I would trust them but I don't take the risk of "trust". There could be always issues which are out of your or the Password Managers control, e.g. crypto issues and also long term issues like quantum computing.

Due to this, I keep all of my passwords offline, as far as possible. For mobility and comfort reasons, I developed Authorizer (https://github.com/tejado/Authorizer):

"A Password Manager for Android with Auto-Type over USB and Bluetooth, OTP and much more.

The idea behind Authorizer is, to use old smartphones as a hardware password manager only. To avoid manual typing of long and complex passwords everytime you need them, Authorizer provides Auto-Type features over USB and Bluetooth. It pretends to be a keyboard (e.g. over an USB On-The-Go adapter) and with a button press inside the app, it will automatically type the password for you on your pc, laptop, tablet or other smartphone."
