Stonkastic is an email-sign-in app for buying and selling tokenized stocks with USDC on Arc. This page explains what we collect and why.
If you sign in, Privy stores your email and creates embedded wallets for you. We see the email you use, your Arc cash address, and a Solana address for xStocks. Trades, balances, and transfers are on public chains. We do not ask for a password or a seed phrase.
Device storage on this browser keeps your watchlist and local activity so the app can show recent moves. That data stays on the device unless you clear the site.
We do not sell your email. We do not store your private key. Export Key opens a Privy screen so you can copy the key yourself. We cannot read that key.
Sign-in and wallets go through Privy. Quotes and fills go through Relay. Prices and on-chain stats come from Birdeye and public RPCs. Those services see the requests needed to run the trade.
