Nexum DNA Tracker

Tracking since Apr 28, 2026.

Changelog

• Jun 5, 2026
  description

  Keep your DNA research organized directly in the match lists — no switching tabs, no separate spreadsheets.
  
  When you manage DNA kits for multiple family members on the same site, the same cousin can appear in every list. Nexum DNA Tracker makes sure your notes and status follow the match person, not the kit — so you only have to figure out who someone is once.
  
  New in v1.0: 23andMe and syncronization between sites
  Nexum now also supports 23andMe.
  By manually connecting people it is now possible so have notes and statuses synced between sites too.
  
  New in v0.4: Match Tool
  Version 0.4 adds a dedicated Match Tool where you can work with all saved matches in one combined view. Search by name, note, Y-DNA, or mtDNA, filter by status and site, and open an expanded detail row to review notes, status, and DNA data per test person.
  
  A widget on every match card
  A small, unobtrusive widget appears on each match, letting you write free-form notes about the connection and mark the match as Started, Solved, or Irrelevant. A colour-coded indicator on the card shows the status at a glance — without affecting the page layout.
  
  Notes shared between kits
  Notes and status are tied to the match person within each site. If the same cousin shows up in three different kits' lists, your note appears in all three automatically. By connecting matches manually you can also sync info between sites.
  
  Works on four sites
  • MyHeritage — match list, individual match page, and shared matches
  • FamilyTreeDNA — Family Finder match list
  • Ancestry — DNA match list, individual match page, and shared matches
  • 23andMe— DNA match list, individual match page, and shared matches
  
  Your data stays with you
  Everything is stored locally in your browser. Nothing is sent to any server. Export all your data as a JSON file at any time and import it on another computer.
  
  Languages
  The widget adapts to the language of the page automatically, or you can override the language manually from the toolbar icon — English, Swedish, German, and Dutch are supported.
