Open toolFrequently asked questions
Is GO Tools really free to use?
Yes. Every calculator and utility on GO Tools is completely free, with no sign-up, no paywalls and no hidden limits.
Do I need an internet connection?
No. GO Tools is installable as a Progressive Web App (PWA), so once you've visited it once, the calculators keep working even when you're offline. Only the Currency Converter needs a connection to fetch the latest live rates — it falls back to recent cached rates automatically.
Is my data stored or shared anywhere?
No. All calculations run directly in your browser. Countdown timers are saved only on your own device using local storage, and nothing is ever sent to a server.
Can I install GO Tools on my phone?
Yes. On most mobile browsers you'll see an "Install" prompt, or you can use your browser's "Add to Home Screen" option to use GO Tools like a native app.
