NetPayHub
How we protect your data
Most "free" salary tools quietly send what you type to their servers or to advertising and analytics partners. NetPayHub is built the opposite way: the maths happens on your device, and the page is technically prevented from sending your numbers anywhere.
Where do the calculations happen?
100% in your browser. The tax logic is plain JavaScript that runs locally on your computer or phone. When you change a figure, your device does the arithmetic instantly — there is no round-trip to a server, because there is no server doing calculations at all.
Is any of my data sent over the internet?
No. Each page sets a Content-Security-Policy with connect-src 'none' and
form-action 'none'. In plain terms, the browser itself blocks the page from making
any outbound network request — no fetch, no background calls, no form submissions.
Even if a bug tried to send your salary somewhere, the browser would refuse.
What is stored or remembered about me?
Nothing about your inputs. We don't use cookies for your figures, we don't write your salary to local storage, and there are no accounts and no database. Close or refresh the tab and every number you entered is gone for good.
connect-src 'none' blocks the page from sending data out.How are PDF reports generated?
Locally, using your browser's own print-to-PDF feature. We don't load any external PDF library, so producing a report doesn't send your figures anywhere either — the document is built from what's already on your screen.
What security headers does the site use?
Beyond the strict Content-Security-Policy, every response is served with HSTS,
X-Content-Type-Options: nosniff, X-Frame-Options: DENY,
Referrer-Policy: no-referrer and a restrictive Permissions-Policy. Together these
reduce the ways your visit could be intercepted, framed or leaked.
Frequently asked questions
Does NetPayHub store my salary or income?
No. Your figures live only in your browser's memory while you use the calculator. Nothing is written to a cookie, to local storage or to any database, and refreshing the page clears it.
Is my data sent to a server?
No. Every calculation runs locally, and a Content-Security-Policy with connect-src 'none'
blocks the page from making any outbound request. Your numbers cannot leave your device.
Are there any trackers or ads reading my inputs?
No. The calculators load no analytics, no tag managers and no third-party advertising scripts. There is nothing on the page that can read what you type.
If you add ads later, will that change?
Privacy comes first. Any future advertising would be isolated from the calculator and would never be allowed to read your inputs, with proper consent where required.
