Data and sources

• Knowledge modules run by the same administrator: Moja Pasza (mojapasza.com), Moja Serowarnia (mojaserowarnia.pl) and Targ Rolny (targrolny.com). The hub forwards a tool call to the module server and returns its answer with the source added.
• Farm prices from the Polish Ministry of Agriculture (ZSRIR), Statistics Poland (GUS) and the World Bank, always with the period and a link to the source.
• Knowledge data is CC BY 4.0. Shop prices and offers are not: they are shown with the date checked and a link to the offer. Nutrition standards are cited with their source.
• The order of farms and shops depends only on distance and match. No one can pay for a position. There is no sponsored content.

Privacy (summary)

The full policy, in Polish, is at danerolne.com/prywatnosc and is the binding version.

• What we collect: daily totals only: which tool was called, the type of assistant (for example Claude or ChatGPT), whether it was a test, which catalog entry was shown, the topic from a fixed list and the area (municipality or region), and the ?z= tag from the connector URL. We do not store the text of questions, conversations or IP addresses. Clicks on links from answers (danerolne.com/idz/…) add to a daily total per entry, without IP or browser data.
• Use and storage: to see which tools are used and what is missing in rural areas. Stored in Supabase (EU, Frankfurt); servers and mail run on Cloudflare.
• Sharing: the hub forwards the tool call itself (what the assistant asks) to the module server that answers it. It does not forward the IP address. We do not sell or share data with anyone else.
• Owner login: farm owners can log in (danerolne.com/zaloguj) to edit their page on Targ Rolny. Only after they click “Zaloguj” do we set one login cookie (dr_sesja, 30 days). The other service receives a one-time code (5 minutes) naming the entry, never the e-mail address.
• Retention: daily totals have no personal data and are kept without a time limit. Bot visits: 12 months. Cloudflare technical logs (with IP): a few days. Database backups: about three months.
• Contact: data administrator Marek Walczak, Gietrzwałd, Poland, kontakt@danerolne.com. We answer within one month.
