Self-service data export is not built yet. This page exists so the promise is documented, not so you can click a button and get a file today — if you try to export from inside the app right now, you won't find that option, because it isn't there.
Once shipped, data export will let you download your own farm data — properties, crops, livestock, inventory, equipment, expenses, and tasks — as CSV, with a PDF option for reports. It's tracked on our Roadmap as a near-term item.
Email support@farmos.app and we'll pull a copy of your records manually. It's your data — you're always entitled to it, export button or not. See our Privacy Policy for how we handle account data and deletion requests.
