Your building. Your street. Your eyes.
Neighbours see what happens in their stairwell, their car park and their street long before anyone else. With LEON they share it in ten seconds, and the people moving in next year can see it too.
Know where you are putting your feet.
A flat is a decision for years. Before you sign a lease or a purchase, look at what neighbours and local news have reported around the address, and how the area compares with the rest of France.
The colour of an area
In France: official crime figures from the Ministry of the Interior, per commune, compared with the national rate. They show the long-term picture.
The dots on the map
What happened in the last 7 days. They show today, not a reputation.
Before you sign
- Visit the street twice: once in the day, once after 10 p.m.
- Walk through the car park, the cellars and the bin room.
- Check the entrance: entry code, intercom, a door that actually closes.
- Ask the caretaker or a neighbour what has happened this year.
- Ask the managing agent (syndic) for recent minutes mentioning break-ins or damage.
- Open the map at different times of the week, not only once.
Ten seconds, from your own front door.
Everyone in the building becomes the eyes of LEON. Nobody has to confront anyone: you report what you saw, from a safe place.
Open LEON, tap the red shield
The pin drops where you are. Move it to the right spot: the car park entrance, the corner of the street, the hall.
Choose what you saw
Break-in, forced door, vandalism, a fire, drug dealing, harassment. Add a photo only if you can take it without being seen.
Your neighbours are warned
Once a second person confirms it, or our team does, LEON users within 3 km get an alert if it happened less than two hours ago.
Anonymous on the map
The map shows what, where and when, never who. For burglaries and sexual violence the point is moved by about 300 m so that no flat or victim can be identified.
Moderated
Photos are checked by our team, with their location data removed, before anyone sees them. Any report can be flagged; after three flags it is hidden until we review it.
Facts, not people
Report events, not names, faces or flat numbers. Reports stay on the map for 7 days, then disappear. Accusations about a person are removed.
Create your building's watch group.
A building watch is a few residents who agree to keep LEON on their phone, report what happens in the common areas and look out for each other, especially the elderly and people living alone.
Tell us about your building. A LEON coordinator will call or write back to agree with you how to start: who the contacts are, how residents join, and what to report.
Starting a watch group is free. Security services, if you ever want them, are quoted separately.
What LEON can provide.
LEON is also a private security company. For a building, a street or a residence, it can add a professional presence on top of the neighbours' watch.

Patrols
Rounds by a uniformed agent at the times that matter for your building, for example late evening and early morning, with a short report after each visit.

A static agent
An agent on site in the lobby, at the car park or at a residence entrance, for a period of tension, building works or an event.


Escort home
A LEON driver or protection agent to bring a resident home at night, booked from the app.
Questions from neighbours.
Does a report on LEON replace calling the police?
No. If someone is in danger, or a break-in is happening now, call 17 or 112 first. LEON warns the people around you; it does not send the police. To press charges, you still need to file a complaint with the police or gendarmerie.
Will my neighbours know it was me who reported?
No. Your name is never shown on the map or in the alerts. For burglaries and sexual violence, the point is moved by about 300 m so that nobody can work out which flat it was.
Can I check an address before signing a lease?
Yes. The map is public, no account needed. Look at the colour of the commune (official figures) and at the dots of the last 7 days, at several moments of the week. The map follows the French Riviera, Marseille and Paris closely, and a growing list of cities in Europe and around the world. Official crime levels exist for French communes only.
Is a red area a place I should not live in?
Not necessarily. The colour compares a whole commune with the French average; streets inside it can be very different. Use it as a first look, then visit the street at night and talk to people who live there.
What does a building watch cost?
Nothing. The app is free and so is setting up a watch group. Patrols, a static agent or escorts are paid services, quoted for your building, and only if you ask for them.
Do we need the agreement of the owners' council?
Not to report or to start a group of neighbours. For anything that touches the common areas, such as posters in the hall or an agent on site, the managing agent and the owners' council have to agree.
What should I avoid reporting?
Names, photos of faces, flat numbers and suspicions about a person. Report what you saw happen, where and when. Reports that accuse or target someone are removed.
