SparkSat Privacy Policy

Last updated: June 24, 2025

Introduction

SparkSat is a cryptocurrency wallet browser extension designed for the Spark protocol. We are committed to protecting your privacy and ensuring the security of your digital assets. This privacy policy explains how we handle your information.

Data Collection

SparkSat does NOT collect, store, or transmit any personal user data. Our extension operates entirely locally on your device. We do not:

• Collect personal information such as names, email addresses, or phone numbers
• Track your browsing activity or website visits
• Store transaction data on external servers
• Share any information with third parties
• Use analytics or tracking services

Local Data Storage

SparkSat stores the following data locally on your device using Chrome's storage API:

• Encrypted wallet private keys and seed phrases
• Wallet configuration and settings
• Transaction history and cache data
• User preferences and interface settings

All sensitive data is encrypted using industry-standard encryption algorithms before being stored locally. This data never leaves your device.

Blockchain Interactions

When you perform transactions, SparkSat interacts directly with blockchain networks. These interactions are:

• Broadcast directly to the blockchain network
• Publicly recorded on the blockchain (as is standard for all blockchain transactions)
• Not routed through our servers

Third-Party Services

SparkSat may connect to:

• Blockchain RPC nodes for network connectivity
• Decentralized applications (DApps) that you explicitly choose to interact with

These connections are made directly by your browser and are not mediated by our servers.

Data Security

We implement several security measures:

• All private keys and sensitive data are encrypted before local storage
• No user data is transmitted to external servers
• The extension operates with minimal required permissions
• Regular security audits of our codebase

Children's Privacy

SparkSat is not intended for use by children under 18 years of age. We do not knowingly collect personal information from children.

Changes to This Policy

We may update this privacy policy from time to time. Any changes will be posted on this page with an updated revision date.

Open Source

SparkSat is committed to transparency. Our code is open source and can be audited by the community to verify our privacy practices.
