TimeTwister Privacy Policy

Last updated: June 24, 2025

Overview

TimeTwister is designed with privacy as a core principle. We believe your data should stay yours.

Data We Handle

What We Store Locally

• Timezone preferences: For websites you configure (stored in Chrome's sync storage)
• Time format preference: Your choice between 12-hour and 24-hour display
• Favorite timezones: Timezones you star for quick access

What We Do NOT Do

• ❌ No external servers: All data stays in your browser
• ❌ No tracking: We don't track your browsing habits
• ❌ No analytics: No usage statistics collected
• ❌ No third-party sharing: Your data never leaves your control
• ❌ No personal information: We don't collect names, emails, or identifiers

How We Use Permissions

Storage Permission

• Purpose: Save your timezone preferences
• Scope: Only timezone settings you explicitly configure
• Location: Chrome's built-in sync storage (stays within Chrome ecosystem)

Tabs Permission

• Purpose: Detect which website you're on to apply the correct timezone
• Scope: Only reads the current tab's URL when you open the extension
• Usage: No browsing history tracking or monitoring

Debugger Permission

• Scope: Only activated when you set a timezone for a specific site
• Function: Temporarily overrides browser timezone for that tab only

Host Permissions

• Purpose: Apply timezone overrides to websites you configure

Data Synchronization

Your settings sync across your Chrome browsers using Chrome's built-in sync system. This happens entirely within Google's ecosystem - we never see or handle this data.

Data Security

• All data is stored locally in your Chrome browser
• Settings sync through Chrome's secure sync system
• No external transmission of personal data
• You can clear all data by removing the extension
