Terms of Service

ZAHN UK Management Ltd  ·  Last updated 20 October 2026

Important safety information. ZAHN is not an emergency service. Nobody at ZAHN, and no emergency service, watches the app, your location, your check-ins or your reports. If you or someone else is in immediate danger, call 999 (or your local emergency number outside the UK). For non-emergencies in the UK, call 101. Never rely on ZAHN as your only way of staying safe.

Key points in plain English
  • You must be 13 or over to use ZAHN. If you are 13 to 15, you must tell a parent or guardian that you use it.
  • Only add people you know and trust in real life to your Bubbles.
  • The Safety Score is for general guidance only. It is not an official rating, and it cannot tell you that a place is safe.
  • Reports must be honest and about places and incidents, not about named or recognisable people. We can remove reports and suspend accounts.
  • You can complain, and you can appeal if we remove your content or restrict your account.
  • Nothing in these terms takes away your legal rights as a consumer.

Who can use ZAHN

  • You must be at least 13 years old.
  • If you are 13, 14 or 15, you must tell a parent or guardian that you use ZAHN and show them these terms. If you are under 18, we recommend that you go through the app with a parent, guardian or trusted adult.
  • When you sign up, we ask for your date of birth. You must give your real date of birth. We may ask for further proof of age if we think a user may be under 13. If we find that a user is under 13, we will close the account and delete its data.
  • ZAHN is available worldwide, except in Afghanistan. Some features work only in some places. For example, the Safety Score covers England only (see section 6).
  • You must not use ZAHN if we have previously banned you.

Your account

  • You sign up with your mobile phone number. We send you a one-time code by SMS to check the number is yours. Never share your codes with anyone.

  • Your account is for you alone. Do not let anyone else use it, and do not pretend to be someone else.
  • Your username is shown to other users. It must follow our Community Guidelines and must not include your full name, address or school if you are under 18.

What ZAHN does

ZAHN currently includes the following features. Features may change over time (see section 15).

  • Bubbles: private groups of people you choose. People in a Bubble can see each other's live location on a shared map, together with battery level, when the location last updated and the Safety Score of the area each person is in.
  • Ghost mode: pause sharing your location with one Bubble or with all of them.
  • Spots: saved places such as Home, Work or School. The people you choose are told when you arrive at or leave a Spot.
  • Location history: the people in your Bubbles can see the places you visited over the last 7 days, with times and durations, while you share your location with them.
  • Live journeys (Share ETA): share a trip and your expected arrival time so people in your Bubble can follow along. Sharing ends automatically when you arrive.
  • Check-ins: ask someone "are you OK?" in one tap. They can reply in one tap or mark their reply as urgent.
  • Search: search for places, addresses, areas and postcodes and see their Safety Score.
  • Safety Score and hotspot map: a score and map layer that summarise reported crime in an area (see section 6).
  • Reports: tell the community about an incident, by voice or by choosing a category, with a photo if you like. You can also post a report about a missing person or pet. Others can confirm whether it is still there (see section 7).

Using location features responsibly

  • Location sharing only happens with people you add to a Bubble, and only while you choose to share. You can use Ghost mode or turn off location permission at any time.
  • Only add people you know and trust in real life. Never accept a Bubble invitation from a stranger.
  • You must never use ZAHN to track, monitor or control anyone without their knowledge and free agreement. This includes partners, ex-partners, family members and children. Covert tracking, stalking and controlling behaviour can be crimes, and we will close accounts used in this way and may tell the police.
  • Location can be late, wrong or missing. This can happen because of signal, GPS, battery saving, phone settings or our providers. A person's last known location may not be where they are now.
  • We cannot guarantee that anyone sees a location share, Spot alert, check-in, journey or notification, or that they will act on it.

