* fix(security): sanitize exception messages in API responses (FIX-11)
Replace raw e.message/error.message interpolations in response bodies
with generic error strings, and log class+message server-side. Prevents
leaking internal exception details (stack traces, SQL fragments, record
data) to API clients.
Covers:
- API v1 accounts, categories (index/show), holdings, sync, trades,
transactions (index/show/create/update/destroy), valuations
(show/create/update): replace "Error: #{e.message}" with
"An unexpected error occurred".
- API v1 auth: device-registration rescue paths now log
"[Auth] Device registration failed: ..." and respond with
"Failed to register device".
- WebhooksController#plaid and #plaid_eu: log full error and respond
with "Invalid webhook".
- Settings::ProvidersController: generic user-facing flash alert,
detailed log line with error class + message.
Updates providers_controller_test assertion to match sanitized flash.
* fix(security): address CodeRabbit review
Major — partial-commit on device registration failure:
- Strengthened valid_device_info? to also run MobileDevice's model
validations up-front (device_type inclusion, attribute presence), not
just a flat "are the keys present?" check. A client that sends a bad
device_type ("windows", etc.) is now rejected at the API boundary
BEFORE signup commits any user/family/invite state.
- Wrapped the signup path (user.save + InviteCode.claim + MobileDevice
upsert + token issuance) in ActiveRecord::Base.transaction. A
post-save RecordInvalid from device registration (e.g., racing
uniqueness on device_id) now rolls back the user/invite/family so
clients don't see a partial-account state.
- Rescue branch logs the exception class + message ("#{e.class} - #{e.message}")
for better postmortem debugging, matching the providers controller
pattern.
Nit:
- Tightened providers_controller_test log expectation regex to assert on
both the exception class name AND the message ("StandardError - Database
error"), so a regression that drops either still fails the test.
Tests:
- New: "should reject signup with invalid device_type before committing
any state" — POST /api/v1/auth/signup with device_type="windows"
returns 400 AND asserts no User, MobileDevice, or Doorkeeper::AccessToken
row was created.
Note on SSO path (sso_exchange → issue_mobile_tokens, lines 173/225): the
device_info in those flows comes from Rails.cache (populated by an earlier
request that already passed valid_device_info?), so the pre-validation
covers it indirectly. Wrapping the full SSO account creation (user +
invitation + OidcIdentity + issue_mobile_tokens) in one transaction would
be a meaningful architectural cleanup but is out of scope for this
error-hygiene PR — filed it as a mental note for a follow-up.

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 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.
Forking and Attribution
This repo is a community fork of the archived Maybe Finance repo. You’re free to fork it under the AGPLv3 license — but we’d love it if you stuck around and contributed here instead.

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.
