SOL Stake

Privacy Policy

Last updated: January 2025

1. Introduction

This Privacy Policy explains how the Solana Staking Tax Calculator ("we", "our", or "the Service") collects, uses, and protects information when you use our web application to calculate staking rewards for tax purposes.

2. Information We Collect

2.1 Wallet Addresses

When you use the Service, you provide Solana wallet addresses to calculate staking rewards. These addresses are public blockchain data and are used solely to fetch your staking reward information from the Solana blockchain.

2.2 Wallet Connection

You may optionally connect your Solana wallet (e.g., Phantom, Solflare, Coinbase Wallet, Ledger) to the Service. When you connect your wallet:

  • We receive only your public wallet address
  • We use this to verify your identity for Premium subscriptions
  • We store your wallet address and subscription status in our database
  • We record payment transaction signatures for subscription verification
  • For lifetime Premium members, we store that status permanently

2.3 Caching

To improve performance, we may temporarily cache blockchain and price data using Redis or in-memory caching. This cached data does not contain personal information and is automatically cleared after a short period.

2.4 Data We Do NOT Collect

  • We do not collect personal identification information (name, email, etc.)
  • We do not have access to your private keys
  • We cannot access or move your funds
  • We do not use cookies for tracking purposes
  • We do not share your data with third parties for marketing

3. Non-Custodial Service

Important: We Never Have Access to Your Funds

The Service is completely non-custodial. This means:

  • Your private keys never leave your wallet application
  • We can only view your public address and request you to sign transactions
  • Any payment transaction requires your explicit approval in your wallet
  • All your SOL, tokens, and staked assets remain 100% under your control
  • Disconnecting your wallet immediately revokes our ability to see your address

4. How We Use Information

The wallet addresses you provide are used exclusively to:

  • Query the Solana blockchain for staking reward transactions
  • Fetch historical SOL/USD price data for tax calculations
  • Generate reports and CSV exports for your records

5. Third-Party Services

We use the following third-party services to provide our functionality:

  • Helius - Solana RPC provider for blockchain data
  • Dune Analytics - Historical staking rewards data
  • CoinGecko / CryptoCompare - Historical price data

These services may have their own privacy policies. We recommend reviewing their policies for more information.

6. Data Security

All data processing occurs in real-time during your session. We do not persist any user data on our servers. Your wallet addresses and calculated results exist only in your browser session and are not transmitted to us for storage.

7. Your Rights

Since we do not store personal data, there is no data to access, modify, or delete. Each session is independent, and no information persists after you close your browser.

8. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be reflected on this page with an updated revision date.
