Privacy
The short version: the calculators run in your browser and no trade data is stored.
Calculators
Everything you type into a calculator stays on your device. It isn’t sent to us or to anyone else, and it isn’t saved. Refreshing or closing the page clears it.
Premium waitlist
The waitlist is the only part of the site that sends information. If you join, your email address is stored with our email service, Brevo, and we use it only to tell you about Premium. Every email includes an unsubscribe link, and unsubscribing removes you from future emails.
Contact
If you email us, we use your message and address only to reply. To have your details removed, email the address on the contact page.
Hosting and visitor numbers
Like any website, this one runs on a hosting provider that may keep basic technical logs, such as IP addresses, to run and protect the service. We may also use visitor statistics that count page views. Those never include what you type into a calculator.
Cookies
The site doesn’t set its own cookies.
Ads and affiliate links
There are no ads or affiliate links on the site today. If that changes, this page will be updated first and any paid link will be labeled next to the link.
