Principals, staff and the people around them
Keep the household, the advisers, the entities and the documents in one place, without handing the whole picture to a cloud vendor.
ONS Data Terminal holds the people, organisations, holdings, matters and documents behind private and professional work. The relationships, the evidence and the history stay on hardware you control.

Contact, identity, background, legal, financial and digital sections on one record, with documents and change history attached.
Most tools hold the task. This one holds the record. On your hardware.
Contact, identity, background, legal, medical where relevant, financials, digital presence and the relationships that connect the person to everything else.
Participants, documents, chronology, drafts, notes, tasks, expenses and a full change history. Neither is a folder with attachments.
Assets, holdings and insurance policies held against the profile or organisation that owns them, with values converted into one base currency.
Expand from any entity to its immediate neighbours, then one more level, with link types and filters. Nothing is inferred by a model.
Ports, vessels, buildings, aircraft, positions and policies all sit against the same profile or organisation, with one base currency and the documents that support them.




The browser talks to the ONS server on your network. The server writes to PostgreSQL and a file directory you choose. There is no hosted copy, no external query path and no model in the middle.
Users sign in to the server from the browser. Roles decide what they can see and change.
A release binary serves the interface and API from the same origin, bound to loopback, LAN or a private address.
The record lives in a PostgreSQL volume. Uploaded documents stay in a local directory you nominate.
The same register serves a private office, a family office, a professional team or an investigation. The record model stays the same.
Keep the household, the advisers, the entities and the documents in one place, without handing the whole picture to a cloud vendor.
Map ownership across entities and jurisdictions, track positions and insurance, and keep the supporting documents attached to the record.
Participants, chronology, drafts, tasks and expenses stay with the matter. The file still makes sense after the team changes.
Enter the links yourself, expand the graph two levels at a time, and keep the source and the date beside every fact.
