Privacy policy

Short version: we do not collect, store or sell your personal information. What you type into our tools stays on your device.

Last updated 30 October 2026. Applies to this site and to each KayaWise site.

What we do not collect

Every calculator runs in your web browser. Your inputs are not sent to us or stored on our servers. We have no user accounts, sign-up forms or newsletters.

Links you share

Some tools add your inputs to the page address so the Share button can reproduce a calculation. This stays in your browser unless you choose to share or bookmark the link.

Analytics

On our kayawise.co.za addresses we use Cloudflare Web Analytics to see which pages and tools people use. It is cookieless: it sets no cookies, uses no browser storage and does not fingerprint or follow you across sites. It collects aggregate page views only (for example the page visited, the referring site, and the browser, device type and country), with no personal data, and nothing you type into a tool is sent. The small script is loaded from static.cloudflareinsights.com.

Hosting logs

Our hosting provider (Cloudflare) processes technical data such as IP addresses to deliver the sites and protect them from abuse. We do not use this data to identify you.

Advertising and cookies

We show ads from Google AdSense to keep the tools free. Google, as a third-party vendor, uses cookies and similar technologies to show ads, including personalised ads based on your visits to this and other websites, to limit how often you see an ad and to measure ad performance and detect fraud. Google's use of advertising cookies lets it and its partners serve ads to you based on your visits to our sites and other sites on the internet.

You can turn off personalised ads in Google's ad settings, and read how Google uses information from sites that use its services in How Google uses cookies in advertising. You can also block or delete cookies in your browser settings; the calculators keep working without them.

What you type into our tools is never sent to Google or to us. Under POPIA you may object to the use of cookies for direct marketing: opting out in Google's ad settings or blocking third-party cookies stops personalised ads.

Your rights under POPIA

The Protection of Personal Information Act gives you the right to know what personal information is held about you and to ask for it to be corrected or deleted. If you email us, we use your email only to reply. You may also complain to the Information Regulator (South Africa).
