What it does
Select a person and add a partner, child, sibling or parents. GenoCanvas draws the new people and lines and keeps each generation on its own row. You can also draw any line by hand.
- Couples: married, engaged, living together, separated, divorced, widowed, or a casual relationship, with dates.
- Children: biological, adopted and foster, and fraternal or identical twins.
- Relationships between people: close, distant, cut-off, conflict, abuse, neglect and others, with a direction where it matters.
- Markers for health or other characteristics that you name and colour yourself, household outlines, ages and years, and a key that lists only what you used.
- Mouse, touch or keyboard, with undo and redo, on a laptop, tablet or phone.
Where your work goes
Nowhere. Here is why that is true, and how to check it yourself.
| Network | Once the page has loaded, its security policy forbids every network request. Switch off your Wi-Fi and carry on drawing, or watch the Network tab in your browser’s developer tools while you work: it stays empty. |
|---|---|
| Accounts | The app has none. |
| Tracking | No analytics, no cookies, and no code from anyone else: the app is one file we wrote. |
| Storage | In your browser if autosave is on (you can turn it off on a shared computer), and in files you save. Both stay on your device. |
| What it does not cover | GenoCanvas does not encrypt your files, and it cannot protect an unlocked or shared computer. Keep drawings where you keep your other client records, and use initials in the free version. Browsers can clear saved data, so save a file as your backup. |
