Privacy

Short version

This is a static website. There are no accounts, no user tracking, no advertising or analytics code, and we collect no personal information.

What we do not collect

• There is no registration, login or account system, so there are no names, email addresses or phone numbers.
• No analytics tools, advertising pixels or third-party tracking scripts are installed.
• No cookies are used to identify or track visitors.
• Anything you type or tick on a tool page is processed entirely in your browser, is never sent to a server, and is not stored. Refreshing clears it.

What is technically unavoidable

To deliver pages to you, the server and content delivery network hosting this site may, as is standard, produce access logs containing an IP address, a timestamp, the page requested and a browser identifier. Those logs are handled by the providers under their own policies for operations and security, and we do not use them for profiling or personalisation.

External resources

This site uses two categories of external resource:

• Web fonts — pages load font files from a third-party font service, so your browser makes a request to that service.
• Market data — only the volatility gauge makes a single request to an exchange's public market data endpoint when it opens. That request carries no personal information and needs no account. No other page makes such a request.

Once you follow an external link, you are covered by that site's privacy policy rather than anything here.

Your rights

Because we do not hold your personal data, there is usually nothing to access, correct or delete. If you believe this site holds information relating to you, raise it through the contact page and we will look into it.

Children

This site is intended for adults, is not directed at minors, and does not knowingly collect information from them.

Changes

If we introduce anything that changes the above, this page will be updated and the change recorded on the corrections page.
