Common Questions
Can merchants see my receipt data after it's encrypted?
Can merchants see my receipt data after it's encrypted?
Merchants generate receipts but only see what they already know from the transaction. The encrypted version sent to your bank is unreadable without your private key, which only exists on your device.
What if I lose my phone?
What if I lose my phone?
Your private key is stored in hardware security (iOS Secure Enclave, Android KeyStore) that requires biometric or PIN authentication. Key backup and recovery follows the same secure protocols as your banking app access—if you can recover your banking app, you can recover your receipt keys.
Can I export my receipt history for tax purposes?
Can I export my receipt history for tax purposes?
