Need a secure way to store user data which needs to converted back into original form using secret-key cryptography

HiI am building an app that needs to store anonymous data.I am proceeding in the following way:Ask user for password.Hash Salt Store using bcrypt.Encrypt data using password. What is a good way to encrypt the user data ?Since I am not storing the password I am thinking I could use crypto's inbuilt AES method without iv.The data to encrypt will be ranging from 10-100 chars. Will my method be safe enough ?
