SolanaStake

Privacy Policy

Last updated: 5 May 2026

1. Introduction

This Privacy Policy explains how SolanaStake at solanastake.app ("we", "our", or "the Service") collects, uses, and protects information when you use our web application or mobile app (including the Solana dApp Store version for Seeker devices) to track your Solana staking portfolio.

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, or Seed Vault on Seeker) 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 Mobile Wallet Adapter (Seeker Devices)

When using the Service on Solana Seeker devices or other Mobile Wallet Adapter (MWA) compatible devices:

  • Connection uses the Solana Mobile Wallet Adapter protocol
  • Your wallet address is requested via the Seed Vault or compatible wallet app
  • Authorization is cached locally on your device for convenience
  • You can revoke authorization at any time through your wallet settings

2.4 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.

2.5 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 Liquid Staking Token (LST) balances for Premium users
  • Compute and store mark-to-market LST reward records (when Premium users opt in via the "Include liquid staking rewards" option). These records are derived from public on-chain events and historical exchange rate snapshots, and are keyed to the wallet address you queried so they can be returned to you on subsequent requests without re-computation.
  • Fetch historical SOL/USD price data for tax calculations
  • Generate reports and CSV exports for your records

We also run a periodic background job that (a) snapshots current LST/SOL exchange rates once per UTC day from public market data, and (b) incrementally backfills historical staking rewards for stake accounts that have previously been queried through the Service, so the next time those accounts are loaded the data is already present. This job operates on stake account addresses you have already submitted; it does not discover or sync new wallets on its own.

5. Third-Party Services

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

  • Helius - Solana RPC provider for blockchain data and token balances
  • Dune Analytics - Historical staking rewards data
  • Jupiter - Liquid staking token exchange rates
  • CoinGecko / CryptoCompare - Historical price data

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

6. Data Security & What We Persist

The Service operates without traditional account registration — we do not collect names, email addresses, passwords, or other personally identifying information. The data we do persist is limited to what is needed to deliver Premium features and to avoid re-computing the same on-chain data on every request:

  • Wallet addresses you have queried and any aliases you have set for them
  • Premium subscription status, plan, and renewal/expiry dates linked to your wallet address
  • Payment transaction signatures used to verify subscription purchases
  • Cached on-chain data: stake account histories, native staking rewards, liquid staking token events, and (when Premium users opt in) computed mark-to-market LST reward records
  • Daily LST/SOL exchange rate snapshots (public market data, not user-specific)

All traffic to the Service is encrypted in transit using TLS. Persistent storage uses a managed PostgreSQL instance with encryption at rest. Short-lived caches (Redis, in-process) hold only derivative computation results and expire automatically.

7. Your Rights & Data Deletion

You can stop providing wallet addresses to the Service at any time by disconnecting your wallet and ceasing to enter addresses manually. Disconnecting immediately revokes the Service's ability to read your address from your wallet.

For any wallet address you have used with the Service, you can request deletion of the stored records associated with that address (subscription status, aliases, cached on-chain data, MTM reward records) by opening an issue on our GitHub repository and including a signed message from the wallet to prove ownership. Public on-chain data itself cannot be removed because it lives on the Solana blockchain, but we will purge our local cached copy keyed to your address.

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.
