What this gives you
When this is on, contacts saved in PixWork are written out to the phone’s own contact book.
Useful for seeing a caller’s name on an incoming call, or picking someone quickly from a messaging app like WhatsApp. Scan a card once and that person stops being an unknown number.
Only contacts that have a phone number are written out. A contact with no number is skipped.
One way, from PixWork to the phone
This is a one-way write-out from PixWork into the phone’s contact book. Edits or additions made in the phone’s own contacts app do not come back into PixWork.
The setting is labelled "Automatic sync to the OS contact book" in the app, but it behaves as described above — a write-out only, not a two-way sync.
A failed write-out does not undo the save on the device. By design, a failure here does not stop or roll back the save inside the app.
How Android and iOS differ
Where the contact lands depends on the platform.
| Platform | Where it is written | State |
|---|---|---|
| Android | Creates a dedicated PixWork account and writes only underneath it | Published |
| iOS | Adds the contact to a "PixWork" contact group | The App Store build is not published and on-device verification is not complete |
The iOS implementation saves into the device’s default contact container and then adds the entry to a PixWork group. Being in a group is not the same as being stored apart from what was already there. iOS has not been confirmed to give the same separation as the dedicated account on Android.
What happens on deletion
Deleting a contact inside the app also removes it from the OS contact book, if it had been written out there and a phone number is stored.
Setting a row’s Status to "Deleted" in the sheet marks that contact deleted inside the app, so it drops out of the list. It does not remove it from the phone’s address book.
Setting Deleted in the sheet does not clear the contact from everyone’s phone address book — that is a common misreading and does not match the implementation.
