Secure Password Manager description

SPM has no back doors. No cloud interaction. Double AES256 encryption. Kept simple and small. Can export passwords to a password protected zip file. Copy password to clipboard function with the clipboard being cleared after a specific amount of time.
Why did I make this? A "secure" password manager on the play store that I was using, backed up my passwords to a cloud service. That service was hacked and all my passwords (that were supposed to be encrypted) were compromised. This is my solution.
