What Biscuit connects to

Biscuit only connects to what it needs, and tells you here exactly what that is. None of these connections carries your seed or your keys.

To	Why	Who sees your IP address
A Monero node	Monero sync and payments	The node, unless it goes through Tor or it’s your own
Electrum servers	Bitcoin and Litecoin	The server, unless you use Tor or your own server
biscuitwallet.com	Prices, currency rates, the Journal, crowdfunding, updates	Our server, which keeps no logs of these. In Tor mode: nobody, through our onion
Rendezvous servers and market makers	Atomic swaps	Them, unless you tick Connect through Tor
Biscuit’s swap service, Trocador, the exchange	Exchange swaps	All three (see the privacy policy)

Opening a link, a block explorer for example, opens your browser; Biscuit asks first when Settings › Display › Warn before opening external link is on.

What Biscuit never does

No accounts, no analytics, no crash reports, no identifier sent with requests.
No remote configuration: what Biscuit does is decided by the version you installed.
It never connects to Feather’s servers. Biscuit is built on Feather, but uses its own.
Your keys and seeds never leave your computer.

Turning connections off

Third-party data can be disabled: no prices, no Journal, no update checks.
Settings › Network › Offline disables every connection, for offline signing.
Your own node and Electrum server replace the public ones.
