Privacy Policy

Horizon Tab ("we", "our", or "the extension") is committed to protecting your privacy. This policy explains how we collect, use, and protect your information when you use our Chrome extension.

Local Storage (No Account Required)

The following data is stored locally on your device and never leaves your computer unless you choose to sign in:

• Weather preferences: Your chosen location (city, coordinates) and whether you use automatic location detection
• UI settings: Clock format (12h/24h), temperature unit, display preferences
• Favorite wallpapers: URLs and metadata of images you've favorited (cached locally)
• Todo items & Notes: Your tasks and notes (stored locally unless synced)

This data is stored in your browser's local storage and is never transmitted to our servers unless you sign in.

Cloud Storage (Optional - When Signed In)

If you choose to sign in with your Google account, we store the following in Firebase (Google's cloud database):

• Account information: Email address, display name, and profile photo from your Google account
• Synced preferences: Weather settings, UI preferences
• Favorite wallpapers: Your saved wallpaper collection (up to 9 wallpapers)
