+ Privacy Policy
+
+
Last updated: September 9, 2026
+
+
+ Osias is a browser extension that helps you notice and interrupt loss-driven trading by watching your
+ connected wallet’s on-chain activity. This policy explains what data the extension and its backend
+ collect, why, and how it’s handled.
+
+
+
What we collect
+
+ Wallet address. Collected when you connect your Phantom
+ wallet — used as your account identifier and to subscribe to your wallet’s on-chain activity.
+
+
+ Authentication data. To verify you control the wallet, you
+ sign a one-time nonce message; we store the resulting session token. Your private key and seed phrase
+ never leave your wallet and are never accessible to us.
+
+
+ On-chain trading activity. While you’re actively
+ connected (extension open, on a supported trading site), our backend subscribes to your wallet’s
+ transaction activity via a Solana RPC provider (Helius) to calculate realized profit/loss. This is
+ public blockchain data, no different from what anyone could see on a block explorer.
+
+
+ Settings. Your configured lock thresholds and cooldown
+ period, stored so they persist across sessions.
+
+
+
What we don’t collect
+
+ - Private keys or seed phrases
+ - Browsing history or page content on any site
+ - Any data from sites other than the specific trading sites Osias supports
+
+
+
Why we collect it
+
+ Solely to run the core feature — detecting loss-driven trading against your configured thresholds and
+ applying/lifting the buy-lock. We do not use this data for advertising and we do not sell it.
+
+
+
Who we share it with
+
+ Helius (our Solana RPC infrastructure provider) receives
+ your wallet address to stream transaction data to our backend, governed by their own privacy policy. We
+ do not otherwise share, sell, or disclose your wallet address, trading activity, or account data to any
+ third party.
+
+
+
Data retention
+
+ Your wallet address, session data, and settings are retained for as long as your account exists.
+ On-chain subscriptions are only active while you have a live connection — we don’t monitor while
+ you’re offline. There’s no self-serve account deletion yet — to request deletion, open an
+ issue at{" "}
+
+ github.com/osias-trade/copilot/issues
+ {" "}
+ and we’ll process it manually.
+
+
+
Your controls
+
+ You can disconnect your wallet and sign out at any time from the extension popup, which revokes access
+ and ends your session.
+
+
+
Open source
+
+ The extension’s frontend is open source (Apache License 2.0):{" "}
+
+ github.com/osias-trade/copilot
+ {" "}
+ — you can review exactly what it collects and transmits.
