Terms of Use

1. Acceptance of Terms

By downloading, installing, or using the Encrypt App ("the App"), you agree to be bound by these Terms of Use. If you do not agree to these terms, please do not use the App.

2. Description of Service

The Encrypt App is a file encryption application that provides military-grade security for your files. The App provides:

  • • RSA 2048-bit encryption with AES-256 hybrid encryption for files
  • • Local key pair generation and management
  • • File encryption for personal use or specific recipients
  • • File decryption using your private key
  • • Public key sharing and management for secure file sharing
  • • Private key export/import for cross-device compatibility

3. Security and Encryption Responsibilities

Important Security Considerations:

  • • You are solely responsible for protecting your private keys
  • • Loss of private keys means permanent loss of access to encrypted files
  • • The App uses industry-standard encryption but cannot guarantee absolute security
  • • You should backup your private keys securely
  • • Only share public keys with trusted recipients

User Responsibilities:

  • • Verify the identity of recipients before sharing encrypted files
  • • Keep your private keys secure and confidential
  • • Do not use the App for illegal activities or content
  • • Understand that encryption is not a guarantee against all security threats

4. Key Management and File Security

The App provides tools for managing encryption keys and encrypted files:

  • • RSA key pairs are generated locally on your device
  • • Private keys are stored securely using iOS/macOS keychain services
  • • Public keys can be shared with others for secure file sharing
  • • Encrypted files use hybrid encryption (RSA + AES-256)
  • • You can export/import private keys for device migration

The App does not validate the authenticity of public keys you import - you must verify their legitimacy independently.

5. Intellectual Property

All content, features, and functionality of the App, including but not limited to encryption algorithms implementation, user interface, and software, are owned by the App developer and are protected by copyright and other intellectual property laws.

Your Files and Keys: You retain full ownership of all files you encrypt and all encryption keys you generate. We do not claim any rights to your content or cryptographic keys.

6. Disclaimers and Limitations

Encryption Limitations: While the App uses industry-standard encryption, no encryption is 100% secure against all possible attacks or vulnerabilities.

Key Loss: We cannot recover lost private keys or decrypt files if you lose access to your keys.

File Integrity: While the App includes integrity checks, you should verify important files after encryption/decryption.

Technical Limitations: The App may experience bugs or compatibility issues, and we cannot guarantee perfect operation.

7. Limitation of Liability

The App developer shall not be liable for any direct, indirect, incidental, special, or consequential damages resulting from the use or inability to use the App, including but not limited to loss of files, compromise of encrypted data, or security breaches, even if advised of the possibility of such damages.

8. Export Control and Legal Compliance

The App uses encryption technology that may be subject to export control laws. By using the App, you agree to comply with all applicable laws and regulations regarding the use and export of encryption software.

You are responsible for ensuring your use of the App complies with local laws and regulations in your jurisdiction.

9. Changes to Terms

We reserve the right to modify these Terms of Use at any time. Updated terms will be posted within the App and on our website, and continued use constitutes acceptance of the revised terms.

10. Contact Information

For questions about these Terms of Use, please contact us through the App Store review system or the support information provided in the App.

2. How We Use Information

Local Processing Only: All file encryption, decryption, and key management operations occur entirely on your device using standard cryptographic libraries.

Temporary Processing: Files are temporarily accessed during encryption/decryption processes and immediately released from memory after completion.

Key Storage: Private keys are stored securely in the device's keychain and never transmitted or backed up to external services.

Contact Management: Public keys from contacts are stored locally to enable secure file sharing.

3. Data Sharing and Disclosure

No Data Sharing: We do not share, sell, rent, or disclose any file data, encryption keys, or personal information to third parties because we do not collect or store such data.

User-Controlled Sharing: The only way data leaves your device is when you explicitly share encrypted files or public keys through your device's sharing features.

No External Services: The App does not integrate with any external encryption services, cloud storage, or analytics platforms.

System Sharing: When you share files or keys, the sharing is handled by iOS/macOS system features and subject to Apple's privacy policies.

4. Data Security

Local Security: All sensitive data is protected by your device's built-in security features, including device encryption, biometric authentication, and system-level app sandboxing.

Keychain Protection: Private keys are stored in the iOS/macOS keychain, which provides hardware-backed security on supported devices.

Cryptographic Security: The App uses industry-standard encryption algorithms (RSA 2048-bit, AES-256) implemented through Apple's Security framework.

No Network Transmission: Since no data is transmitted over networks, there are no network-related security risks.

Memory Security: Sensitive data is cleared from memory immediately after processing to minimize exposure.

5. Children's Privacy

The App does not knowingly collect any information from children under 13. Since all data processing occurs locally on the device with no external data collection, there are no additional privacy concerns for younger users. Parents should supervise children's use of encryption software and key management.
