Ledsten sends nothing about you anywhere.

This website

• No cookies, no analytics, no tracking pixels and no advertising.
• Everything on these pages — text, styles, scripts and images — comes from this site. Nothing is loaded from other companies’ servers, so no one else learns that you visited.
• Nothing is stored in your browser.
• A small script on these pages checks what kind of device you’re using — a Mac, a Windows PC or a phone — so it can show the right button for it. That happens in your browser; the answer isn’t sent or kept anywhere.
• Like any website, the company that hosts it receives what every browser sends with each request — your IP address, the page asked for and your browser type — and may keep it in server logs for security. We don’t use those logs to follow or profile visitors. Hosting company and how long it keeps logs: to be added once hosting is set up.

The Ledsten app

• No account. There is nothing to sign up for, and the app never asks for an email address or a password.
• Your information stays on your computer. Household details, supplies, plans, paramedic handoff notes, the PDFs you add and your conversations with the assistant are saved in Ledsten’s own folder on your computer. Ledsten never sends any of it anywhere. It only leaves that folder if you take it out yourself: by printing, or by saving a phone copy — a plain file, not password-protected — to keep or to share by AirDrop, message or email.
• The assistant runs on your computer. Your questions and its answers never leave your machine.
• No tracking. No usage statistics, no crash reports and no advertising. The app does keep a count of how many times it has started, the date it was first opened, and how many outside requests it has blocked, and shows them to you on its Offline status screen; they never leave your computer.
• The one time it goes online is to download the assistant’s file, and only when you start it yourself: during setup, or later if you choose another version. The file comes from Hugging Face, a public site that hosts AI models. The request carries the app’s name and version and nothing else about you. As with any website, Hugging Face (and the network it serves files from) can see your IP address and that a download took place; its own privacy policy covers that. On a computer with no internet you can install the file from a USB stick instead: the download stops straight away and setup offers “Install from file…”. On a computer that’s online, setup starts the download first, so disconnect before that step if you want to skip it.
• It checks itself. The app’s window is locked so it can’t reach the internet, and a guard stops and counts anything that tries anyway. During setup’s Air-gap check it tries on purpose, three different ways, so you can watch each attempt being stopped; these test attempts aren’t counted. Afterwards the Offline status screen shows the count of anything blocked and this session’s log.

The waitlist

• If you ask to hear when Ledsten is ready, your email address goes to Buttondown, the service that keeps the list and sends the emails. It stores your address and when you signed up, and nothing else from this site.
• You’ll get an email asking you to confirm first. After that: one email when the first version is out, then only major releases.
• Opens and clicks are not tracked. Every email has an unsubscribe link, and you can ask us to delete your address at any time.

If this changes

If Ledsten ever collects anything, this page will say exactly what and why before it happens, with a new date at the top.
