Krypta Chat vs Doma

Krypta Chat is a private messenger with end-to-end encryption. No phone number, no email, no trackers, no ads. If you like, Krypta opens as a fully working calculator, and only your secret code opens your chats. NO PHONE NUMBER, NO EMAIL You don't need an account with your name. Krypta creates an anonymous ID; you add contacts by QR code or ID. Strangers can only send you a request that you have to accept. A CALCULATOR WITH A SECRET (OPTIONAL) During setup you can disguise Krypta as a calculator that really calculates. Your own secret code followed by "=" opens your chats. A separate erase code deletes everything instantly if you ever need it. DELIVERED WITHOUT A TRACE Every message is end-to-end encrypted: only you and the person you write to can read it, not the server and not us. Messages are deleted from the server as soon as your contact has received them. Disappearing messages, delete after reading, view once and password-protected messages let you decide how long something exists. EVERYTHING A MESSENGER NEEDS • One-to-one and group chats • Photos, videos, voice messages and files, encrypted • Replies, reactions, editing, search, mute, pin, archive • Notifications show who wrote, never what they wrote PROTECTION FOR YOUR IPHONE • Face ID and an additional vault password • Emergency button deletes everything instantly if you choose • Automatic erase if you don't open Krypta for a period you choose • Protection against screenshots and screen recordings VERIFIABLE SECURITY X3DH and Double Ratchet, XChaCha20-Poly1305, Argon2id.

Doma is a private messenger for exactly two people — you and your partner, in one shared home. One of you creates the home and shows a QR code. The other scans it, with the camera or from a screenshot, and you're connected. No sign-up, no phone numbers, no accounts. EVERYTHING YOU NEED, NOTHING YOU DON'T • Messages, photos and videos • Voice messages with an on-device transcript • Send your location, or share it live for one hour • Edit or delete your messages for both of you • Delivered and read ticks • Turn any message into a reminder, a note or a calendar event PRIVATE BY DESIGN • End-to-end encrypted: messages, photos, voice and location are encrypted on your iPhone with a key that only your two devices have. • Stored in your own iCloud. We run no servers and cannot read anything you send. • Notifications just say "New message in Doma" — never the content. • No ads, no tracking, no analytics. • Either of you can disconnect at any time. Doma is made for couples who want one quiet place for the two of them.
