Privacy Policy

Overview

This Privacy Policy explains how Bit2Bus ("we," "our," or "us") handles information in our mobile application and web services. Bit2Bus is committed to protecting your privacy through a privacy-first design approach.

Information We Do NOT Collect

Bit2Bus is designed with zero data collection principles. We explicitly do NOT collect, store, transmit, or have access to:

• Personal Information: No names, email addresses, phone numbers, or personal identifiers

• Location Data: No access to your geographic location or movement patterns
• Network Activity: No monitoring of your internet usage or network connections
• Contacts or Files: No access to your contacts, photos, files, or other device content
• Behavioral Data: No profiling or analysis of your behavior patterns

Local Data Storage

The app stores minimal information locally on your device to provide functionality:

Settings Data (Stored Locally Only)

• Language Preference: Your selected language (English, German, French, Spanish, or Italian)
• Theme Preference: Your selected theme (Light, Dark, or System)

This locally stored data:

• Is not transmitted to any servers or third parties
• Can be completely cleared by uninstalling the app
• Is not accessible to other applications on your device
• Is not synchronized across devices
• Contains no personally identifiable information

App Permissions

Bit2Bus requests minimal permissions and explains each one:

• No Social Media Integration: No data is shared with social media platforms
• No Cloud Services: No data synchronization or cloud storage services
• No Crash Reporting: No automatic crash reporting to external services

Data Security

Since we collect no data about you, there is no risk of:

• Data breaches exposing your personal information
• Unauthorized access to your data
• Data being sold to third parties
• Government surveillance of your app usage
• Identity theft from compromised app data

Bit2Bus does not knowingly collect any information from children under 13 years of age. Since we collect no personal information from any users, children can safely use the app without privacy concerns.
