Methods and limits
Up to seven days elapsed and 1,000 laps. Uses performance.now monotonic timing rather than a drifting tick counter. The display shows hundredths; CSV retains rounded captured milliseconds. Browser precision and device sleep can affect measurements; this is not certified timing equipment. First-lap exclusion changes comparison statistics only. Undo restores the preceding lap boundary while total elapsed time continues. Pause before Reset or exporting a consistent report. Reload clears the stopwatch.
Private processing
Entries, names, booking references, notes and timer state stay in browser memory. No uploads, account connections, external model calls or automatic storage. Refreshing clears the workspace; explicitly save a draft or export to keep your work. Downloaded reports contain entered information. No messages are sent to clients, colleagues or travel providers.
