Privacy Policy

Overview

LinkGlow is committed to protecting your privacy. This policy explains how our browser extension and web application handle your data.

TL;DR: LinkGlow highlights links locally on your device. Sync is optional, and cloud AI is off until you explicitly enable it.

Browser Extension

Data We Don't Collect

• Browsing history
• Personal information (name, email, address)
• Passwords or authentication credentials
• Financial information
• Location data
• Cookies or tracking identifiers

Data Processed Locally

When you click "Analyze Page," the extension reads link elements on the current page to classify them as internal or external. This analysis happens entirely in your browser and is not sent to any server.

Optional Cloud AI

AI selector suggestions and AI link assessments are optional and disabled by default. If you opt in, LinkGlow sends a minimized summary of page structure plus the current page URL and title to our AI provider. We do not send the full page HTML for selector suggestions.

Data Stored Locally

• Settings: Your highlight colors, styles, and preferences
• Domain Groups: Custom domain classifications you create
• Audit Results: Link analysis results (stored in IndexedDB)

All this data is stored locally on your device using browser storage APIs.

Optional Cloud Sync

If you choose to sign in to LinkGlow, you can optionally sync your settings and audits across devices. This feature is entirely optional.

When Signed In, We Store:

• Your email address (for authentication)
• Your extension settings and preferences
• Domain groups you've created
• Link audit results you choose to sync

We Never Store:

• Your browsing history
• Full raw page HTML from extension AI selector requests
• Any data from pages you don't explicitly analyze

Web Application

The LinkGlow web application (linkglow.io) uses:

• Authentication: Email-based login via secure providers
• Database: PostgreSQL to store your synced data
• Hosting: Vercel (see their privacy policy)

Third-Party Services

We use the following third-party services:

• Vercel: Hosting and deployment
• Neon: Database hosting
• Anthropic: Optional AI selector suggestions and link assessments after user opt-in

We do not use any analytics, advertising, or tracking services.

Data Sharing

We do not sell, trade, or transfer your data to third parties. We do not use your data for advertising or marketing purposes.

Data Retention

Local data remains on your device until you clear it or uninstall the extension. Cloud-synced data is retained until you delete your account.

Your Rights

You can:

• Use the extension without creating an account
• Delete your local data at any time
• Request deletion of your cloud data by contacting us
• Export your data upon request

Changes to This Policy

We may update this policy occasionally. Significant changes will be communicated through the extension or website.
