Account information

When you create an account, we collect your email address, a hashed version of your password, and optionally your Solana wallet address. We never store your password in plain text.

Payment information

We accept cryptocurrency payments (SOL and USDC) via on-chain deposits. We record transaction signatures, deposit amounts, and your assigned deposit address. We do not collect or store credit card information.

Usage data

We log API request counts (daily aggregates) to enforce plan limits and display usage dashboards. We do not log the content of your gRPC streams or the specific transactions you filter.
