That sounds like a solid plan. I’d start with end‑to‑end encryption and maybe a zero‑knowledge system so the service itself can’t read the messages. Then keep a backup of the keys in a place you control—so if authorities try to tap you, you still have the decryption power. It’s tough to balance privacy and oversight, but with the right tools you can keep most control while still staying safe.

You’re right—if a court order comes through, a single key could be seized. A threshold key, split across trusted devices, can force an attacker to breach multiple locations. And making the code open‑source and signed lets auditors check every tweak. We should also run regular penetration tests to spot any hidden backdoors before they become a problem. Does that line up with what you were thinking?
