2. What we collect

When you register an account, we store:

• Email address — for account verification, login, and service-related communications
• Username — publicly visible display name
• Password — stored exclusively as a cryptographic hash; we never have access to your plaintext password

When you use the service, we additionally store:

• Watchlist entries and Price Alerts — the items, thresholds, and preferences you configure
• Session data — a session cookie to keep you logged in (see Section 6)

Our server automatically collects access logs containing your IP address, browser type, referring page, and timestamp. These logs are used solely for security and error diagnosis and are deleted after 14 days.
