Privacy

The short version: the calculators send nothing anywhere. The only data collected is an email address, if you choose to give one.

The calculators

Every calculator on this site runs entirely in your browser as JavaScript. The numbers you type are processed on your own device and are never transmitted, logged or stored on any server. Nobody — including the site owner — can see them. If you load a page and then disconnect from the internet, the tools continue to work, which is the simplest proof of the claim.

This includes the ABC–XYZ classifier, where you may paste a full SKU list. That data is parsed in memory in your browser and discarded when you close the tab.

Email addresses

If you submit the form to receive the free KPI starter pack, your email address is stored for the purpose of sending you that file and occasional notes about new tools or templates. It is not sold, rented or shared. Every email includes an unsubscribe link, and a request to be removed will be actioned.

Analytics and advertising

This site may use privacy-respecting analytics to count page views, and may display advertising served by Google AdSense. Advertising partners may set cookies and use identifiers to serve and measure ads, governed by their own privacy policies. You can control ad personalisation through Google's ad settings and through your browser's cookie controls. No information you enter into a calculator is available to any advertiser — it never leaves your device in the first place.

Local storage

The site may store small preferences — such as an email address you have already submitted — in your browser's local storage. This stays on your device and can be cleared through your browser settings at any time.

Children

This site is aimed at working professionals and is not directed at children.

Changes

If this policy changes, the updated version will be posted here.
