Privacy Policy

Overview

SolFloLab is a non-custodial payment link service for Solana. We are committed to protecting your privacy. This policy explains what data we collect and how we use it.

Data We Collect

• Wallet Addresses: Public wallet addresses used to create and receive payments. These are public by nature on the Solana blockchain.
• Payment Link Data: Amount, currency, title, and description you provide when creating payment links.
• Transaction Signatures: On-chain transaction identifiers for completed payments.
• Analytics: Anonymous usage data via Vercel Analytics (page views, no personal data).

Data We Do NOT Collect

• Personal identification information (name, email, phone)
• IP addresses or precise location data
• Private keys or seed phrases (we never have access to these)
• Cookies for tracking purposes

Private Payments

When you enable the Private Payment feature:

• Payments are routed through the Privacy Cash ZK pool
• Neither sender nor receiver wallet addresses are visible on-chain
• We store a placeholder signature instead of the actual transaction
• Privacy Cash's own privacy policy applies to their service

Data Storage

Payment link data is stored in Supabase (PostgreSQL). We retain this data to display your payment history and link status. You can delete your payment links at any time from your dashboard.

Non-Custodial

SolFloLab is fully non-custodial. We never hold, control, or have access to your funds. All payments flow directly from payer to recipient on the Solana blockchain.

Third-Party Services

• Supabase: Database hosting
• Vercel: Website hosting and analytics
• Helius: Solana RPC provider
• Privacy Cash: ZK privacy infrastructure
