Enter your email address and we send a 6-digit code to it; enter the code in the app. There is no password to remember. Where the app offers sign-in by phone number, you can enter your number instead and get the code by SMS. If you turned on a cloud password or two-step verification, the app asks for it after the code. A new account is created the first time you sign in with an address or a number — so sign in the way you did before: an account created with an email address is reached by that address, not by a phone number.

• Check the Spam and Promotions folders; the email’s subject starts with the code itself, for example “123456 is your mr.enzo verification code”.
• Make sure the address is spelled correctly.
• A code is valid for 10 minutes. You can ask for a new one, up to 5 times in 10 minutes.
• Still nothing? Write to us from that address.

Search by username, name or, where the app offers it, phone number. If you allowed access to Contacts, the app, where it offers this, finds by itself which of your contacts are already on mr.enzo and shows them in the Contacts tab: numbers reach the server only blinded, and your address book itself never does. To turn this off, take away mr.enzo’s access to Contacts in iOS Settings → mr.enzo. Where there is no automatic check, tap “+” in the Contacts tab and “Find Friends from Contacts”. You can also add someone in person by scanning the QR code on their screen.

Hold the microphone button and speak: release and the message is sent. Slide up to lock the recording and take your finger off; slide left to cancel. Release in under a second and nothing is sent. A quick tap, as before, starts a recording that you send with the button. A video message works the same way: hold the camera button (up to 60 seconds); a tap on the camera button still opens the camera.

It is in the You tab → Privacy, and is on by default. Turn it off and your phone no longer tells people in one-to-one chats that you read their messages, and their “read” marks show to you as “delivered”. It works both ways: you do not see others’ receipts either. Groups and channels have no read marks.

Yes, where the app offers it: enter your number on the sign-in screen and we text you a code; signing in by email stays. An account created with an email address is reached by that address, not by a number. If a number has not been used to sign in for a long time, the app asks whether the account is yours: “It’s my account” or “Create a new account” — in that case the old account loses the number.

Where the app offers sign-in by phone number: the You tab → My Profile → Phone number. Change Number: the new number is confirmed with an SMS code, your chats, groups and contacts stay; if your contacts can see your number, the app offers to tell them the new one. Delete Number is available when the account has an email address to sign in with (otherwise the app offers to add one); a code confirms it. The app also offers to confirm, with an SMS code, a number that an older version saved without confirming it.

Yes. Chats, group and channel posts, attachments and calls are end-to-end encrypted: only the people in the conversation can read or hear them, not us. To make sure nobody is in the middle, compare the safety number with your contact in the chat menu.

Not end-to-end encrypted — because it is meant for others to see or because we need it to run the service:

• stories posted from app versions before 1.2.1, and a sticker set you publish in the public catalogue;
• your profile: username, name, photo and bio;
• the name, description, photo, member list and roles of a group or channel;
• the messages you attach to a report.

To deliver messages and calls our server also necessarily sees who contacts whom, when and how much — not what. The details are in the Privacy Policy, section 2.

When there is no internet, iPhones with mr.enzo nearby can pass encrypted messages to each other directly over Bluetooth and Wi‑Fi — no mobile network or Wi‑Fi router needed. If the recipient is not nearby, other mr.enzo users’ phones can carry the message along for up to 24 hours (“Pigeon Mail”); they cannot read it. A phone that carries your message and gets internet access can also hand it to our server, which delivers it like any other message (a “courier”).

• Keep Bluetooth and Wi‑Fi turned on (they do not need to be connected to a network) and allow Bluetooth and Local Network access for mr.enzo.
• It works best between people who have already chatted in mr.enzo, so their phones know each other’s encryption keys. You can exchange keys in person, without the internet, with the QR code on the offline network screen; the very first message to a new contact still needs the internet once.
• iOS limits background radio use, so keep the app open when you rely on the offline network.
• In the You tab → Offline Network you can choose Auto, Always or Off. Nearby devices do not see your name: the radio shows a random code that changes from time to time. Between phones with app version 1.2.3 or newer, the frames of the offline network are sealed: the phones around see neither the sender nor the recipient. To a phone with an older version they carry your numeric account ID and your public signing key, so that the phones passing them on can check they are genuine. The exception is the People Nearby screen: while it is open, it shows your name to the phones nearby (Privacy Policy, 2.6).

• Push-to-talk: hold the button and speak to one contact; they hear you almost at once, also on a locked iPhone. Both of you must have added each other as contacts and switched it on. If the app says “Unavailable”, ask your contact to add you and to update the app.
• Translate (touch and hold an incoming message) and voice-to-text (on a voice or video message) run on your iPhone with iOS’s own tools. Nothing is sent to us. iOS may ask to download a language the first time, and not every language is supported.
• App lock and hidden chats are protected by a passcode that exists only on your iPhone. We cannot reset it for you.

You can make stickers from your photos and send them in chats; like photos, they are encrypted. Publishing a set in the public catalogue is optional: we review every set before it appears, and a published set is visible to other users. You can unpublish or delete your set at any time.

To report a set, open it in the app and choose Report. Without the app — for example if you are a rights holder — email ajkzantokaev@gmail.com with the link to the set (it looks like mrenzo.com/s/…) and tell us what is wrong. See the Terms of Use, section 5.1.

• Allow notifications for mr.enzo and check that Focus or Do Not Disturb is not silencing calls.
• Allow microphone access (and camera for video calls) in iOS Settings → mr.enzo.
• Update to the latest version of the app.
• On restrictive networks calls go through our relay server and may take a few seconds longer to connect.

Touch and hold a message and choose Report, or open a person’s profile and choose Report or Block. Groups, channels, stories and public sticker sets have Report in their menu. A blocked person can no longer message or call you, see your stories or see when you are online. We review every report, usually within 24 hours, and remove content and users that break the Terms of Use.

Open the You tab → My Profile → Delete Account and confirm by typing your username. Your account, profile, contacts, files, group posts, published sticker sets and waiting messages are deleted from our servers, and the app’s data is removed from your iPhone. This cannot be undone. What stays on the servers for a while after that is listed in the Privacy Policy, section 6. If you cannot open the app, email us from your account’s email address and we will delete it for you. An account that signs in with a phone number alone has no address to write from: sign in to it again with that number, on any iPhone, and delete it: the You tab → My Profile → Delete Account.

No. mr.enzo cannot place emergency calls. Use your phone’s regular calling in an emergency.

iPhone with iOS 18 or later.
