- Signal saves sensitive information permanently in account databases, including phone numbers and group metadata.
- Deleting groups or chats only hides information; full deletion requires deleting all app data and re-registering without PIN.
- Signal uses SMS authentication, making accounts vulnerable to takeover through SIM swaps or SMS interception.
- ACIs (Account Identifiers) are tied to phone numbers and can be shared with governments upon request.
- Signal is centralized, runs on major tech servers, and can be censored or shut down by governments.
- Alternatives like Cwtch, Briar, and Delta Chat offer better metadata resistance and no phone number requirements, but have limitations.
- Recommendations for Signal users include using virtual numbers, GrapheneOS, encryption, and avoiding sensitive activities.
