Usage Manual

Chapter 1 Data Security

Data security is the primary concern of this software! In the design process, when we encountered a trade-off between safety and convenience, we chose safety without hesitation, rather than giving up convenience. So sorry that this software has many special designs that may not be so convenient to use.

1.1) Never save your password

Your password is only used once in the memory when you open the safe, it will not be saved in the mobile phone memory card, nor will it be transmitted over the network.

• Advantage: very safe! Even if all your data files are stolen and transmitted, no one can read their contents without the password.
• Disadvantage: Once the password is lost, all data in the safe cannot be recovered.

1.2) Encrypt each file individually

Adopt AES encryption commonly used in the industry, and use chain encryption to improve security. Encrypt with your password to get a long random key, and use this key and the random scrambling code of each file to decrypt each file individually.

• Advantages: very high security, no need to re-encrypt all files even if you change the password.
• Disadvantages: The developer works hard, and may lose hair.

1.3) The files are stored in the application space

The encrypted photo and video files are stored in the storage space of this application and cannot be accessed by other applications. Of course, some system applications can access these files, but because all content, including file names, are encrypted and saved, what the system applications see is just a bunch of garbled characters.

• Advantages: It fully complies with the latest specifications of the Android system, and encrypted files will not be deleted by cleaning software.
• Disadvantage: Deleting the app will lose all safes and all files inside the safe.

Chapter 2 Usage Skills

2.1) Password input

• Text password: You can enter any text including Chinese characters, but please note that the input method may read your password.
• Numeric Password: Can support up to 16 digits.
• Fingerprint unlock: the first time you must use the password to open the safe, and every time the safe is locked automatically, you can use your fingerprint to unlock it for easy use.

2.2) Batch import

When selecting files, long press to batch import photos and videos

2.3) Direct photo and video

Usually we take a picture with the system camera, then import it into the private album, and then delete the original photo. However, such an operation is still not safe enough, because after taking a photo with the system camera, the photo is saved in the system album, and there is a risk of being read by other applications or automatically uploaded to the cloud. If you have high privacy requirements, you can directly use the camera in the private album to take pictures or record videos.

• Current shortcomings: photos generated directly by taking pictures do not contain location information

2.4) Intranet quick transfer

• You can use the browser on your computer to open the safe, view your gallery and photo album on your computer, or upload photos directly from your computer.
• Uploaded photos and files can be encrypted and stored directly in the APP to ensure information security.
• Current shortcomings: The transport protocol is HTTP without encryption

2.5) Private Cloud Sync

• Sync to private cloud services, and store data under your own account. You have control of your own data.
• Optional automatic synchronization or manual synchronization
• Currently supported: Amazon Simple Storage Service (Amazon S3)
