Your addresses stay in this browser. They are saved in this browser's local storage only, never in the page link, and this page has no server, cookies or analytics. To read balances your browser asks 9mm's public data API, the public Switch subgraph, PulseChain and Ethereum RPC nodes (Watergun and Uniswap positions are read straight from Ethereum) and DexScreener (Ethereum prices) directly, so those services see the addresses or tokens being looked up, as they would for any wallet app. LibertySwap's data needs a private key, so those lookups go through a Ching Ching relay on Cloudflare. It saves nothing, but Cloudflare's request logs for it show the address for a limited time.
