OneSpend is an offline-first personal finance manager. (i) Sync is opt-in: the app never connects to a hardcoded server - the user picks the backend URL in Ajustes -> Conexiones (the bundled default is the author's public server, only used if the user enables sync, and overridable in-app without a rebuild). (ii) UI is wrapped for es + en; the language selector is in the side menu. **Default servers** — the build ships with these defaults, which you can override in `Settings → Connections` after install: * Sync server: `https://onespend-back.dowar.xyz` * SSO server: `https://auth.dowar.xyz/api` (login panel: `https://auth-panel.dowar.xyz`) The author maintains these as a public service for anyone who does not want to self-host. To use a self-hosted sync server and/or SSO, change the URLs in the Connections screen (no rebuild needed). The SSO source is public at `https://gitlab.com/dowardev/sso`.
