Read full description

TopSecret Chat is an advanced OTR (Off-The-Record) messaging application for untraceable communications, anonymous identity, and military-grade security. We are funded and resourced by the free and non-profit collaboration of volunteers in the non-governmental organisation Bona Fide NGO that is engaged in social impact missions. We believe that privacy is a universal right and that your data is nobody else's business. Our Confidential Computing technology with E2E (End-To-End) and Multi-Layer encryption makes your messages untraceable and impossible to retrieve even if your device falls in the wrong hands. TopSecret Chat never requires access to your device's storage or your contact details, on the contrary of other messaging Apps. Designed for classified communication: β€’ No phone number required. Choose between a fully Anonymous or Authenticated account β€’ Advanced OTR (Off-The-Record) instant messaging β€’ Ephemeral messages up to 30 days are protected also while in use by our Confidential Computing technology β€’ Your encrypted data and metadata stays in a volatile memory enclave and never stored on any device or server, not even temporarily β€’ Contacts on your device are never accessed β€’ No logging, tracing, scanning, sharing of your communications β€’ No ads or activity tracking TopSecret Chat is not to replace but complement other messaging apps when you need an extra security and full anonymity. Other messaging Apps allow unlimited messages because they store all your data somewhere, at least temporarily, on your device or in the Cloud... this may compromise your secrecy and identity because attackers can use forensic technology to retrieve your data and metadata, even if deleted, for example when your phone is hacked, seized, lost, stolen. With TopSecret Chat your messages are never stored on any device or server, not even temporarily, thanks to our Confidential Computing technology. The best way to ensure TopSecret Chat remains available and free is to make a donation. Donations are never linked to your TopSecret Chat account and can be anonymous. https://donorbox.org/topsecret-chat-en Follow us on Mastodon (@topsecret_chat), LinkedIn (@topsecret-chat), Facebook (@topsecret.chat), X / Twitter (@TopSecret_Chat) for the latest updates and announcements.
