Question 1

After taking part, can I see what other participants pay for their apartment?

Accepted Answer

Not during an ongoing proceeding. You see your own comparison against anonymised neighbourhood data (if available), but never the individual details of other participants. This protects everyone involved from being identified. An anonymised insight into the other apartments of a case is only possible after the conciliation – and only from those who have likewise consented.

Question 2

Will my landlord find out that I shared my data?

Accepted Answer

No. One of the biggest obstacles is the justified fear of consequences from the landlord. Your data is safe with us. We never proactively pass on information to landlords or property management agencies. Relevant information about your apartment will only be used for the evidence dossier of the contesting person (tenant) with your consent.

Question 3

Will I have to testify later for my neighbors before the conciliation board or even in court?

Accepted Answer

Absolutely not. Your support takes place completely in the background on our platform. You simply share your apartment details for the evidence dossier that the tenants need for the dispute. You will not be invited to an official hearing, and you accordingly do not have to appear or testify there.

Question 4

How much time does it take to participate?

Accepted Answer

Entering your apartment details usually only takes about 2 to 3 minutes. This brief investment is enough to sustainably strengthen the foundation for fair rents in your neighborhood or municipality.

Question 5

Exactly what documents or information do I need to have ready?

Accepted Answer

To make your apartment details useful, ideally you need your current lease agreement and (if available) the latest notice of rent change. We ask for key data such as the current net rent, utility installments, number of rooms, square meters, and the year the apartment was built or renovated.

Question 6

What happens if my apartment is not suitable for the current dispute?

Accepted Answer

Your data is still extremely valuable for the neighborhood! If your apartment doesn't quite fit the current call, you can flexibly decide what happens next via your sharing settings. You have two options: Either you generally release your data so that it can automatically support future disputes in your neighborhood. Or you use our "On-Demand" function: We will inform you by email as soon as your apartment could match a new, future case. You can then decide individually for each dispute whether you want to share your data.

Question 7

I don't live where the apartments of the currently ongoing disputes are located. Why should I participate anyway?

Accepted Answer

Because the real estate market is a give and take. If landlords do not disclose their returns, tenants are dependent on swarm intelligence. By sharing your data today, you benefit from two things: The reality check – You find out through our platform whether your own rent might belong to the most expensive 10% in the neighborhood. Solidarity – Tomorrow your neighbor might move out and the new tenant will be confronted with a massive rent increase. Your anonymously stored data is the protective shield for your neighborhood.

Question 8

What do I get out of taking part in a case?

Accepted Answer

When you share your apartment details, you find out whether your apartment fits this case. If it does, you receive – once the dispute has been through the conciliation authority and only with your explicit consent – an anonymised report on the case and the other apartments.