The Safety Score and hotspot map Key

For general guidance only. Not an official rating. Always use your own judgement. Source: police.uk

  • The Safety Score is a whole number from 1 to 10 that summarises reported crime in an area compared with other areas in the same region. A higher score means less reported crime. The hotspot map shows where reported crime is concentrated.
  • The score is worked out by ZAHN from police-recorded crime data published on data.police.uk. We update it monthly, using the latest three months of published data. Police data is usually published two to three months after the events, so the score does not reflect recent events. It is not produced, checked or endorsed by the police or any public body.
  • It only reflects crime that was reported to the police and published. Police data is published about a month after the end of each month, uses approximate locations on purpose and covers a rolling three-month period. Much crime is never reported. The score can be out of date and cannot reflect what is happening right now.
  • The score describes areas. It does not describe, and must not be used to make judgements about, any person, household or business.
  • A high score does not mean a place is safe, and a low score does not mean you will come to harm. Always use your own judgement, think about the time of day and your own situation, and call 999 (or your local emergency number outside the UK) in an emergency.
  • The score currently covers England only. Elsewhere, we show that the area is not yet covered. Where there is not enough data, we show "No data available" or "Limited data" instead of a score.
  • You must not copy, scrape or resell Safety Scores, or use them for commercial purposes, without our written permission.
  • More detail is in our Safety Score and Data Sources Notice.

Reports Key

What reports are

A report tells other ZAHN users about an incident or hazard at a place. You can make a report by choosing a category or by saying what happened in your own words. If you use your voice, your phone turns your words into text, and we use an AI service to suggest the right category. You choose the final category before you post.

Where reports appear

  • When you post a report, its location is pinned automatically to where you are, unless you move the pin. Pick the location of the incident, not your home or another private address.
  • Reports are shown on the map to other users.
  • Reports stay on the map for a limited time, up to 7 days depending on the type of report, then disappear from the map. We keep a record for longer, as explained in our Privacy Policy.
  • Other users can mark a report as "still there" or "looks clear". You can delete your own reports.

Anonymity

You can choose to post a report anonymously or under your username. If you post anonymously, other users cannot see who made the report. ZAHN can still link the report to your account. We may use that link to deal with misuse, to respond to a valid legal request, or to share information with the police where there is a risk of serious harm (see section 17).

Your promises when you report

  • Your report is honest and describes something you saw, experienced or reasonably believe happened.
  • You describe places and incidents only. You do not name, describe or identify any person, vehicle, home or business, and you do not include anyone's personal details. The only exception is a missing person report (see below).
  • You do not make false, exaggerated, malicious or joke reports, including reports aimed at harming a business, a neighbour or anyone else.
  • You do not use reports to share content that is illegal, hateful, threatening, sexual or graphic.
  • A report on ZAHN is not a report to the police. If a crime has happened, please also report it to the police (in the UK, on 101 or online), or call 999 (or your local emergency number outside the UK) in an emergency.

Making false reports, or reports that identify people, may break the law (for example the law of defamation, harassment or data protection), and you may be personally responsible.

Photos

  • You can add a photo to a report. Only add photos you took yourself or have the right to share.
  • Do not include people's faces, car number plates or the inside of anyone's home, except the photo of the missing person or pet in a missing person or pet report.
  • Do not post graphic, violent, sexual or humiliating images.

Missing person and pet reports

  • You can post a report about a missing person or a missing pet. It may include a description and a photo, so others can help look.
  • Only post a missing person report if you are the person's family member, guardian or carer, or you have their family's permission.
  • A ZAHN report is not a police missing person report. If someone is missing, especially a child or someone who may be at risk, call 999 (or your local emergency number outside the UK) first.
  • Include only what is needed to help find them. Do not include their home address, medical details or other private information.
  • Delete the report as soon as the person or pet is found. We may remove a missing person report at any time, including if the person or their family asks us to.
  • Missing person and pet reports stay up for 7 days and then expire. If the person or pet is still missing, you can post a new report. Our team is alerted to new reports and can review or remove them.

Accuracy

Reports come from users. We do not check every report before it appears, and we cannot promise that any report is accurate, complete or current. Treat reports as information to help you think, not as fact.

