A private messenger should be evaluated through real conversations and a lost-device scenario. SimpleX Chat uses invitation-based connections rather than a permanent public user identifier, so onboarding and recovery deserve special attention.
Connect two disposable accounts using the SimpleX guide. Exchange text and media, add a group, and test a user changing devices. Review the data-management guide before exporting a chat database: set and safely store a database passphrase, then restore to a fresh device.
Compare alternatives on message delivery over poor networks, accessibility, contact discovery, and how much explanation a new participant needs. Avoid using real sensitive conversations until backup and recovery are understood. Privacy properties are useful only when people can reliably reconnect and retain the data they intend to keep.
