CPJournal Importer

Automatically detect and import your competitive-programming submissions into CPJournal.

CPJournal Importer automatically detects competitive-programming submission results on supported Codeforces, AtCoder, CodeChef, LeetCode, and USACO pages and imports normalized progress into the user's private CPJournal account at dataol.net. When available, it verifies the logged-in contest-site identity before associating submissions with an account. It normalizes contest, problem, submission, verdict, timestamp, and detailed result data, and it also supports a user-initiated import from the extension popup. The extension does not upload cookies, passwords, session tokens, source code, raw HTML, or problem statements. It stores its CPJournal configuration, bearer token, installation identifier, queued normalized imports, and queued diagnostic events locally so failed deliveries can be retried. Diagnostic events are sent to CPJournal for troubleshooting and do not contain raw page content.
