LogN

Syncs the problems you solve on coding sites to your LogN dashboard, from the browser you are already logged in with.

LogN is a free tracker for DSA and competitive programming practice. It brings the problems you solve on different sites into one dashboard: totals, a heatmap, difficulty and topic breakdowns, weak-topic scores and "solve next" picks. Some sites don't share your full solved history publicly. This extension reads it in your own browser, where you are already logged in, and sends it to your LogN account. It syncs all our platform submissions and verifies or connects your Codeforces and AtCoder usernames. How it works • Click Connect in the popup and sign in to LogN. • Each site syncs once after you connect, then automatically while you browse it (at most every 6 hours; LeetCode once a day). You can turn automatic sync off in the popup, or click Sync at any time. • It only reads the sites you give it access to, and you can decline or withdraw access to any of them. • A platform you remove on LogN's Connect page stays removed. The extension won't add it back unless you click it. What it sends, and only to LogN: your username on each site, the problems you solved (ids, titles, links, difficulty, tags, solve dates) and solved and submission counts. It never sends passwords, cookies, your code, your email or your browsing history.
