Records are saved on the device first
A contact you have checked, corrected, and saved is stored on the device first. Card images are stored on the device too.
Everything beyond that is optional. Syncing to Google Sheets and writing out to the phone’s contact book can each be turned on independently. Scanning and saving work with neither of them on.
On-device data is lost if the app is uninstalled.
Card images and AI analysis
When a card is read by AI, the card image is sent through PixWork’s proxy to an external AI service. That external service performs the reading and the result comes back to your device.
QR scanning does not use this path. It runs entirely on the device, so neither an image nor the contents of the code leaves it.
See the Privacy Policy for the details, including how data is handled by the external AI service.
Google Sheets is not a backup feature
With the Google Sheets connection on, synced contacts are also stored in the sheet. That is not a complete backup feature.
- Card images are not stored — only text data reaches the sheet
- Only the synced columns are covered — see "Google Sheets column layout" for the list
- In the current implementation, only contacts updated within the last 90 days are in scope — anything older is not sent to the sheet
There is no guarantee that all local data can be fully recovered after a device change. Picking the same sheet again pulls the rows that are in the sheet into the app, but only those. Images, fields outside the synced columns, and contacts last updated outside the 90-day window of the current implementation do not come back.
What deletion actually removes
Deleting a contact inside the app removes the on-device record. If it had been written out to the OS contact book, it is removed from there too, provided 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.
