension Permissions

  • Storage: Save auth token and cache case data locally
  • Tabs: Detect when you're on my.uscis.gov
  • ActiveTab: Access case data when you initiate sync
  • Downloads: Download USCIS documents when requested
  • Cookies: Read my.uscis.gov session for authenticated requests
  • Scripting: Capture USCIS API responses for syncing
  • Host Access: Read USCIS case data from my.uscis.gov

Data Transmission & Storage

Case data is transmitted securely via HTTPS to ImmiBook servers. We do not transmit your USCIS login credentials—only case data visible in your account. The extension stores your ImmiBook auth token in Chrome's local storage, cleared when you log out or uninstall.

Data Deletion

  • Log out of extension — clears local authentication
  • Uninstall extension — removes all local extension data
  • Delete ImmiBook account — removes all synced data from servers

7. Your Rights

You have the right to:

  • Access your personal data
  • Correct inaccurate data
  • Delete your account and associated data
  • Export your data in a portable format

8. Cookies

We use essential cookies to maintain your session and preferences. We do not use third-party tracking cookies.

9. Changes to This Policy

We may update this privacy policy from time to time. We will notify you of any changes by posting the new policy on this page and updating the "Last updated" date.
