Your data and uninstalling
The app keeps only what it needs to take payments and refunds through your N-Genius outlet: your encrypted API key and outlet details, and for each payment attempt and refund the N-Genius references needed to check and refund it. Card details are entered only on N-Genius' own payment page and never reach the app. The privacy policy lists everything.
Disconnecting
Settings › Disconnect stops checkout offering N-Genius in every market. Payments already made keep refunding through the outlet that took them. You can connect again at any time.
Uninstalling
Uninstalling removes the app's access to your store at once, and checkout stops offering N-Genius. 48 hours later the app erases your API key and everything else it keeps for your store. If you install it again within those 48 hours, nothing is deleted.
Your payment records stay in your N-Genius portal and in your orders in Tringify.
