このツールについて
Period Tracker is a free, browser-based tool that lets you calculate health metrics instantly — without installing software, signing up, or uploading files to any server. Everything happens locally in your browser, so your data stays on your device.
This tool is built for everyday use: from quick one-off tasks to repeated workflows. It loads in milliseconds, works offline once cached, and runs equally well on desktop, tablet, and mobile. The interface is deliberately minimal so you can focus on the result rather than learning the tool.
Common use cases include: tracking fitness, nutrition or wellness goals; quick checks before deciding on a workout or meal plan; supporting conversations with your doctor or trainer; building habits with timers and trackers. Whether you're a student, a professional, or just need a quick utility, Period Tracker gets the job done in seconds.
Privacy is built in by design. Because all processing happens client-side in your browser, no analytics service, advertising network, or backend ever sees your input or output. You can verify this by checking your browser's network tab while using the tool — you'll see zero outbound requests for your data. That makes Period Tracker suitable for sensitive content (medical, legal, financial) where uploading to a third-party service would be a non-starter.
Period Tracker is part of ToolHub — a free, ad-free, open-access collection of 750+ in-browser utilities covering PDFs, images, text, calculators, developer tools, design, social media, education, business, health, and more.
