Privacy Policy

Short version: the calculators run entirely in your browser. We don't see, store, or upload the numbers or files you put into them.

What we collect

Tool inputs: nothing. All calculations happen locally in your browser (client-side JavaScript and WebAssembly). The salaries, tips, images, and other inputs you enter are never transmitted to us or any third party.

Local storage: some tools save your last inputs in your browser's localStorage purely so a refresh doesn't lose your work. This data stays on your device and you can clear it anytime via your browser settings.

Usage analytics: aggregate, anonymised usage via Google Analytics 4 — page views, referrer, approximate region (derived from your IP, which Google truncates) and device/browser type. This never includes the inputs you type into a tool, and we do not try to identify you.

Third-party resources our pages load

Google Analytics (gtag.js) — every page loads Google’s analytics script from googletagmanager.com to measure aggregate traffic (page views, referrer, approximate region, device and browser type). It never receives the values you enter into a tool. Google processes this data under its own privacy policy.
esm.sh — the JPEG XL converter dynamically loads a WebAssembly module from this CDN on first use. Your image is still decoded locally; only the code module is fetched. No other page makes this request.

Fonts and styles are self-hosted — the site makes no requests to Google Fonts or any styling CDN.

Cookies

We use Google Analytics 4, which sets first-party Google Analytics cookies (such as _ga) to count visits and distinguish sessions. We do not use advertising, ad-retargeting, or cross-site tracking cookies, and analytics never records the values you type into a tool. You can block these cookies with your browser or an extension without affecting any calculator.

Your rights

Because we don't collect personal data, there's nothing for us to access, export, or delete on your behalf. Data saved by a tool lives only in your browser.
