Everything here is end-to-end encrypted, including the parts most messengers treat as metadata.
Text, replies that quote from your own copy, emoji reactions, editing with an honest "edited" marker, delete for everyone, and forwarding.
Record and play voice messages. Audio is captured and played back in memory — plaintext audio never touches your disk.
Attachments are encrypted under a per-file key and streamed in uniform chunks, in direct chats and in groups.
Text, attachments and voice notes. No group key to leak: every message is encrypted separately to each member.

Search your history locally. Cells stay sealed on disk and are decrypted only in memory; a hit opens the chat at the matched message.
Require a fingerprint, face or your device PIN to open Z, and again after a chosen time in the background. On Android the key is bound to the hardware keystore.
Follows your system, or pick one. Every text and background pair in both palettes clears WCAG AA contrast, checked automatically.
