The reason expense tracking dies for most people isn't laziness — it's data entry. Typing in a month of transactions is miserable, so you stop. The fix is to start from the statement you already have: export it from your bank and let the tool do the categorising.
That's how the import here works — drop in your statement and it reads the transactions and sorts them, with no bank login required (you're uploading a file, not handing over credentials). It's the difference between "I'll do it later" and having your month mapped in a couple of minutes. Just try it with a recent statement and see.
