SparrowPrivacy Policy
Sparrow is a read-only portfolio tracker. It never asks for, stores or transmits private keys, seed phrases or exchange credentials, and it cannot move funds.
Data stored on your Mac
- Portfolio names, wallet labels and the public wallet addresses you add, stored in the app's sandbox container.
- Preferences (currency, refresh interval, tax settings), stored in the app's local preferences.
- Optional API keys you enter (Etherscan, CoinGecko Demo), stored in the macOS Keychain.
- Cached market and blockchain responses, stored in the app's cache folder.
The developer operates no servers, collects no analytics and never receives any of this data.
Data sent to third-party services
To show balances and prices, Sparrow sends requests directly from your Mac to:
- CoinGecko: coin identifiers and your display currency. Privacy policy
- Alchemy, Etherscan, Blockscout, Routescan and public RPC nodes: the public EVM addresses you add. Alchemy · Etherscan
- mempool.space and Blockstream: the public Bitcoin addresses you add. mempool.space · Blockstream
These providers may log requests (including your IP address) under their own policies. Public addresses are visible on their blockchains by nature.
