Sentry’s tracker, browser.sentry-cdn.com, is built to monitor errors on websites, capturing detailed data about your interactions. Marketed as a debugging tool, it invades your privacy by logging sensitive information. Here’s what you need to know and how to protect yourself.

What Is browser.sentry-cdn.com?

This domain is part of Sentry, a platform for error tracking used by developers. It collects data on crashes and user behavior to pinpoint issues. As Privacy Auditors, we warn that this tracking exposes personal details without your clear consent.

Data It Collects

When you visit a site with Sentry, it logs:

• IP Address: Reveals your location, tied to your home or office.
• User-Agent: Notes your browser and OS, like ‘Safari 17.0 on macOS’.
• JavaScript Errors: Captures crash details with full error logs.
• Session ID: Links your actions with a unique identifier.
• Page URL: Records the exact page, including search parameters.
• Timestamps: Tracks every event with second-by-second precision.
• Referrer URL: Logs where you came from, like an ad or link.
• Device Type: Detects your device, such as ‘iPhone 14 Pro’.

This data creates a traceable footprint of your online activity.

Who Gets Your Data?

Sentry shares your information with:

• Website Owner: The site using Sentry accesses your error and behavior data.
• Cloud Hosting Provider: Companies like Google Cloud store your data.
• Third-Party Analytics Partner: Subcontractors process your information.
• Government Authority: Sentry complies with legal demands, potentially handing over your IP or session data.

How to Protect Yourself

Privacy Auditors are here to help you regain control over your data. Here’s how to block Sentry’s tracking:

• Install Tracker Blockers: Use extensions or Privacy Auditor’s service to halt scripts from this domain.
• Use a VPN: Hide your IP with a tool like Mullvad to avoid location tracking.
• Opt for Privacy Browsers: Choose Firefox with strict protections or Tor for anonymity.
• Turn Off JavaScript: Disable JavaScript to stop tracking, though some sites may not work.
• Wipe Cookies: Clear cookies regularly to break session tracking.

Layer these defenses to minimize exposure to trackers like Sentry.
