# Totals > Totals is a privacy-first personal-finance app for Ethiopia: it reads bank > SMS on-device (CBE, Awash, BOA, Dashen, Telebirr, …) and keeps financial > data on the phone. Its Data Sync feature can push a user's records — > transactions, accounts, budgets — to a server the user controls, as > one-way JSON over HTTPS. ## Docs - [Data Sync backend contract](/sync.md): the complete receiver contract — requests, auth, status codes and retries, payload schemas, delete semantics, and a single-file reference server. - [Privacy policy](/PRIVACY_POLICY.md): what leaves the device and what never does.
