ReceiptTracker is a personal, single-user tool. It reads photos of the owner's own purchase receipts, stores the extracted details (merchant, date, totals, category) in a private ledger, and answers questions about the owner's past purchases.
It connects to the owner's own Google Drive to read a receipts inbox folder and to keep its own files (archived receipt images, a ledger database and a summary spreadsheet). It is not offered to the public and has no other users.
