Public wallet data and storage
Sirius.fi reads your public wallet address, positions and on-chain transaction history. It does not request private keys or seed phrases and has no application user database. Your address passes through the server RPC proxy to Helius when data is requested. Public share links expose position data and may link to the current owner on Solscan. Shared-position results and public prices are cached on the server.
Your browser stores wallet preferences, wallet-specific history caches, and price and token-registry caches in localStorage. Wallet-specific history caches stay in your browser while the same wallet is connected, and are cleared when you switch to another wallet or disconnect. Closing the tab does not clear them. You can clear site data in your browser settings.
Hosting and analytics
The site uses Vercel hosting and Vercel Web Analytics for page views. Before sending an analytics event the app removes every query parameter except the short marketing labels utm_source, utm_medium, utm_campaign, utm_term and utm_content, drops the URL fragment, and redacts position and wallet addresses in the path. Hosting and service providers may process IP addresses, request URLs and other request metadata under their own policies; the application cannot promise that those providers never log a wallet address or public position URL.
External services
Data requests use Helius/Solana RPC, Raydium, Jupiter and CoinGecko. Token logos can load directly from third-party hosts and expose your IP address to those hosts. WalletConnect/Reown and the chosen wallet provider process connection requests under their own policies. Raydium and Solscan links open external sites.
The application does not intentionally log wallet addresses, private keys or API keys. It keeps temporary process-local request counters for abuse prevention. Provider retention periods and wallet-provider behavior are outside this codebase and should be checked in their policies.
An optional tip becomes a public Solana blockchain transaction if you approve it. Blockchain records cannot be removed by Sirius.fi.
