We're doing our best to deliver on our promises. Bugs happen. If you want to use us without an account you are free to do so. Or you are also free to use another service if you no longer trust us. We make mistakes. Period.
We are also ideating on a lot of other ways we can provably deliver ultimate privacy such as storing user chats encrypted on nostr relays or other some such ideas, but those are steeper engineering challenges that will take time.
If you have any other ideas on how we can architect things better we are all ears.
