watches nobody.
Three plain facts
Nothing is kept,
because nothing
is taken.
These pages are plain files on a web server. Reading them leaves nothing behind on your machine and sends nothing about you anywhere.
No counting.
No visitor counter, no heat map, no advertising tag, no third-party script of any kind. We do not know how many people read this page, or which pages they read.
Nothing from elsewhere.
Every picture, font, stylesheet and script on these pages is served from this website itself. Your browser contacts no other company while a page loads.
The rest of it
What happens if
you write to us.
What happens to an email I send you?
It reaches the people who build Polycity and nobody else. We keep it while we are talking to you and for as long as we need it to answer, and we reply from the same address. Ask us to delete it and we will.
Do you pass anything to anyone else?
No. We sell nothing about you, share nothing with advertisers, and buy nothing about you from anybody. There is no mailing list on this website to be added to.
Does any link leave this website?
No. Every link on these pages opens another page of this website. The one exception is an email address, which opens your own mail program.
What about the Polycity product itself?
The product is a separate matter from this website, and a team that uses it gets its own terms in writing. Two things hold in every case. A team's city models, scenarios and runs stay inside that team's own organisation. And nothing about a named person goes into a model: the residents in a simulated day are invented from published population totals, never from anybody's phone, card or journey.