  • post or share anything illegal, including threats, hate, terrorism content, child sexual abuse material, intimate images without consent, or content that encourages self-harm;

How we moderate content Key

  • You can tell us about a report or a user that you think breaks the law or our rules by emailing support@zahnapp.com. Anyone can report content they think is illegal, even if they do not have an account.
  • We aim to review what you tell us within 24 hours. We deal with anything about risk of harm to children or immediate danger first.
  • We use a mix of automated tools and people to check content. Our automated tools include limits on how many reports one account can post, and community votes ("still there" or "looks clear") that help show whether a report is still accurate. Our team is alerted to new reports. Decisions to remove content or restrict an account are made by a member of our team.
  • If content breaks the law or our rules, we may remove it, limit who can see it, add a warning, suspend features, or suspend or close the account. We decide what to do based on how serious the problem is, whether it has happened before, and the risk to others.
  • We will tell you if we remove your content or restrict your account, and why, unless the law or safety reasons stop us.
  • Appeals. If you think we got it wrong, you can appeal within 14 days by replying to our message or emailing legal@zahnapp.com. A different member of the team will look at it and we aim to reply within 5 working days. If we agree we made a mistake, we will restore your content or account.

Complaints Key

  • You can complain to us about anything to do with ZAHN, including content you think is illegal or harmful, how we handled something you told us about, how we apply these terms, or our age checks. Email legal@zahnapp.com.
  • We will acknowledge your complaint within 5 working days and aim to resolve it within 30 days. We will tell you the outcome and what you can do next.
  • If your complaint is about your personal data, you can also complain to the Information Commissioner's Office (ico.org.uk, 0303 123 1113).
  • If you are not happy with our answer, you can take the matter to court (see section 19).

Your content and our licence to use it

  • You own the content you post, such as reports, your username and your profile photo.
  • You give us a non-exclusive, royalty-free, worldwide licence to host, store, display, adapt (for example to resize images or turn voice into text) and share your content in order to run, improve and promote the safety features of ZAHN. This includes showing your reports to other users and using reports, in anonymised and combined form, to show trends and statistics. The licence ends when your content is deleted, except for copies we must keep for legal or safety reasons and for anonymised statistics.
  • You confirm that you have the right to post your content and that it follows these terms.

Changes to ZAHN and to these terms

  • We are always improving ZAHN. We may add, change or remove features. If a change has a significant negative effect on you, we will try to tell you in advance.
  • We may update these terms to reflect changes to ZAHN or the law. We will tell you about important changes in the app or by email at least 30 days before they take effect, unless the change is needed urgently for legal or safety reasons.

Ending your use of ZAHN

  • You can stop using ZAHN at any time. You can delete your account in the app under Account > Settings > Delete account. Your account is deactivated straight away and deleted after a 30-day period, during which you can reactivate it.
  • We may suspend or close your account, or restrict features, if you seriously or repeatedly break these terms or the Community Guidelines, if your use puts others at risk, if we suspect you are under 13, or if the law requires it. Where possible, we will warn you first and explain why. You can appeal (see section 9).
  • We may stop providing ZAHN, or close an account for any other reason, by giving at least 30 days' notice.

Law enforcement and protecting people

We may share information about your account, including your location, reports and activity, with the police or other authorities if we are legally required to, or if we believe in good faith that it is needed to prevent death or serious harm, to protect a child, or to investigate serious misuse of ZAHN. Our Privacy Policy explains this.

Our responsibility to you

  • ZAHN is provided free of charge. We will provide it with reasonable care and skill, but we cannot promise it will always be available, error-free or accurate.
  • We are responsible for loss or damage you suffer that is a foreseeable result of us breaking these terms or failing to use reasonable care and skill. We are not responsible for loss or damage that was not foreseeable.
  • We are not responsible for decisions you make based on Safety Scores, reports, location information or alerts, or for the actions of other users, except where the loss is caused by our own breach of these terms or our negligence.
  • ZAHN is for personal use. We are not responsible to you for any business losses.
  • Nothing in these terms limits or excludes our liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, or for anything else that cannot be limited or excluded by law, including your rights under the Consumer Rights Act 2015.

Law and courts

These terms are governed by the law of England and Wales. You can bring legal proceedings in the courts of England and Wales. If you live in Scotland or Northern Ireland, you can also bring proceedings in your local courts, and the mandatory consumer law of where you live will still apply.

If any part of these terms cannot be enforced, the rest still applies. If we do not enforce our rights straight away, we can still enforce them later. Nobody else has rights under these terms, except Apple as set out in the EULA.
