Privacy
Privacy, briefly
What this site collects, why, and how to switch it off.
The contact form
When you send a message, what you type (name, organisation, how to reply and the message) is emailed straight to me. It is not stored in a database, not shared with anyone, and used only to reply to you. You can ask me to delete your messages at any time.
Counting visits
The site uses Amplitude to see which pages and tools are read and used: visit counts, an approximate country and the type of device. It does not record your name or anything you type into a form. If your browser sends a Global Privacy Control signal, nothing is sent at all.
What stays in your browser
Your choice of suit (the colour theme) is saved in your own browser and never reaches me.
The tools in the lab
Everything you enter into the calculators and tools stays on your page and is gone when you close it. None of it is sent to a server.
