Why Tacq doesn’t ask for your phone or email

When you sign up, Tacq asks for no phone number, no email, no real name. Your account is an anonymous Master ID generated on your device.

What this gives you:

• you can’t be found by number or scraped into a spam database;
• your most sensitive detail — your number — never enters the system, so it can’t be stolen, handed to a stranger, or sold;
• the other person sees only the nickname you chose, not your real details.

What to understand about storage and encryption:

• by default, messages and media are stored on our servers (Google Firebase) and protected by access rules — technically, the server can read them;
• for anything especially private there are secret modes for one-to-one chats: “Secret” — end-to-end encrypted (the server sees only ciphertext), “Top secret” — the content never passes through the server and is delivered straight to the other person. See the “Secret messages” article;
• calls work differently: audio and video travel directly between devices (WebRTC) and are end-to-end encrypted; a call is not recorded or stored. Even when a relay server is used for difficult networks, it passes already-encrypted data and cannot read it;
• overall, Tacq is about data minimization: we don’t collect what could identify you.
