Frequently asked questions
Everything people ask us, and a few things they have not asked yet.
Practical questions
How a giveaway works, from the first tap to the handover.
Is Kadoz really free?
Yes, entirely, and both ways: giving costs nothing, receiving costs nothing. There is no subscription, no commission and no paid option.
Asking for anything in return — money, a swap, a contribution towards costs — is forbidden and is a serious breach of our terms. An item listed in order to get something back is taken down and the account deleted. This is not a moral stance: it is what lets you reserve an item without having to haggle.
Where does Kadoz work?
In Belgium and Luxembourg. Both countries are covered in full: 1,145 Belgian postcodes and 4,200 Luxembourg ones, with their towns and municipalities.
Luxembourg assigns its postcodes by stretch of street — 4,200 for 640,000 inhabitants, where Belgium has 1,145 for 11.8 million. A Luxembourg postcode therefore often covers a single street, which makes searching nearby more precise than it is in Belgium.
On the website you can browse and reserve in both countries: choose the country before entering your postcode. Listing an item requires the app, which asks for your country when you sign up.
How do I list an item?
A photo, a title, a category, a postcode. The app reads the photo and often suggests the title and category on its own: all you have to do is confirm or correct them.
The volume is worked out from the category — a chest of drawers is 1.20 m³, a chair 0.20. That figure feeds the cubic metres kept off the pavement in your municipality.
Is my address visible?
No. Until you have accepted a request, your item appears only with its town and an approximate circle — never a pin on your front door.
Your exact address is passed only to the person whose request you have accepted, and only to them. If you withdraw your item or cancel, they lose access to it.
How long does my reservation stay valid?
Forty-eight hours from the moment the item is available. After that, if the exchange has not moved forward, the item goes back online and the people who were waiting for it are notified.
An exchange that “moves forward” means a real message in the conversation. As long as you are talking, nothing expires: the time limit exists only to free up items that nobody is responding about any more.
How does the handover work?
The person collecting the item shows a four-character code. The giver scans it or types it in. That action, and that action alone, closes the giveaway.
Without that code, the item stays marked as reserved: it no longer appears in searches but is not counted as given. Get into the habit of scanning it there and then, not later — later, people forget.
How many items can I reserve at once?
Two active collection points at most, and up to six items per collection point. In other words: you can take six items from the same person, but not one item each from six different people.
This limit exists because a reserved item is an item nobody else can see. Reserving widely “just in case” ties up items that someone genuinely needs.
What if nobody comes to collect the item?
Once the time limit has passed, you can report that the person did not turn up. The item goes straight back online and the no-show counts against that person’s reliability. At the third, they can no longer reserve for fifteen days.
Reporting is possible only after twelve hours, so that a giver in a hurry does not penalise someone who is on their way.
The giver is not answering or was not there. What should I do?
You can report it once the agreed slot has passed. You are not penalised in any way, and the no-show counts against the giver: at the third, they can no longer list items for fourteen days.
If the giver simply never answered your request, there was no appointment and therefore no no-show. The item goes back online on its own, and nobody is marked.
I am moving house and have twenty items to give away. How should I go about it?
List them as usual, but group them into a batch. Someone who reserves from a batch can take up to six items in a single trip, with a single handover code.
It is the right way to clear out a cellar or an attic: a visitor who leaves with six items saves you six appointments, and is often keener than a visitor who only wants one.
Technical questions
The app, notifications, your account.
Do I need the app, or is the website enough?
The website lets you browse items, ask a question and reserve. That is enough to receive.
To give, the app is far more practical: it takes the photo, reads the item, works out the volume and lets you scan the handover code on the spot. It is free on iPhone and Android.
I am not receiving notifications
First check that you have allowed them for Kadoz in your phone’s settings: that is the cause in the vast majority of cases, and the app cannot do anything about it itself.
If you would rather not turn them on, you will now receive important messages by email — a request for one of your items, a message in a conversation, an appointment coming up. The email arrives a few minutes later, never within the second: that is the limit of this channel.
Why does Kadoz ask for my postcode?
To show you what is being given away around you, and to link your giveaways to your municipality. Without it, the list of items opens on nothing the first time you launch the app.
The postcode stays at the level of the town. It only becomes a precise address for an item you list, and only for the person whose request you accept.
How do I change the language?
Kadoz is available in French, Dutch and English. On the website, the selector at the top of the page switches language while staying on the same page.
In the app, you choose in your profile. Notifications and emails follow that setting.
How do I close my account?
From your profile, in the app. Closure is immediate: your items still online are taken down, your conversations deleted, and your personal information — username, photo, phone number, address — erased.
It cannot be undone and you do not have to give a reason. If you come back later, you will need to create a new account.
The app crashes or freezes
Close it completely — by swiping it up — then open it again twice: the first time downloads the update, the second puts it into service. Most fixes arrive this way, without going through the app stores.
If the problem persists, uninstall and reinstall: your items, your conversations and your history are on our servers, nothing is lost. And write to us at hello@kadoz.app telling us which phone and at what point it happens — that is what allows us to fix it.
Which phones does Kadoz work on?
iPhone from iOS 15, and Android from version 8. Maps, the camera and code scanning work on both.
What do you do with my data?
We keep what is needed for the service to work: your username, your email address, your town, and your items. Nothing is sold, nothing is passed to an advertiser.
Your exact address is visible only to the person whose request you accept. Conversations closed for more than three months are deleted automatically. The details are in our privacy policy.
Tips
What makes an item go, and what makes it stay.
Is anyone interested in a broken or faulty item?
Yes, and it is probably what Kadoz does best. You can say that an item is not working, needs repair, or is good for parts — and that is not a flaw to hide, it is information someone is looking for.
A washing machine that no longer drains interests the neighbour who knows how to change a pump. A bike with no back wheel interests the one with a spare wheel. A dead toaster interests a repair café. These items go, often faster than intact ones, because whoever takes them knows exactly what they are coming for.
Be precise about the fault. “No longer heats up” is useful; “needs repair” on its own says nothing and puts people off.
What photo should I take?
One good photo is better than five bad ones. The whole item, in daylight, against a clear background — push everything else out of the frame rather than looking for a setting.
If the item has a flaw, photograph that too. A scratch that is shown is a scratch that is accepted; a scratch discovered on the doorstep is a wasted trip.
How do I describe an item so that it goes quickly?
Say what the photo does not show: the dimensions, the brand, whether it works, what is missing. A clear title and three precise lines are worth more than an enthusiastic paragraph.
And say if it is heavy or bulky. Someone who finds out on the doorstep that it takes two people and a van leaves empty-handed, and you start again.
What cannot be given away on Kadoz?
Anything that is illegal to hand over, anything dangerous — weapons, flammable products, medicines —, animals, and anything that concerns the person rather than the item.
Child car seats and helmets are best avoided: their safety depends on a history of impacts that nobody can check. And nothing is given in exchange for anything, in any form whatsoever.
How can I be notified when an item I am waiting for becomes available?
If an item is already reserved, you can register your interest. If it goes back online — and that happens often —, you are notified immediately, with your place in the queue.
You can also create an alert for what you are looking for. Kadoz will let you know when a matching item is listed near you, without you having to come back and check every day.
My item is not going. Why?
Three causes, in order of frequency. The photo does not show the item clearly. The title is vague — “assorted bits” tells nobody what they are coming for. Or the category is wrong, and the item does not appear where people look for it.
Edit the listing rather than listing it again: a new photo and a precise title are enough most of the time. And give it a few days — the person looking for exactly your item may not have been online today.
