Zero telemetry. All tax computation runs locally — no network calls. Your SSN, income, deductions, and every other piece of tax data lives on your device. We designed it that way from day one. An optional local AI assistant is on the roadmap for the 2026 tax-year filing season (Jan 2027) — strictly opt-in, runs on 127.0.0.1, never enabled by default.
