Privacy policy

This site collects as little as it can get away with. This page says exactly what that is.

What is collected

• Nothing, to read a lesson. No account is required and no tracking cookie is set for reading.
• What you type into a form. Name, email address, topic and message, when you use the contact or waitlist form.
• A session cookie, strictly to protect forms against cross-site request forgery. It expires when you close the browser.
• Standard server logs kept by the hosting provider — IP address, time, page requested, browser string — used for security and troubleshooting.

What the calculators do

The tools on this site run entirely in your browser. The figures you enter are never transmitted to the server, never stored, and never seen by anyone.

How form data is used

To reply to you, and to contact you about a cohort if you asked to be on the waitlist. It is not sold, rented or shared for marketing. It is deleted when it is no longer needed for that purpose.

Third parties

Fonts are loaded from Google Fonts, which means your browser makes a request to Google's servers and Google may log the IP address of that request. No analytics or advertising trackers are installed. If payment processing is added for the cohort, the processor's own privacy policy will apply to the payment data and will be linked at the point of payment.

Your rights

Write to support@chartkunji.com to ask what is held about you, to correct it, or to have it deleted. Requests are answered within thirty days.

Children

This site is not directed at anyone under 18 and no account or data is knowingly collected from a minor.

Changes

If this policy changes, the date at the top of this page changes with it.
