Overview

Sightline is a browser extension that helps developers inspect spacing, typography, colors, layouts, and CSS rules directly on webpages.We believe privacy should be simple. Sightline operates locally in your browser and is designed to minimize data collection.

Information We Access

To provide inspection and debugging features, Sightline may access webpage content currently visible in the active browser tab.This may include HTML elements, CSS styles, typography information, colors, spacing values, and layout data.This access is required for Guide Lines, Box Model Inspector, Typography Inspector, Color Inspector, and CSS Cascade Debugger functionality.

Information We Store

Sightline stores settings locally using browser storage.Examples include guide positions, preferences, and extension configuration settings.This data remains on your device and is not transmitted to external servers.

Information We Do Not Collect

Sightline does not collect personal information, browsing history, authentication credentials, financial information, personal communications, or health information.We do not build user profiles and we do not sell user data.

Data Sharing

Sightline does not sell, rent, or share user data with third parties.Webpage content, inspection results, and browser activity are not transmitted to our servers.

Analytics

Sightline does not track which websites you visit or which elements you inspect.If optional analytics are introduced in the future, this policy will be updated accordingly.

Security
