* fix: gracefully handle invalid family timezone instead of crashing Family#timezone is a free-text IANA zone name with no validation on write. If it becomes stale (e.g. tzdata renames a zone, like the historical Europe/Kiev -> Europe/Kyiv switch) or a migration meant to remap legacy names never ran, Localize#switch_timezone passed the raw string straight to Time.use_zone, which raises ArgumentError for any unrecognized zone. Since switch_timezone runs as an around_action on every request, this crashed the entire app for the affected family, including the login page. Now validates the zone via ActiveSupport::TimeZone[] first and falls back to the app default (logging a DebugLogEntry) instead of raising. The log write is debounced per (family, bad value) via Rails.cache (once per day) so an affected family doesn't write one DebugLogEntry row per page view indefinitely. Fixes #390 Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix: address review feedback on timezone fallback - Make the invalid-timezone debounce lease atomic. Rails.cache.fetch is read-then-write, not atomic, so two concurrent requests could both observe a cache miss and both log before either write landed. Rails.cache.write(unless_exist: true) maps to Redis's atomic SET NX in production, so only one request ever wins the lease. (via CodeRabbit) - Stop using "Europe/Kiev" as the invalid-timezone value in tests. Whether ActiveSupport::TimeZone still resolves that legacy alias depends on the host's installed tzdata version (tzinfo-data is Windows/JRuby-only per Gemfile), so the test's pass/fail behavior wasn't deterministic across machines/CI. Use a deliberately nonexistent name instead. (via Codex) Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix: validate Family#timezone on write to address root cause of #390 The previous commit made the *crash* graceful, but left the actual defect in place: nothing stopped an unrecognized IANA zone name from being written to Family#timezone in the first place (direct DB/API access, an old dump predating a tzdata rename, or a future rename of a currently-valid zone). Add a Family-level validation using the same ActiveSupport::TimeZone[] lookup Localize#resolved_timezone uses at request time, so "valid at save" and "valid when rendering" can't drift apart. Deliberately not `inclusion: { in: ActiveSupport::TimeZone.all.map(&:name) }`, matching the neighboring locale/date_format validations: verified empirically that the settings form submits `tz.tzinfo.identifier` (e.g. "America/New_York"), not `tz.name` (e.g. "Eastern Time (US & Canada)"), and those differ for all 150 zones Rails ships. An inclusion check against `.name` would have rejected every legitimate value the form submits. The validation only runs when timezone is actually being changed (if: :timezone_changed?). A family with a pre-existing bad value (the exact #390 scenario) must still be able to save unrelated changes -- otherwise this would turn a previously-harmless bad value into a blocker for any other settings update or background job touching that family's record.

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.
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.
