Secure messaging is about much more than end-to-end encryption. Metadata collection, open-source transparency, independent audits, default encryption, account requirements, backups, and jurisdiction all influence how private a messaging platform actually is. This comparison examines the major privacy-focused messaging apps and discusses the trade-offs each one makes instead of trying to crown a single “best” option.
