Quicall vs Atom Messenger

We, humans, have natural ways to communicate. We say things to each other in private, then we forget over time. Quicall is here to do that digitally. Quicall is fully encrypted end-to-end. All your messages, whether it's a 1:1 chat or a group chat, are fully encrypted in-transit or at rest. Quicall does NOT store your messages, not on the server side, and not on the client side. You can choose to store messages for 1, 7 or 30 days. After which, the messages are gone. There are no permanent storage options. Quicall does not store metadata. Metadata often reveals more than the contents of the messages themselves. Quicall prefer not to know that. Once a message is delivered, no other info about the message is kept. Quicall does not require a phone number. You should be able to chat with others without disclosing your phone number. You can register on Quicall with an email address. And you can disable people's ability to find you by email. Quicall is not designed for viral growth. It is not easy for people to find you. You can invite or connect with friends with a unique link or QR code. Quicall is designed so that only your friends can find you. Quicall is open-source. We believe secure apps should be transparent in how they work. Quicall is free. No ads. Quicall does not collect or sell data.

Atom is the integrated messaging solution for organizations or individuals that require maximum security. The combination of Atom's proven security architecture and absolute data ownership create an independent chat environment that is unmatched in terms of confidentiality. PRIVACY AND ANONYMITY Atom is designed to generate the least amount of metadata possible without keeping conversations inside the phone. Each user is anonymous and registration takes place only through direct invitation from the administrator of the single node. SECURE ENCRYPTION Atom performs full end-to-end encryption of all communications exchanged. Only the intended recipient, and No one else, will be able to read your messages. Encryption keys are generated and securely stored on user devices to prevent copying or backdoor access.
