Cold Storage Tracker

Cold Storage Tracker is a privacy-first Bitcoin portfolio tracker for manual records and read-only public blockchain data. Record BTC buys, organize them by portfolio group, view cost basis and performance, monitor public addresses or extended public keys, and export JSON backups. No exchange login or app account is required. The app is non-custodial: it does not create, import, store, or use private keys, seed phrases, or signing credentials. It cannot send, receive, exchange, transfer, or custody Bitcoin or any virtual currency. Market and blockchain data come from third-party providers and may be delayed or unavailable. Cold Storage Tracker does not provide investment, tax, or legal advice.
