Your data and uninstalling
The app keeps only what it needs to take payments through your Billplz account: your encrypted keys, your collection ID, and for each payment attempt the Billplz bill it made. Bank and card details are entered only on Billplz' own pages and never reach the app. The privacy policy lists everything.
Disconnecting
Settings › Disconnect stops checkout offering Billplz in every market. Bills already paid are not affected. You can connect again at any time.
Uninstalling
Uninstalling removes the app's access to your store at once, and checkout stops offering Billplz. 48 hours later the app erases your keys 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 Billplz account and in your orders in Tringify.
