Analytics Data Collection

To improve our service and understand how our tools are used, we collect minimal, non-personal analytics data:

What We Collect:

Local Storage

We use your browser's localStorage only for:

• Remembering your theme preference (light/dark mode)
• Storing your consent acknowledgment

This data never leaves your device and can be cleared at any time through your browser settings.

How We Use Analytics Data

The minimal data we collect is used to:

• Understand which features are most valuable to users
• Identify and fix technical issues
• Optimize performance for different devices and browsers
• Plan improvements and new features
• Generate anonymous usage statistics

Data Sharing

We never sell or share any data with third parties for marketing purposes. The only data sharing that occurs:

• Anonymous analytics data may be aggregated for service improvement
• Technical data may be shared with our hosting provider (Vercel/Netlify) as part of standard web hosting

Third-Party Services

Express Lint is hosted on Vercel/Netlify for static file serving only. These services:

• Do not have access to any data you input into our tools
• Only serve the static HTML, CSS, and JavaScript files
• May collect basic access logs (IP addresses, browser info) as part of their standard operations
• Are bound by their own privacy policies

Your Rights

You have the right to:

• Opt-out: Use browser settings to block analytics or use private/incognito mode
• Clear data: Remove all locally stored preferences through browser settings
• Request information: Contact us about what data we have collected
• Data deletion: Request removal of any analytics data associated with your usage

Security

Since we don't collect or transmit your actual content, the primary security measure is that your data never leaves your device. For the minimal analytics data we do collect:

• All data transmission uses HTTPS encryption
• Analytics data is anonymized and aggregated
• No personal identifiers are stored
• Data is retained for a maximum of 2 years for trend analysis
