Frequently Asked Questions
Are all tools really free?
Yes! Every tool on QuickToolKit is completely free to use. We keep the site running with minimal, non-intrusive advertising.
Do you store any of my data?
No. All tools run entirely in your browser. We don't send any data to our servers, and nothing you input is stored or logged.
Are the UK tax calculations up to date?
Yes. Our salary and tax calculators use HMRC's 2026/27 figures for the Personal Allowance, Income Tax bands, National Insurance and student loans, and the IRS 2026 federal brackets for US calculations. Each tax page links to its official sources.
Can I use these tools on mobile?
Absolutely. All tools are fully responsive and work great on smartphones and tablets.
