How we work with public data
- Only official open-data portals and public pages whose terms allow automated access.
- We keep facts and a link to each original record, never copies of government documents; some tools read the official portals live instead of storing anything.
- Every page and email names its sources and the date of the data.
- People's names are shown only where a tool needs them, never to anonymous visitors, and anyone can ask to be left out.
- Leads point contractors to direct mail, never to automated calls or texts.
