• Every 30 days you need to log in again. M4you will notify you.

• Sometimes M4you has just been updated and it may take a bit longer before you can log in.

To create an account in M4you, we need your name, email address, date of birth and patient number.
We use this information to make sure that only children we know can join M4you. It also allows you to chat safely with other children using the app.
In your M4you profile, you can choose what information other users can and cannot see.

We use your patient number once to check if you are being treated at the Princess Máxima Center. This ensures that M4you is only available to children receiving care at the Máxima Center.

Not yet. In a future version of the app, there will be a separate group for siblings.

A staff member from the Princess Máxima Center has access to your information to place you in the right community within M4you. Healthcare professionals do not have access to the communities. In the app, you can decide which details other M4you users can see. You can change this anytime in your profile.

All data is securely stored and can only be viewed by designated administrators — and only when necessary.
Chats are visible only to you and the person you’re chatting with, unless you give an administrator permission to view them.

When you sign up, we need your name, date of birth, email and patient number.
If you don’t share this information, you unfortunately can’t create an M4you account.
After signing up, you can decide in your profile which details are visible to others.

Only the person you’re chatting with can see your messages.
If a chat becomes unpleasant, you can click Report. An administrator will then review the chat. In the chat, you’ll see when an administrator has access and when they no longer do.

If you delete your account, your information will be stored for 14 more days in a backup. After that, it will be permanently deleted.

No, not normally. Only the bulletin board messages are monitored to prevent unwanted posts.
Private chat messages can only be viewed by an administrator if you click Report.
In that case, the administrator can see only the messages in that specific chat — not your other conversations.
Once the administrator has helped you, they leave the chat again.

When you’re in the 3D world, you can change your avatar at any time. You can also give your avatar a name by clicking the name button below it.

You can’t change your name or date of birth, but you can update the other fields in your profile. You can also choose which information other M4you users can see about you.

In the 3D world, you can also create avatars of the healthcare professionals in your care team.

You can use the bulletin board for this. All children in your M4you group can see the board and post messages there.

From the age of 8, every child gets access to the chat. There is no chat option for children younger than 8.

Click Report in the chat. An administrator will then join your chat, take a look with you and help you.
Once the issue is resolved, the administrator will leave the chat again. You’ll see a message showing that the administrator has signed out.

Unfortunately, that’s not possible.

Every day, healthcare professionals check which children have signed up for in-room activities. They make a list of who can take part.
It’s possible that no one comes to your room, for example, if the activity is full or if you have an examination or treatment at that time.
If you have questions about this, ask your nurse or child life specialist.

That’s not always possible unfortunately. We try to offer some activities online. If that’s the case, it will be mentioned in the activity description.
