Because the software uses the Advanced Encryption Standard (AES) algorithm and is subject to the US Export Administration Regulations (EAR), you may not download or use PassKeyboard in a regulated country, including but not limited to Iran, Cuba, Syria, Sudan and North Korea.

A: Unlike most similar software, it only rudely stores the data in plain text, or simply encrypts it with the MD5 algorithm.
PassKeyboard uses military-grade PBKDF2 and AES encryption algorithms to protect your master password and store data. The cloud additionally uses Bcrypt and AES multi-layer security encryption, and the network
ansmission uses the HTTPS protocol.
Data is always kept secret, and even PassKeyboard engineers can never get your information.
Only you (using the master password) can decrypt and access your data locally on the device.
The brief process is as follows:

A: The master password is very important and is the only credential you can log in to PassKeyboard. It is also one of the variables that encrypt/decrypt your stored data.
We use the military-grade PBKDF2WithHmacSHA256 to perform tens of thousands of rounds of lossy encryption on the master password, get the "encrypted string" and store it, which means we won't record and upload your original master password (which is very dangerous behavior).
When the user logs in, the master password is entered, and the encrypted string encrypted in the same way is compared to verify the identity.
The "encrypted string" is lossy encryption, and the reverse master password cannot be reversed. That's why you forgot your master password and can't get it back. Please keep in mind, don't tell anyone.

A: Sorry, we can't help you find it.
If you still want to continue using your current account, you can email us at support@imuuzi.com for manual review and account cancellation.
You need to use the email address used for registration, send the application email.
We will reply you after processing, and you can re-register with your original email address.

A: WeChat quick login can only get the avatar and nickname that you publicly display, and you won't get the specific micro signal, binding mobile phone number, real name information, WeChat contact, etc. Please rest assured.

A: Off Set-encrypt cloud sync option, data is only stored locally and will not be uploaded to the cloud.
If you are afraid of secretly uploading data (we will not do this at all → _→), in order to dispel the concerns, you can manually disable the software networking permissions after the login authentication is successful, completely disconnected from the network. Only manually create and restore backup files.
Login is used to verify the validity period of the account, while ensuring that the local backup data can only be restored again in the same account.

A: After upgrading the Pro version, you will receive an exclusive gift code.
After sharing with friends, both parties can get a one-month Pro version, which can be accumulated.
Note: The gift code feature may not be available for iOS clients as required by the Apple App Store review.

A: If you do not renew your subscription before the end of your life, it will automatically drop to the free version, showing only the last 2 records.
The full record will be synchronized after the renewal.
If the overdue time is too long, such as more than 30 days, it may be cleared (not sold).

A: We sell excellent products and services at reasonable prices and maintain long-term operations. Gray revenues such as spam ads, sales of user data, and background wake-ups for other apps.

A: If you want to import the backup data of a password manager that is already in use to PassKeyboard, it cannot be imported because the encryption algorithm is different.
