ContactFlow Privacy Policy

1. Introduction

ContactFlow ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our mobile application ContactFlow (the "App").

By using our App, you agree to the collection and use of information in accordance with this policy. If you do not agree with the terms of this Privacy Policy, please do not access the App.

2. Information We Collect

2.1 Personal Information

ContactFlow is designed to work with your existing device data and does not collect personal information from external sources. We access the following data that you already have on your device:

• Contact Information: Names, phone numbers, email addresses, and addresses from your device's contact list
• Call Logs: Call history including phone numbers, call duration, timestamps, and call types (incoming, outgoing, missed)
• Calendar Events: Event titles, descriptions, dates, times, locations, and attendees from your device's calendar
• SMS/MMS Messages: Message content, timestamps, and phone numbers for conversation grouping
• Location Data: Your current location (only when you use location-based features like travel time calculations)

3. How We Use Your Information

We use the information we collect to:

• Provide and maintain the App's core functionality
• Group SMS messages into conversation threads for better organization
• Calculate travel times between locations when you request this feature
• Create calendar events based on your communication history
• Display your recent contacts and activities in a unified interface

4. Data Storage and Security

4.1 Local Storage

All your data is stored exclusively on your device using SQLite database. We do not transmit any personal information to external servers whatsoever. The App includes:

• Local caching of contact information for improved performance
• Local storage of call logs and SMS data for conversation grouping
• Local calendar event caching for faster access
• Intelligent memory management with automatic cleanup of old cached data

4.2 Data Security

We implement appropriate security measures to protect your information:

• All data is stored locally on your device using secure database practices
• We use Android's built-in security features and permission system
• Data is automatically cleaned up to prevent excessive storage usage
• No personal data is ever transmitted to external servers - all data remains private and local on your device
• The only external communications are native app calls to your device's built-in applications (contacts, calendar, phone), which you explicitly initiate

5. Permissions We Request

ContactFlow requests the following permissions to provide its functionality:

5.1 Essential Permissions

• READ_CONTACTS: To access your contact list for displaying contact information
• READ_CALENDAR: To read your calendar events for the agenda view
• WRITE_CALENDAR: To create calendar events when you log interactions
• READ_CALL_LOG: To access your call history for the recent contacts view

5.2 Optional Permissions

• READ_SMS / SEND_SMS: To group SMS messages into conversations and send SMS with travel time estimates
• ACCESS_FINE_LOCATION / ACCESS_COARSE_LOCATION: To calculate travel times and provide location-based features
• READ_PHONE_STATE: To access phone state information for call logging

Note: You can deny optional permissions and still use most of the App's features. Essential permissions are required for core functionality.

6. Data Sharing and Disclosure

ContactFlow does not transmit, sell, trade, or otherwise transfer any personal information to external servers or third parties. All your data remains on your device.

The only way your information may leave your device is through native app calls that you explicitly initiate:

• Native App Integration: When you explicitly choose to share information through native app calls (e.g., opening a contact in your device's contact app, making a call through your device's phone app, or creating a calendar event in your device's calendar app). These actions are handled by your device's native applications, not by ContactFlow servers.

No personal data is ever transmitted to external servers. We do not use analytics services or crash reporting services that would access your personal information.

7. Third-Party Services

ContactFlow integrates with the following third-party services:

• Google Maps: For displaying maps and calculating travel times (when location permission is granted)
• Device Calendar Apps: For reading and creating calendar events
• Device Contact Apps: For accessing and managing contact information
• Device Phone Apps: For making calls and accessing call logs

These integrations use your device's native apps and do not transmit data to external servers.

8. Data Retention

We retain your information as follows:

• Contact Data: Cached for up to 24 hours for performance optimization
• Call Logs: Cached for up to 8 hours for recent activity display
• SMS Data: Cached for up to 8 hours for conversation grouping
• Calendar Events: Cached for up to 15 minutes for agenda display
• Location Data: Not stored permanently; used only for immediate calculations

All cached data is automatically cleaned up to prevent excessive storage usage.

9. Your Rights and Choices

You have the following rights regarding your information:

• Access: You can view all data the App has access to through your device's settings
• Control: You can revoke permissions at any time through your device's app settings
• Delete: You can uninstall the App to remove all locally stored data
• Opt-out: You can disable location services or other features that require permissions

10. Children's Privacy

ContactFlow is not intended for use by children under 13 years of age. We do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe your child has provided us with personal information, please contact us.

11. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy in the App and updating the "Last Updated" date. You are advised to review this Privacy Policy periodically for any changes.
