Features
Everything a spending tracker needs. Nothing it does not.
A Tauri desktop app with a SQLite database on your disk. The only outbound traffic is optional: exchange rates, store pictures when you ask for them, and your own relay once a phone is paired.
Automatic duplicate detection
Overlapping exports never double-count, identical same-day purchases are kept, and a review page handles look-alikes.
Categorisation rules
Ordered rules by substring or regex, applied on import and re-runnable. Manual choices are never overwritten.
Spending dashboards
Spending, income or net over any range, grouped by month, quarter or year. Click through to categories and months.
Multi-currency display
Cached ECB reference rates convert amounts for display. Stored amounts never change.
Stores and items
Link a transaction to a store and list the items bought. Items belong to shared item categories.
Receipts, read offline
Items are found from a photo, screenshot or PDF with built-in text recognition. Nothing is uploaded.
Backups and watched folder
Back up the whole database to one file and restore it later. CSVs dropped in a folder are imported automatically.
Phone relay
Snap a receipt. Your desktop picks it up.
The photo is encrypted on the phone to a key only your desktop holds. The relay server only ever holds scrambled files, until your desktop collects and deletes them. The desktop checks when it starts and then every 5 minutes.
How to pair
Three steps, about a minute.
-
1
Press "Pair phone"
In the FinnyBuddy desktop app, press the Pair phone button. A QR code appears. Codes last 10 minutes.
-
2
Scan it with your phone
Open the camera and scan the QR code. The link carries your desktop's public key, so the server cannot swap in its own.
-
3
Confirm, then send receipts
Name the phone and confirm. After that, take a photo or choose files, and they travel encrypted. Up to 3 phones per desktop.
Already paired? Open the phone app.
Privacy and threat model
What this relay can and cannot see.
The relay sees
- How big each upload is, and when it arrived
- Your IP address when a phone or desktop connects
- That a desktop and up to three phones are paired
The relay cannot see
- The receipt itself: photos and PDFs are encrypted on the phone
- Any bank data: the desktop app never sends it
- The key: only your desktop holds it
An honest limit. The phone app is a web page served by this server. A compromised server could in theory serve a modified page that reads a receipt before it is encrypted. The desktop only ever talks to the one relay address set in its settings, so you can point it at a relay you run yourself.
