CodeClimax Privacy Policy

Last Updated: November 17, 2025

Overview

CodeClimax is a browser extension that enhances your LeetCode experience by displaying celebration media when you successfully solve programming problems. This privacy policy explains how we handle your data.

Data Collection

What We Collect

Local Storage Only:

  • Extension settings and preferences (enabled/disabled status, selected media)
  • User-provided celebration media URLs (YouTube, Giphy, Tenor, Vimeo, direct image/video links)
  • Media metadata (titles, thumbnails, timestamps) for organizing your celebrations
  • Temporary cache data for improved performance

What We DON'T Collect:

  • Personally identifiable information (name, email, address, etc.)
  • Account credentials or passwords
  • Financial information
  • Location data
  • Browsing history
  • Personal communications
  • Health information
  • Authentication tokens

How We Collect Data

We collect data only when you:

  • Add celebration media URLs to your collection
  • Change extension settings
  • The extension detects a successful LeetCode submission (DOM observation only)

Data Usage

How Your Data Is Used

  • Display Celebrations: Show your selected celebration media when you solve LeetCode problems
  • Manage Collection: Organize and store your personal celebration media library
  • Extension Settings: Remember your preferences for future sessions
  • Performance: Cache media metadata to reduce loading times

What We Don't Do With Your Data

  • We do not sell your data to third parties
  • We do not share your data with advertisers
  • We do not use your data for profiling or analytics
  • We do not transmit your data to external servers (except for media embedding)

Data Storage

Local Storage

All your data is stored locally in your browser using chrome.storage.local:

  • Maximum Storage: 10MB per browser profile
  • Data Type: JSON format containing settings and media metadata
  • Location: Browser's local storage (not accessible to websites)

Media URLs

When you add media URLs:

  • The URLs and associated metadata are stored locally
  • The extension validates URLs by making temporary HTTP requests to fetch metadata
  • Actual media files are not downloaded or stored by the extension
  • Media is displayed using iframes or img elements pointing to the original sources

Data Security

Security Measures

  • All data remains on your local device
  • No data is transmitted to CodeClimax servers
  • Extension permissions are limited to necessary functionality
  • Media URLs are validated before storage

External Services

When using media from external platforms:

  • YouTube: Videos are embedded using YouTube's iframe player
  • Giphy: GIFs are displayed using direct image URLs
  • Tenor: GIFs are displayed using direct image URLs
  • Vimeo: Videos are embedded using Vimeo's iframe player

These services have their own privacy policies. CodeClimax does not collect or share data with these services beyond what's necessary for media embedding.

Third-Party Services

LeetCode Integration

  • Purpose: Detect successful problem submissions
  • Data Access: DOM observation of success indicators only
  • Scope: Only on leetcode.com problem pages
