Privacy Policy

Last updated: April 2026

Memory Trainer ("the App") respects your privacy. This policy describes what data we collect and how we use it.

1. Data We Collect

• Wallet address — your public Solana wallet address, used to identify your account and store game scores.
• Game scores — your best scores and play counts for each mini-game.
• Transaction signatures — on-chain transaction signatures for payment verification and seeker tasks.

2. Data We Do NOT Collect

• Private keys or seed phrases
• Personal identity information (name, email, phone)
• Location data
• Device identifiers or advertising IDs
• Cookies or tracking pixels

3. How We Use Your Data

Your wallet address and scores are stored in our database to display your game progress, achievements, and leaderboard rankings. Transaction signatures are stored to prevent duplicate payment claims.

4. Data Storage

Data is stored in Supabase (PostgreSQL) with row-level security policies ensuring you can only access your own records.

5. Third Parties

We do not sell or share your data with third parties. We use Solana RPC providers (Helius) to interact with the blockchain.

6. Data Deletion

Contact us to request deletion of your game data. Note that on-chain transactions cannot be deleted as they are part of the public blockchain.

7. Changes

We may update this policy. Changes will be posted on this page.
