Terms of Use

Version 2026-11-01 · Last updated: 1 November 2026

These terms are an agreement between you and the developer of mr.enzo — Garnik Papian, an individual based in Russia (“we”, “us”). By creating an account or using mr.enzo you accept them. Please read them together with the Privacy Policy.

1. Who can use mr.enzo

You must be at least 13 years old, and older if the law of your country sets a higher minimum age for using a service like mr.enzo (up to 16 in some EU countries). If you are under 18 — or under the age of majority where you live, if that is higher — you may use mr.enzo only with the permission of a parent or guardian. We do not ask for your age, and the birthday you may add to your profile is not used to check it. You may not use mr.enzo if we have previously banned you or if the law forbids you from receiving it.

2. Your account

• You sign in with an email address or, where the app offers it, a phone number, using a one-time code sent to it by email or by SMS. Use only an address or a number that is your own, and keep access to it: whoever receives your codes can sign in to your account unless your cloud password or two-step verification stops them. A mobile operator may give a number you no longer use to someone else. Keep your device and any cloud password or two-step verification codes safe. You are responsible for what happens in your account.
• Your username, display name, profile photo and bio must not impersonate another person or organisation or break the rules in section 3. A phone number and a date of birth in your profile are optional: add only your own, choose who sees them, and remove them whenever you like.
• You can delete your account at any time in the app (You → My Profile → Delete Account).

3. What is not allowed

You must not use mr.enzo to create, send, share or store, and you must not help anyone else to do so:

• sexual content involving minors, or any content that sexualises or endangers children;
• sexual content or intimate images of anyone shared without their consent;
• threats, harassment, bullying, stalking, or publishing someone’s private information without their consent;
• hate speech or content that attacks people because of their race, ethnicity, nationality, religion, disability, sex, gender identity, sexual orientation or similar characteristics;
• content that promotes terrorism, violent extremism, or serious violence, or that encourages suicide or self-harm;
• spam, scams, fraud, phishing, malware or deceptive links;
• illegal goods or services, or any other illegal content or activity;
• content that infringes others’ copyright, trademarks or other rights;
• impersonating other people or organisations, or misleading others about who you are.

You also must not: attack, overload, probe or disrupt our servers or the offline network; access accounts or data that are not yours; create accounts by automated means or in bulk; send messages in bulk to people who did not ask for them; or reverse-engineer the app in order to do any of these things.

Where we can see a breach, and where we cannot. One-to-one chats, group and channel posts, attachments, calls, push-to-talk and stories posted from app version 1.2.1 or newer are end-to-end encrypted: we cannot read them and do not monitor them, and we see a message or the text of a story only when someone attaches it to a report. What is stored without that encryption — and what we can therefore look at when we handle a report — is what is meant for other people to see: your profile (username, name, photo and bio; open to every user), stories posted from app versions before 1.2.1 (shown to the people with whom you have chosen each other), the name, description, photo and member list of a group or channel (shown to its members), and the sticker sets published in the public catalogue (open to every user wherever the app offers the catalogue).

4. Reporting, blocking and moderation

• Report. Use “Report” on a message, profile, group, channel, story or public sticker set; the app confirms that the report was sent. Because messages are end-to-end encrypted, we can only see the messages you choose to include in the report.
• Block. A blocked user can no longer send you messages, call you, see your stories or see when you are online.
• What we do. We review every report, usually within 24 hours. Depending on the case we remove the content we can access (for example profiles, group and channel information, stories and public sticker sets), warn the user, withdraw the right to publish sticker sets, remove them from a group or channel, or suspend or permanently ban the account, and we may block them from creating new accounts. When the law requires it — in particular for child sexual abuse material — we report the content and the account to the competent authorities.
• What we tell the person concerned. When we restrict or block an account, remove content or withdraw the right to publish sticker sets, we say what was done and why — by email to the address of the account, if it has one. We do not write to accounts that are plainly spam or were created in bulk.
• If you disagree. Write to ajkzantokaev@gmail.com from the address of the account (if the account has none, give its username) and explain why: we look at the decision again and reverse it if it was wrong.
• What the person who reported hears. We do not write to you about the outcome of a report on our own. If you want to know what was decided, write to us from the address of your account (if the account has none, give its username) and we will tell you whether we acted on your report.
• You can also report abuse by email to ajkzantokaev@gmail.com.

5. Your content

You keep all rights to the content you send. You give us only the permission we need to run mr.enzo: to store and transmit your encrypted messages and files, and to show your profile and stories to the people allowed to see them. You are responsible for the content you send and must have the right to share it.

