Privacy
Your times stay on your device
Laps, sessions, personal bests, study logs and settings are saved in your browser's local storage on this device so they survive a reload. They're never sent to us. Clearing your browser's data for this site deletes them.
Usage measurement
On stopwatch.ca we use Google Analytics to count page views and which tools are used — for example that a lap was recorded, never the time itself or anything you type. Google signals and ad personalisation are switched off. If your browser sends Global Privacy Control or Do Not Track, no analytics load at all.
Links to shops
The buying guide links to Amazon.ca. If a link carries an affiliate tag, we say so on that page; Amazon then handles your visit under its own privacy policy.
