Your prompts don't leave your machine.
burnlog is a leaderboard for how many tokens you burn through AI coding agents. It is not an analytics tool for what you build with them.
What the CLI reads
The burnlog CLI reads local log files written by your coding agents — e.g. ~/.claude/projects/*/*.jsonl for Claude Code, ~/.codex/sessions/**/*.jsonl for OpenAI Codex. These files contain token usage alongside prompts, tool calls, and file contents.
The CLI extracts only the token-usage numbers and a random request id (for dedup). Everything else — prompt text, filenames, working directory, session ids, tool output — is discarded locally and never transmitted.
What the server stores
Per burn event, we store exactly these fields:
requestId— a random opaque id used only to detect duplicate uploads.source— which CLI (claude-code,codex, …).model,provider— e.g.claude-opus-4-7,anthropic.inputTokens,outputTokens,cacheCreationTokens,cacheReadTokens,totalTokens.timestamp— when the model call happened.
We do not store: prompts, responses, file paths, project or repo names, working directory, session ids, tool outputs, or any content produced during your agent session.
The source-of-truth is the Prisma schema at web/prisma/schema.prisma in the public repo. If you can read it, you can audit it.
Account data
Signing in uses GitHub OAuth. We receive your GitHub username, display name, avatar URL, email (if public), and bio. We use these to show your profile on the leaderboard. You can delete your account at any time from settings; this cascades and permanently removes every burn event we've recorded for you.
Cookies & analytics
We set a session cookie to keep you logged in. We don't run third-party analytics, pixels, or ad trackers. If we add a self-hosted analytics tool in the future, we'll list it here before turning it on.
Self-hosting
burnlog is open source (MIT). You can self-host the entire stack — web + Postgres — and keep the data on your own machine. Point the CLI at your instance with BURNLOG_API_URL.
