Private keys for secret chats are only stored on the two participating devices.

As for server code — open sourcing the server code wouldn't really do much to improve trust. You would still have to trust us that we are using THAT code, not something different.

Depending on your definition of "decentralised", open sourcing the code would enable other people to set up servers that they can trust is running that code.

"... open sourcing the server code wouldn't really do that much to improve trust."

It would allow people to run your code (if they like it) on their own servers. Then they wouldn't need to trust you.
