Dairy Ration Lab
Privacy
Last changed 28 October 2026
The Dairy Ration Lab is made by Dairy Data Science (Pádraig Lucey). Its accounts are agAI Inc.'s: you sign in with an agAI account. This page covers the hosted lab at lab.dairydatascience.com and its addresses for AI apps, lab.dairydatascience.com/mcp and mcp.dairydatascience.com.
Without an account
Your farms stay in your browser. To work out a ration, the page sends the farm to our server. The server keeps a copy for at most a day, so that each of its copies can answer, then deletes it.
With an account
We keep:
- your email address, and your name and picture if you sign in with Google;
- the farms you save: recipes and rations and their history, feeds, prices, lab tests, pens and cow numbers, and your own feed library.
They're kept so you can work on them from your phone, your computer and your AI app. Only you can see them. They're kept until you delete your account.
AI apps
When you connect an AI app (Claude or another) and allow it, it can read and change your farms, as the farm's next version, until you remove it. The lab gets only the tool calls the app makes: which farm, which recipe, the ration or file you asked about. It never sees or keeps your conversation. What you tell the app is under its maker's terms.
Who else is involved
- Supabase keeps accounts and farms for agAI, in Ohio, USA.
- Google Cloud runs the lab's server, in Oregon, USA. Google signs you in if you choose Google.
- Feed and milk prices come from USDA Market News. Weather for heat stress comes from the National Weather Service, Iowa State University's weather archive and NOAA, sent only the centre of the farm's ZIP code. None of them is sent anything about you.
Supabase and Google Cloud keep ordinary request logs (time, address, size), not what's in your farms. Google Cloud's are kept 30 days.
What we don't do
No advertising and no tracking. We don't sell or share your data, and your farms aren't used to train AI. Your sign-in is kept in your browser, not in a tracking cookie.
Deleting
Ask and we delete your account and everything in it. You can save any farm as a file first.
