Scanning receipts is a quick way to log expenses, but sending those images to remote cloud servers exposes highly sensitive information. Invoices contain tax details, specific purchased items, location data, and payment methods. Storing this information in centralized server databases is an unnecessary security risk.
Why Lumi's OCR Keeps Original Photos Safely in Your iOS App Sandbox. Learn how secure, on-device smart receipt scanning makes expense tracking effortless without ever uploading your personal financial data to the cloud.
"Your receipts represent some of your most specific spending logs. Storing them on cloud databases is a trade-off you don't need to make."
