About these tools

The ToolsPix Calculator Tools collection is designed to replace cluttered, ad-heavy calculator apps with fast, minimal web tools. Whether you're estimating a home loan, splitting a restaurant bill, or tracking your daily calories, these utilities give you instant answers without any bloat.

Every tool in this collection runs natively in your browser using pure JavaScript. This means calculations happen locally on your own CPU — ensuring your inputs are completely private and results appear with zero latency.

Common workflows

Personal Finance — use the Mortgage Calculator and Loan Calculator to estimate monthly payments and amortization schedules before making big decisions
Health Tracking — quickly check your BMI or find your baseline energy expenditure with the Calorie Calculator
Focus & Study — lock in for deep work sessions using the Pomodoro Timer and track your academic progress with the GPA Calculator
Shopping & Travel — verify sale prices with the Discount Calculator and check live exchange rates with the Currency Converter

Privacy by design

We believe that your financial plans and health metrics are your business. Unlike typical calculator apps that harvest usage data to serve targeted ads, ToolsPix is entirely tracking-free. There are no databases storing your mortgage rates or body weight. The tools simply calculate what you need and forget it the moment you close the tab.

FAQ

Are these calculators free to use?

Yes. Every tool in the Calculator collection is completely free. There are no usage limits, no premium versions, and you don't need to create an account.

Do you store my financial or health data?

No. All calculations are performed entirely in your browser using JavaScript. When you enter mortgage details, body weight, or student grades, that information never leaves your device and is never sent to our servers.

Can I use these tools offline?

Yes. Once the page has fully loaded in your tab, you can disconnect from the internet and the calculators (including the Pomodoro Timer and Scientific Calculator) will continue to work perfectly. The only exception is the Currency Converter, which requires an initial connection to fetch the latest rates.

Are the currency exchange rates accurate?

Our Currency Converter fetches the latest exchange rates from reliable financial APIs when you load the page, ensuring your conversions are as accurate as possible for everyday use.
