    How it works

    Your portfolio stays on your device. On-chain history and prices route through a privacy proxy — no ledger payload logging.

    ZeroTrack data flow diagram The ZeroTrack app runs locally on your device. Exchange imports happen directly using read-only keys. On-chain history and pricing data is fetched via a server-side proxy with minimum viable logging. Sync uses end-to-end encryption.
