ShipCheck Privacy Policy

Last updated: September 3, 2026

ShipCheck is a Chrome extension that helps frontend teams identify release regressions by running user-initiated checks on the currently active web page.

Data Collection

ShipCheck does not collect, transmit, sell, or share user data with the developer or third parties.

ShipCheck does not require a user account and does not use analytics, advertising trackers, or telemetry.

How ShipCheck Works

When the user explicitly starts a scan, ShipCheck temporarily accesses the active web page to perform frontend quality checks, including:

• Runtime error checks
• Network request checks
• Responsive layout checks
• Automated accessibility checks
• Performance checks

This processing occurs locally within the user’s browser.

ShipCheck may process technical information required to perform these checks, such as page URLs, resource URLs, runtime errors, network status information, DOM-related selectors, accessibility findings, and performance measurements.

This information is used only to provide ShipCheck’s frontend release-checking functionality.

Local Storage

ShipCheck uses Chrome’s local extension storage to store information such as saved baselines and scan-related state.

Saved baselines allow ShipCheck to compare a current scan with a previous baseline and classify findings as NEW, EXISTING, or FIXED.

This information remains locally in the user’s browser and is not transmitted to the developer or to a ShipCheck server.

Users can delete saved baselines through the extension.

Sensitive Information

ShipCheck is not designed to collect personal, authentication, financial, health, or other sensitive user information.

Where technical values are used to generate finding fingerprints, known sensitive and volatile patterns are sanitized before hashing.

ShipCheck does not intentionally include sensitive query values in its fingerprints.

Remote Code

ShipCheck does not execute remotely hosted code.

The code required to perform ShipCheck scans, including its accessibility checking library, is packaged with the extension.

Data Sharing and Selling

ShipCheck does not sell user data.

ShipCheck does not transfer user data to third parties.

ShipCheck does not use user data for advertising, creditworthiness, lending, or purposes unrelated to its frontend release-checking functionality.

Permissions

ShipCheck requests only the Chrome permissions required for its functionality:

• activeTab — provides temporary access to the active page after the user invokes ShipCheck.
• scripting — allows ShipCheck’s packaged scanning code to run on the active page.
• sidePanel — displays ShipCheck’s interface, findings, and release verdict.
• storage — stores baselines and scan-related state locally in the browser.

ShipCheck does not request persistent access to all websites.

Changes to This Privacy Policy

This Privacy Policy may be updated if ShipCheck’s functionality or data practices change. The latest version will be published on this page.