5.1 Public sticker sets

Stickers you make and send in chats are ordinary encrypted attachments. Publishing a set in the public catalogue is separate and optional, and these additional rules apply to it:

• It is public. A published set — its pictures, its title and, only if you turn it on, your name and username — is stored on our server without end-to-end encryption and shown to users of the app. Before each publication the app shows you the publishing rules and asks you to confirm them.
• Only your own work. You must have made the pictures yourself or hold every right needed to publish them. Besides everything listed in section 3, a public set must not contain other people’s characters, logos, brands or artwork; photographs or recognisable likenesses of real people; nudity or sexual content.
• Review before publication. We look at every set and every update before it becomes public and may refuse it, with a reason. Approval is not an endorsement and does not move responsibility for the set from you to us.
• Licence. You keep your rights. You give us a non-exclusive, royalty-free, worldwide licence to store, reproduce, resize and distribute the set inside the app for as long as it is published. People who already added a set keep their copy after you unpublish or delete it.
• Reports and removal. Anyone can report a set. A set that breaks these terms is removed from the catalogue and from the devices it was added to. An account that publishes infringing or prohibited sets repeatedly loses the right to publish, and may be suspended or banned (section 4).
• Copyright and other rights. If you believe a set infringes your rights, write to ajkzantokaev@gmail.com with a link to the set, a description of the work or right concerned, and your contact details. If your set was removed and you believe that was a mistake, send your objection, with your reasons, to the same address; we will look at it again and restore the set if the removal was wrong.

6. How the service works

• Offline network. Without the internet, messages can travel between nearby devices over Bluetooth and Wi‑Fi and be carried by other people’s devices. Delivery depends on who is nearby and is not guaranteed. While the offline network is on, nearby devices see a random code that changes from time to time, not your name or your account. Between phones with app version 1.2.3 or newer, the frames of the offline network are sealed: the devices that pass them on see neither the sender nor the recipient. A frame to a phone with an older version still carries your numeric account ID and your public signing key, so that the devices passing it on can check it is genuine. The exception is the People Nearby screen: while you keep it open, the phones nearby see your username, display name and numeric account ID (Privacy Policy, 2.6). By using the offline network you agree that your device works in it as a relay and a courier: it carries and passes on other people’s encrypted messages, which it cannot read, and when it has internet access it hands them to our server for delivery. From app version 1.3.0 this cannot be turned off on its own — only together with the offline network; a phone in relay mode does the same. The messages of an account that hides its sender in notifications are never couriered.
• Push-to-talk is off until you switch it on. Speaking works only between two people who have each added the other as a contact, while both have it on; such a contact can also ring you while yours is off, and answering the ring turns it on. It depends on Apple’s Push to Talk service and on both phones being reachable; a transmission that nobody receives within a few minutes is lost.
• Translation and turning voice and video messages into text are done by iOS on your device. They can be wrong or unavailable for a language; do not rely on them where accuracy matters.
• No emergency calls. mr.enzo is not a replacement for a phone service and cannot be used to call emergency services. In an emergency, use your phone’s regular calling.
• Free service. mr.enzo is free. We may add, change or remove features, and we do not promise that the service will always be available or error-free.

7. Ending the agreement

You can stop using mr.enzo and delete your account at any time. We may suspend or delete your account if you break these terms, if the law requires it, or to protect other users or the service — in urgent cases without warning you first. What we tell you and how to object is in section 4.

8. Disclaimers and liability

mr.enzo is provided “as is” and “as available”. To the extent permitted by law, we give no warranties, and we are not liable for indirect or consequential losses, for lost data or messages, or for content sent by other users. Nothing in these terms limits liability that cannot be limited by law or your mandatory rights as a consumer.

9. Apple

If you downloaded mr.enzo from the App Store, Apple’s Standard Licensed Application End User License Agreement also applies to your licence of the app. These terms are between you and us, not Apple. Apple is not responsible for mr.enzo or its content, for maintenance or support, or for any claims about the app; we are. Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them. You confirm that you are not located in a country subject to a U.S. Government embargo and are not on any U.S. Government list of prohibited or restricted parties.

10. Changes

We may update these terms. The new version is published on this page with a new date and version number, and the History below says what changed. An important change is published on this page before it takes effect, with the date from which it applies. If you keep using mr.enzo after a change takes effect, you accept the updated terms; if you do not agree, you can delete your account.

History

• 1 November 2026 (version 2026-11-01). Section 6, “Offline network”: by using the offline network you agree that your device works in it as a relay and a courier; from app version 1.3.0 this cannot be turned off apart from the offline network.
• 28 October 2026 (version 2026-10-28). Brought in line with app version 1.2.5. Section 2: where the app offers it, you can sign in with a phone number and a code sent by SMS; you are responsible for keeping access to the address or the number you sign in with. Section 3: stories posted from app version 1.2.1 or newer, and push-to-talk, are end-to-end encrypted. Section 4: an account without an email address objects, or asks what was decided on its report, by giving its username. Section 6: between phones with app version 1.2.3 or newer the frames of the offline network are sealed and do not carry your account ID; the People Nearby screen; the push-to-talk ring; turning video messages into text.
• 9 October 2026 (version 2026-10-09). Added to section 4: what we tell a person whose account or content we restrict, how to object, and what the person who reported hears. Added to section 3: what is end-to-end encrypted and what is not. Section 1: the parent’s permission is needed under 18. Section 6: what the frames of the offline network carry. “Within 24 hours” became “usually within 24 hours”. The notes “from version 1.1” were removed from the text.
• 5–8 October 2026. Several editions; the last of them covered app version 1.1: public sticker sets (5.1), push-to-talk, couriers and relay mode in the offline network, translation and voice-to-text, the optional phone number and birthday in the profile. These editions also named the developer.
• 28 September 2026. First version.
