Privacy

Sleeve is a product of Carta Bianca Technology. This page explains how we handle the data involved in using Sleeve. A full privacy policy will follow as we approach public launch; the notes below cover the parts that matter most today.

Card recognition

When you scan a card, the photo is processed by automated recognition services — which may include trusted third-party processors — solely to identify the card. These images are used only to return a match. They are not used to identify you, are not used to train recognition models, and are not retained after the scan completes.
