In short
The site doesn't use your browser's local storage for anything today.
This site does not currently store anything in your browser's local storage. If that changes, for a feature like a saved preference, it will only ever hold a value that stays on your device and is never sent to any server, and this section will be updated to describe exactly what and why before that ships.

In short
Share links carry your network settings, not your identity.
When you use a "Share this setup" link, the dataset, activation function, and network shape you chose are encoded directly into the URL as query parameters, for example, ?dataset=spiral&layers=4-4. That URL only contains the configuration you set; it doesn't identify you, and it's only shared with people you choose to send the link to.
04
In short
The host keeps ordinary technical logs, like every website does. Nothing is sold or profiled.
Like virtually every website, our hosting provider may collect standard technical logs (such as IP address, browser type, and request timestamps) for security and reliability purposes. We don't separately access, sell, or build profiles from this data.
05
In short
There are none today. If that changes, this page changes first, and the diff is public.
At the time of writing, this site runs no analytics or tracking scripts of any kind - no Google Analytics, no ad pixels, no session recording. If that ever changes (for example, to add privacy-respecting, non-personal aggregate analytics), this page will be updated first and the change will be visible in the site's public source history, since the whole project's source is publicly available.
