Weekly off: Sunday always, and Saturday by default (toggle above). Saturdays stay tappable — when the office operates on a busy Saturday, stamp it WFO/WFH and it counts. Each stamp saves to this device instantly and syncs to the Tekfinotax server. Interns: open your personal link (from HR) to sync your own days without signing in — it works even if the page and API are on different domains. Export CSV hands the month off to HR.
