All AI processing happens on your device, powered by Google AI Edge LiteRT-LM running Qwen 2.5. Your transactions are parsed, stored, and analyzed locally; there are no accounts, no analytics SDKs, and no servers collecting your data. Two things do touch the network, both easy to verify in the source: multi-currency features can fetch exchange rates from open.er-api.com, and the "report a parsing problem" flow opens pennywise.zynth.dev, which immediately parses the pre-filled SMS text and sender ID server-side to generate a preview before you submit anything. Everything else stays on your phone. The entire codebase is open source (AGPL v3) so anyone can check each of these claims.
