Geld collects nothing: no analytics, no telemetry, no accounts, no server. It runs only on GitHub hosts and reads the page you are already looking at. When a page has no per-file diffs it fetches the pull request's .diff from GitHub, exactly as if you had added ".diff" to the URL. Settings live in your browser's sync storage. Optionally, sign in with GitHub (gist scope only) to sync settings through a secret gist on your own account; the token never leaves your device except to talk to GitHub.
