Lock

With Lock, you can encrypt and hide any file effortlessly and securely, making it an ideal choice for protecting and sharing personal files like photos and videos. As a free Android app, Lock offers a seamless experience with no ads interrupting your workflow. The clean and simple design ensures ease of use while maintaining robust functionality. Additionally, it incorporates a secure gallery for viewing protected photos and videos, and it does not appear in the 'recent apps' list, preserving your privacy.

Advanced Encryption for Safety

Lock employs AES 256-bit encryption, recognized as a national standard in the United States, to ensure the utmost security for your data. This high-level encryption makes it nearly impossible for unauthorized access through brute force attacks, thereby safeguarding your information for millions of years. Users unfamiliar with encryption can feel secure knowing their data is well-protected without any complexity. The app's use of this advanced technology exemplifies its commitment to providing reliable security.

Minimal Permissions for Privacy

Lock stands out by requiring only one permission: access to external storage (SD Card) to encrypt your files. It does not have connectivity to internet, SMS, or other networks, eliminating any risk of your data being transmitted outside your device. The app’s presence on GitHub provides transparency, allowing users to review the source code themselves.

Effortless File Sharing

Sharing encrypted files is straightforward with Lock. Simply open the file and utilize the share icon within the app's file viewer to send your securely encrypted data. This feature enhances convenience while maintaining the security of your private information.
