* fix(reports): a transfer out is not a sale A negative quantity is all it took to be counted as a sale. So moving an asset to another account you own — a transfer, a sweep, an exchange — was listed among the period's sales, and its cost basis was compared against that day's price to book a gain nobody made. Nothing was sold and nothing was realised. The labels for this already exist and are already trusted elsewhere: Transaction::INTERNAL_MOVEMENT_LABELS keeps the same four out of the income statement, for the same reason. The investment report just never consulted them. Two places learn to ask. Trade#realized_gain_loss returns nil for an internal movement, so no caller can book the gain; and the report's query leaves those trades out, so the movement is no longer counted or listed as a sale it never was.

On cash that means a currency exchange and really is internal. On a security the label covers "currency **or** security exchanges" — the repo's own guide says so — and a security-for-security exchange can dispose of an appreciated asset. So a labelled exchange dropped out of the sales report *and* `realized_gain_loss` returned nil for it. The gain did not move; it stopped existing. The two errors are not symmetrical, which is what decided this. Listing a movement that was not a sale is visible and correctable. Erasing a realized gain is neither — nothing on the page says a figure is missing. So the trade list keeps only the labels that unambiguously preserve ownership, and leaves the ambiguous one where the user can see it. Also from review: the test asked for `period: "last_30_days"`, but the controller reads `period_type`, so the request silently fell back to the current month and the trades dated three days earlier dropped out of range on the 1st to the 3rd. Confirmed with `travel_to Date.new(2026, 9, 2)`: fails on the old parameter, passes on the new one.

Sure: The personal finance app for everyone
Get involved: Discord • Website • Issues
Important
This repository is a community fork of the now-abandoned Maybe Finance project.
Learn more in their final release doc.
Backstory
The Maybe Finance (archived/abandoned repo) team spent most of 2021–2022 building a full-featured personal finance and wealth management app. It even included an “Ask an Advisor” feature that connected users with a real CFP/CFA — all included with your subscription.
The business end of things didn't work out, and so they stopped developing the app in mid-2023.
After spending nearly $1 million on development (employees, contractors, data providers, infra, etc.), the team open-sourced the app. Their goal was to let users self-host it for free — and eventually launch a hosted version for a small fee.
They actually did launch that hosted version … briefly.
That also didn’t work out — at least not as a sustainable B2C business — so now here we are: hosting a community-maintained fork to keep the codebase alive and see where this can go next.
Join us!
Hosting Sure
Sure is a fully working personal finance app that can be self hosted with Docker. Sure can be accessed from a browser, the macOS desktop app, the mobile app, API clients, and LLM agents. See Sure Clients for an overview.

Performance Issues
With data-heavy apps, inevitably, there are performance issues. We've set up a public dashboard showing the problematic requests seen on the demo site, along with the stacktraces to help debug them.
