Tools
The formula tools run in your browser. Values you type into them are not sent to our server and are not stored.
Contact form
If you use the contact form, we receive the name (optional), email address and message you enter, and the form records the time it was sent. We use them only to read and answer your message, and keep them no longer than needed for that. A short-lived record of your IP address is used to limit repeated submissions.
Server logs
Like most websites, our server keeps standard access logs (IP address, browser type, page requested, time) for security and to keep the site running. Logs are kept for a limited period.
Cookies and preferences
The site stores your light or dark theme choice in your browser’s local storage. It sets no tracking cookies of its own.
Analytics and advertising
We may use an analytics service to count visits and see which pages are useful, and we may show advertising from third-party ad networks. These services can set cookies or use similar technologies to measure visits and to show and measure ads, which may include personalised ads where the law allows. Where consent is required, you will be asked before these are used. This section will name each provider when it is in use.
