How it works

INPUT

Family data entered, invited or imported (GEDCOM 7.0, desktop helper for Google Takeout, OneDrive, Dropbox)

CODE

People and relationships stored as nodes and edges in Neo4j

CODE

Privacy guard and central policy guard on every read and write

HUMAN

Families and society reviewers verify records and approve archive items

CODE

Files encrypted at rest; tamper-evident audit log

AI boundary

Where AI is used

In the build: AI-assisted development across web, mobile and desktop, directed and reviewed by a human lead
Considered, not shipped: duplicate-person suggestions — human merges, never auto-merge

Where AI is excluded

No generated ancestors or inferred relationships presented as fact
Tree structure from explicit input, GEDCOM import and review
Access from identity (Nordic eID), role and policy, not AI judgments

Guardrails

Organisation-scoped queries and a central policy guard on every society read and write
Multi-axis privacy guard in front of all family-graph reads
AES-256-GCM at rest, separate personal and society vault keys
Tamper-evident audit log retained for seven years
GDPR Article 15 data export built in

Notes

Role: founder. Product strategy, IP and trademark strategy (FI/EU/US/Middle East), grant funding and go-to-market. Hands-on technical lead, directing AI-assisted development across web, mobile and desktop.

The data model is graph-native, with one shared platform for personal and society use. Every society read and write goes through organisation-scoped queries and a central policy guard, so access depends on identity, role and policy rather than hardcoded rules.

Privacy is GDPR by design: files encrypted at rest with AES-256-GCM and separate keys for personal and society vaults, a multi-axis privacy guard in front of all family-graph reads, a tamper-evident audit log kept for seven years, and built-in GDPR Article 15 data export.

In genealogy, a confident wrong answer is worse than no answer. The product invests in evidence and review instead of generated relationships.
