"Sindiy" is an application for managing passwords. It is created focusing on the basic minimum functions of saving passwords, sorting, and managing passwords.(There is no dangerous function like copying the password to the cloud.)
No troublesome procedures such as user registration are necessary, so you can use it immediately after installation.
Since all saved passwords are encrypted, it is possible to reduce the possibility of password leakage when using iClouds backup function or even in the event of your iPhone(iPad) loss.
You can select "None", "TouchID", "Master Password" for authentication at application startup."Master Password" provides the most robust security environment, but you must enter the password each time the application is launched. On the other hand, "None" improves convenience but weakens security.
You can select the optimum method according to your own scene.
