No Trace vs Kivo Messenger

Encrypted code-based chat. No phone. No email. No account. Share an 8-character code with someone. They type it in. You are talking. End-to-end encrypted from your device. Nothing to log in to. Nothing to back up. WHY NO TRACE WORKS • No phone number — no SMS confirmation that fails in your country. You install, you chat. • No email — no recovery flow you have to remember. • No account — no profile, no friend list, no directory. • 8-character code — share on paper, by voice, by QR. Whoever has the code joins. Whoever does not, never sees the room. • Optional 2-layer code — share a room without leaking access. The join-code is the second gate. • Three privacy presets — Ghost saves nothing on your phone, Balanced keeps codes for one-tap re-open, Comfort keeps history too. Change anytime. • Screen-recording lock — your chats render as black in screen recorders. • App lock — optional tap-code on every launch. • 1-tap delete all data — Settings > Account > Delete. Nothing kept on our side. HOW IT IS DIFFERENT Signal needs a phone number. Telegram needs a phone number. WhatsApp needs a phone number. Threema gives you a permanent ID that lives forever. No Trace gives you a throwaway 8-character code per room — no identity follows you. WHO PICKS IT • Journalists collecting tips • Lawyers and doctors with confidentiality duties • Activists and advocates • Two people who want a chat that does not sit in either phone's backup • Teams who want a side channel separate from work tools CROSS-DEVICE iPhone, iPad, Web, macOS, Linux. Open the room on whatever you have nearest. PRIVACY YOU CAN VERIFY • No ads • Tracking limited to crash + basic analytics, disclosed in our privacy policy • Premium uses Apple Pay only — no external payment links • Delete all your data anytime: Settings > Account > Delete CONTENT SAFETY We have zero tolerance for objectionable content and abusive users. Every message can be reported with one tap (long-press > Report) and is reviewed within 24 hours. You can block any sender locally on long-press. Senders flagged for objectionable content are removed and ejected. Contact: hello@teamzlab.com.
