How do I keep my receipts?
The short answer
Attach a photo when you log an expense: under Receipt (optional), tap Attach receipt photo. It’s stored with the expense, and you can download every original in one file.
To get them all, open your Account page (Settings, then your name at the top) and tap Download my records. The file has your records and the original receipts.
Deleting an expense deletes its receipt too.
