Private cronotype
Sign in with GitHub, compute a 90-day cronotype using commits your account can see, then keep the result only in this browser long enough to view or download it. GitHub's classic private repo scope is broad; Cronotype only makes read requests and does not save the token.
After you download the card, revoke the GitHub authorization from your GitHub settings.
Requests GitHub's classic private repo scope so commit search can include private repositories. Revoke access when you're done.
