3. Information We Collect & Storage Architecture
A. Offline-First Guest Mode (No Registration Required)
When you use DSA Tracker without creating an account:
- All problem completion checkboxes, bookmarked stars, and problem notes are stored exclusively in your browser's local storage (
localStorage).
- No progress or personal identifiers are sent to our backend servers.
- You retain 100% control over this data, which can be erased at any time by clearing your browser cache.
B. Cloud Sync Registered Account Data
If you choose to register for a free account to sync progress across multiple devices:
- Username & Credentials: We store your chosen alphanumeric username and a cryptographically hashed password (using industry-standard bcrypt with salt rounds). We never store plain-text passwords.
- Progress Data: Arrays of completed problem IDs, bookmarked problem IDs, problem note entries, and category expansion states.
- Authentication: Encrypted JSON Web Tokens (JWT) used solely for maintaining secure, authenticated sessions.
C. Log Files & Web Analytics
Like most modern web servers, DSA Tracker uses standard log files. The information inside log files includes Internet Protocol (IP) addresses, browser type, Internet Service Provider (ISP), date/time stamp, referring/exit pages, and number of clicks. This information is anonymized and used solely to analyze trends, administer the site, prevent denial-of-service attacks, and ensure platform performance.
