o90235.ingest.sentry.io: How Sentry Invades Your Privacy with Error Tracking

Sentry’s domain, o90235.ingest.sentry.io, is part of a system that collects error and performance data from apps and websites. While it’s marketed as a tool for developers to fix issues, it gathers intrusive details about your device and behavior. As Privacy Auditors, we’re here to expose what this tracker does and how it impacts you.

What Is o90235.ingest.sentry.io?

This domain belongs to Sentry, a service used by developers to monitor errors and performance issues in their applications. It captures a wide range of data whenever an app crashes or underperforms, often without your explicit knowledge or consent. This tracking compromises your privacy by logging technical and user-specific information.

Data It Collects

When you use an app or website integrated with Sentry, this domain grabs the following:

• IP Address: Identifies your network or approximate location.
• Error Stack Traces: Logs detailed crash reports, including code and variables.
• User Session Data: Tracks your actions with a unique identifier during app usage.
• Device Information: Captures hardware details like ‘iPhone 12’ or ‘desktop’.
• Operating System: Records specifics such as ‘Android 13’ or ‘Windows 11’.
• Browser Details: Notes your browser, like ‘Chrome 120.0’.
• Network Information: Logs connection type, such as Wi-Fi or 4G.
• Application Context: Gathers app version (e.g., ‘v2.3.1’) and environment data.
• Timestamps: Records exact times of events or errors.
• Custom Tags: Collects developer-defined data, which may include user IDs.
• Breadcrumb Data: Tracks actions like clicks or navigation leading to an error.

This data paints a detailed picture of your interactions, often tied to identifiable markers.

Who Gets Your Data?

Sentry shares your information with several entities:

• App Developer: The creator of the app or website using Sentry receives your error data.
• Cloud Provider: Companies like AWS or Google Cloud store and process this information.
• Third-Party Subcontractor: Business partners or service providers handle data for analytics.
• Law Enforcement Agency: Sentry complies with legal requests, potentially sharing your data under court orders.

How to Protect Yourself

At Privacy Auditors Institute, we’re dedicated to safeguarding your digital privacy. Here’s how to limit Sentry’s tracking:

• Block Trackers: Use tools like Privacy Auditor’s paid service to stop scripts from domains like o90235.ingest.sentry.io. Check browser extensions for tracker blocking.
• Use a VPN: Hide your IP address with a VPN like Mullvad to reduce location tracking.
• Choose Privacy Browsers: Opt for Firefox with strict protection or Tor Browser for anonymity.
• Limit App Permissions: Restrict app access to device data where possible in settings.
• Clear Data Regularly: Delete cookies and session data to disrupt tracking over time.

Combine these steps for stronger defense against invasive tracking.
