Frequently Asked Questions About Data Privacy

Does ContactVault upload my contacts to a server?

No, absolutely not. ContactVault does not upload, transmit, or send your contacts to any server. All contact data is read and processed exclusively on your device. We have no servers, no cloud infrastructure, and no backend systems that receive your contact data.

Does ContactVault store my contacts on a server?

No, absolutely not. ContactVault does not store your contacts on any external server. Backup files are saved locally in your device's app sandbox. We have no server-side storage of any kind. Your contacts remain on your device at all times unless you explicitly choose to share backup files through iOS system sharing.

1. Introduction

ContactVault ("we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains our data handling practices when you use our iOS application.

Our Core Privacy Principle: Your contacts are your private data. We designed ContactVault from the ground up to process everything locally on your device, ensuring your data never leaves your control.

2. Information We Collect

ContactVault is designed with privacy as a fundamental principle. Here's what we do and don't collect:

What We DO NOT Collect:

• Contact Data: We never transmit your contacts to any external server. All contact processing happens locally on your device.
• Usage Analytics: We do not collect any analytics, tracking data, or usage statistics.
• Personal Information: We do not require accounts, logins, or any personal information to use the app.
• Location Data: We do not collect or use your location.
• Advertising Identifiers: We do not use IDFA or any advertising identifiers.

What We Access Locally:

• Contact Information: Accessed locally on your device solely for creating backups. This data never leaves your device.
• Backup Files: Stored locally in your device's file system. You have full control over these files.

3. How We Use Your Information

Your contact information is used exclusively for:

• Creating backup files in your chosen format (VCF or CSV)
• Encrypting backups when you enable this feature
• Restoring contacts from backup files
• Displaying backup history within the app

Important: All processing occurs locally on your device. We never transmit your data to external servers or third parties.

4. Data Storage and Security

Local Storage

All backup files are stored locally on your device in the app's sandbox. These files remain under your control and can be:

• Shared via iOS sharing mechanisms (AirDrop, Messages, Mail, etc.)
• Saved to the Files app or cloud storage services you choose
• Deleted at any time through the app or iOS file management

Encryption

When you enable encryption for backups:

• We use AES-256 encryption, a military-grade encryption standard
• Your password is never stored by the app
• Encrypted backups can only be decrypted with your password
• If you forget your password, encrypted backups cannot be recovered

Biometric Security

When you enable Face ID or Touch ID:

• Biometric authentication is handled entirely by iOS Secure Enclave
• We never store or have access to your biometric data
• Authentication is used only to protect access to encrypted backups

5. Third-Party Services

ContactVault does not use any third-party services.

• No analytics services (Google Analytics, Firebase, etc.)
• No advertising networks
• No crash reporting services
• No social media integrations
• No payment processors (one-time App Store purchase only)

6. Permissions

ContactVault requests the following permissions:

Required Permissions:

• Contacts: Required to read your contacts for backup and restore functionality. All contact access is local only.

Optional Permissions:

• Face ID / Touch ID: Optional, used to authenticate before accessing encrypted backups. Biometric data never leaves your device.
• Notifications: Optional, used to send backup reminders if you enable them. You can disable notifications at any time in iOS Settings.

7. Data Sharing

We do not share your data. Because we don't collect or store your data on external servers, there is nothing to share.

When you choose to share backup files:

• Sharing is handled by iOS system sharing mechanisms
• You have complete control over what, when, and how you share
• We have no access to or knowledge of your sharing activities

8. Children's Privacy

ContactVault does not knowingly collect information from children under 13. Our app:

• Does not require any personal information to function
• Does not create accounts or profiles
• Does not collect any data from users of any age

9. Data Retention

Backup files are retained on your device until you choose to delete them. You have full control:

• Delete individual backups through the app's History tab
• Delete all app data by removing the app from your device
• Manage backup files through the iOS Files app

10. Your Rights

Because ContactVault processes everything locally and doesn't collect your data:

• Access: All your data is already on your device, accessible through the app or Files app
• Deletion: Delete backups anytime through the app or iOS file management
• Portability: Export backups in standard formats (VCF, CSV) that work with any system
• Control: You have complete control over your data at all times

11. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. When we make changes:

• We will update the "Last updated" date at the top of this page
• We will notify you through the app if significant changes are made
• Continued use of the app after changes constitutes acceptance of the updated policy
