-Key features include:
-
-- SimpleFIN bank sync integration (auto-sync, manual "Sync Now", 90-day backfill)
-- Subscription catalog with recommendations from unmatched charges
-- Advisory non-bill filter system (5k+ patterns, auto-matching)
-- Transaction import, matching, and management
-- Snowball and avalanche debt payoff planning
-- Analytics, calendar, summary pages, and printable reports
-- Dark mode and PWA support (offline-ready)

## Security Notes
- Auth is required for user data routes.
- Admin routes require an admin session.
-- User-owned bill, category, payment, import, export, and settings routes derive ownership from the authenticated session.
-- CSRF uses a double-submit cookie pattern. The SPA reads `bt_csrf_token` with `document.cookie` and sends it as `x-csrf-token` on mutating requests.
-- Do not set `CSRF_HTTP_ONLY=true` for this SPA unless token delivery changes.
+- User-owned bill, category, payment, import, export, transaction, and settings routes derive ownership from the authenticated session.
+- CSRF uses a double-submit cookie pattern. The SPA fetches `/api/auth/csrf-token`, stores the token in memory, and sends it as `x-csrf-token` on mutating requests.
+- The CSRF cookie defaults to `HttpOnly`; JavaScript does not need to read it through `document.cookie`.
- Session cookies are HTTP-only and SameSite-protected.
- Password changes rotate the current session and invalidate other sessions.
-- Rate limits protect local login, password changes, imports, exports, admin actions, and OIDC routes.
+- Rate limits protect local login, password changes, imports, exports, admin actions, backup actions, and OIDC routes.
- Security headers include CSP nonces and standard hardening headers.
- Audit logging records security-sensitive events such as login, logout, password changes, role changes, CSRF failures, and migration operations.
-Backups and exports can contain sensitive financial data. The app writes SQLite backup files with restrictive permissions, but backup/export encryption is not implemented. Protect downloaded files and mounted volumes yourself.
