Privacy
terra.pura is a student project for the NASA Space Apps Challenge 2026. We keep what you give us only so the site can work for you, and we do nothing else with it.
- Your data is just stored. We don't sell it, share it, analyse it, advertise with it or train anything on it.
- No accounts are needed. Without one, everything stays in your own browser.
- No tracking, analytics or advertising cookies.
- Deleting your account deletes everything we hold about you, straight away.
What stays in your browser
The land you draw, your providers, machinery, wages and the analysis are saved in your browser's local storage so the dashboard works when you come back. We can't see this. Clear it any time with Settings → Start over, or by clearing your browser data.
If you make an account
- Username and password. Your password is stored only as a scrypt hash, so nobody (including us) can read it. We don't ask for an email address or your real name.
- Farms you choose to save (up to 5): the same farm details as above, stored so you can open them on another device.
- One sign-in cookie (
tp_session) that keeps you signed in for 30 days. It's removed when you sign out. - The server briefly keeps your IP address in memory to block password guessing (cleared within 15 minutes), plus standard web server logs.
It's kept on the terra.pura server and used only to show your farms back to you. Rename or delete farms on your account page; "Delete my account" removes your account and every saved farm permanently.
Automatic connection verification (VPN check)
terra.pura is hosted by Sorila, and this check applies across all Sorila sites. As soon as you visit, our servers temporarily process your IP address to check if you are using a VPN (Virtual Private Network), which are prohibited for safety. This specific IP check is completely automated; no human sees this data, your location is not resolved, and the IP is only held for a few seconds to match against VPN databases before being discarded. It is not permanently stored in our active administration logs. See the Sorila privacy policy.
Data services the site talks to
To analyse your land, your browser sends your field's coordinates (not your name or account) to public data services: NASA POWER, NASA GIBS and EONET, ISRIC SoilGrids, Open-Meteo, OpenStreetMap (Nominatim and Overpass), and in some countries postcodes.io, Octopus Energy, Red Eléctrica, the US PNNL and EPA map services and exchange-rate data. Map and satellite images load from OpenStreetMap, Esri and NASA. Each of those services has its own privacy policy. The full list is on the About page.
