📋 When to Use the Temperature Tracker
The Temperature Tracker is a handy tool for everyday tasks — whether you're troubleshooting a technical issue, checking something quickly, or solving a one-off problem. Use it when you need a reliable utility without searching through app stores or signing up for services. It's built for anyone who values convenience, privacy, and instant access — from IT professionals to casual users who just want things to work.
⚙️ How the Temperature Tracker Works
The Temperature Tracker is a client-side utility that processes your input directly in the browser. When you interact with the tool, JavaScript functions handle the logic — parsing, computing, transforming — and update the page in real time. The tool stores your temperature readings in browser localStorage. All processing is stateless and local; your data is never stored or sent to any external server.
How to Use the Temperature Tracker
- Enter a reading — Type your temperature in °C and an optional note (e.g., "Morning check"). Hit Enter or click Add Reading.
- Monitor your stats — View your average, max, and min temperatures at a glance. The stats panel updates automatically.
- Watch the chart — Your temperature trend appears as a line graph. A red dashed line marks the 38°C fever threshold.
- Export your data — Download your readings as CSV for spreadsheets or JSON for apps. Useful for sharing with healthcare providers.
Frequently Asked Questions
Is my health data private?
Yes. All temperature data is stored only in your browser's local storage. Nothing is sent to any server. Clear your browser data to erase all readings.
Can I use Fahrenheit instead?
Currently the tracker uses Celsius. You can convert Fahrenheit readings before entering them (subtract 32, multiply by 5/9).
How many readings can I store?
The tracker keeps the most recent 100 readings. Older entries are automatically removed to save space.
What's considered a fever?
The tracker flags temperatures above 38°C (100.4°F) with a red alert. Temperatures between 37.5-38°C show a warning. This is for reference only — consult a healthcare professional for medical advice.
