Recover my access
Enter the personal recovery code saved on your other device. Your working copy will open in an empty local project or in a new project, without replacing work already stored here. An existing draft synchronization will reconnect; a collaboration recovery key restores the published tree and your participation.
I lost my collaboration key
Request a link using the recovery address you confirmed in My participation. This restores your participation and the published tree, not an unpublished private draft. There is no global account. Solo projects currently use their personal code or an .hgs backup.
Fictional invitee’s view
A story to build together
You’re invited to join a family tree
Together, enrich your family history and share your discoveries.
Your starting point
This is the person from whom you can start enriching the family tree.How would you like to appear?
How does collaboration work?
Build your family history together, respecting everyone’s contributions.
Start with your close family
You can freely add, change or remove information about your starting person and their close relatives: parents, siblings, partners and children. This is your starting area.
Enrich the tree step by step
Add missing people and their family links. Each person you document can become the starting point for new discoveries as your research progresses.
Respect others’ work
Outside your initial area, the participants concerned may be invited to review changes or removals you propose. Discuss them together to keep the shared tree consistent.
Explore freely, contribute where you’re involved
You can explore the whole tree. Branches too far from your contributions remain read-only: contact the people documenting them to enrich those branches.
What happens to my contributions?
A family tree grows through shared work. Your contributions can remain useful even after you leave.
Your contributions are shared
People, links and information you publish are accessible to other participants. They can enrich them or suggest corrections, respecting the collaboration rules.
You can leave at any time
Your participation ends and notifications are disabled. Your contributor identity is anonymized; published genealogical information stays in the shared tree.
Family history is preserved
Leaving does not remove work others have relied on. Anonymization concerns your contributor identity, not the people or genealogical information you documented.
Collaboration relies on trust
Everyone commits to contributing in good faith, sharing reliable information and respecting others’ work.
No account needed.
Welcome! Your tree is ready on this device. You can enable device synchronization later.
