Privacy Policy

Last Updated: January 31, 2026

Satu Wallet ("we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains how we handle information when you use our mobile application.

1. Information We Collect

Information stored locally on your device:

• Wallet addresses and public keys
• Transaction history
• App preferences and settings
• Custom tokens you add

Information we may collect:

• Device tokens for push notifications (optional)
• Wallet addresses for transaction monitoring (optional)
• Basic analytics data to improve the app

2. Understanding Wallet Addresses & Derivation Paths

What is a Wallet Address?

A wallet address is a unique identifier (like an account number) that allows you to receive cryptocurrency. Each blockchain network has its own address format:

What is a Derivation Path?

A derivation path is a formula used to generate multiple wallet addresses from a single seed phrase. This follows the BIP-44 standard, allowing your 12 or 24-word seed phrase to create addresses for different cryptocurrencies.

What is a Seed Phrase?

A seed phrase (also called recovery phrase or mnemonic) is a series of 12 or 24 words that serves as the master key to your wallet. From this single phrase, all your wallet addresses across different blockchains are generated.

Public Key vs Private Key

• Public Key: Can be shared freely. Used to generate your wallet address and verify signatures.
• Private Key: Must be kept secret. Used to sign transactions and prove ownership of funds.

3. How We Use Information

We use the collected information to:

• Send push notifications about incoming transactions
• Display your portfolio and transaction history
• Provide cryptocurrency price information
• Enable swap and exchange features
• Improve our services and user experience

4. Third-Party Services

Our app integrates with the following third-party services:

• CoinGecko - For cryptocurrency price data
• Moralis - For blockchain data and transaction monitoring
• LetsExchange - For cryptocurrency swap services
• Firebase - For push notification delivery

Each of these services has their own privacy policies that govern their use of data.

5. Data Security

We implement industry-standard security measures:

• Private keys are encrypted and stored only on your device using expo-secure-store
• We use secure HTTPS connections for all network communications
• We never transmit your private keys or seed phrases
• Optional PIN protection for additional security
• Sensitive data is stored using platform-specific secure storage (iOS Keychain / Android Keystore)

6. Your Rights

You have the right to:

• Delete your data by uninstalling the app
• Opt-out of push notifications
• Export your wallet using your seed phrase
• View your seed phrase within the app (requires PIN if enabled)

7. Data Retention

Local data remains on your device until you uninstall the app. Server-side data (such as push notification tokens) is retained only as long as necessary to provide our services.
