Measure elapsed time with pause/resume, lap splits and downloadable session reports.
Keep this page open. Closing or switching tools ends this session; it is not saved. Background sleep can delay feedback.
All inputs stay in this page. No uploads or application history. Input edits invalidate generated outputs. Numeric quick sliders never clamp wider exact fields. Elapsed wall-clock stopwatch with pause/resume and up to 1,000 lap records. Displayed milliseconds are not a measurement-accuracy guarantee. Device clock changes affect timing; backward clock deltas clamp to zero. Maximum 9,999 hours. No application history: switching/closing/reset releases the session. Export a snapshot report to keep laps.
Ready. Start when you choose.

Your dates, clock settings and calendar labels stay on your device. Self-hosted browser code processes the inputs without uploads, accounts or application history. Browser time-zone rules and your device clock are used without remote lookup.

No. Timers/clocks run only in the active browser page or workspace panel. Closing, Reset or switching tools releases that session. Background throttling and device sleep can delay feedback, and device-clock adjustments affect wall-clock timers. No notification permission, service worker or server alarm is used.
No. Weekend/holiday rules are supplied by you; no regional legal calendar is inferred. Time-zone calculations use the browser’s installed rules. The Meeting planner rejects skipped local times and requires an explicit occurrence for repeated times.
No application input history is stored. Reports/downloads and explicit clipboard copies exist outside the tool when you request them. Clear, Reset, workflow switching and page exit release current application data; this is not a physical memory-erasure guarantee.
