Your Rental Information 
A Key to Fairness.
Alone, you're powerless against unjustified prices. Share your rent information anonymously. This creates a fair basis for you and thousands of other tenants in Switzerland.
Share Rent NowAbsurd Rent Increases as a Problem.
Do you sometimes feel uncertain about your rent? You're not alone.
Without comparison data, it's almost impossible to know if your own rent is fair. This makes it easy for landlords to demand excessive prices.
Collective Knowledge as a Solution.
Imagine we had an anonymous database showing what is actually paid for comparable apartments in your neighborhood. That's exactly what we're building here.
Your rent information is a missing piece of the puzzle.
By sharing your data, you help create a powerful tool for all tenants.
How Your Participation Helps Concretely.
You Create Transparency
Your information creates anonymous rent price comparisons. This allows you and others to see at a glance whether a rent price in the neighborhood is typical or excessive.
You Enable Fairness
When someone wants to challenge a rent, they need comparable properties. Your apartment can – with your explicit consent – become an anonymized reference that helps another person get their rights.
You Benefit Yourself
The next time you move or receive a rent increase, you benefit from the knowledge of everyone who has already participated.
Your Data is Secure. We Promise.
Data protection is our top priority. We have clear rules so you always maintain full control.
Anonymous Statistics
For public average values, your information is anonymized and aggregated. It is impossible to trace back from these statistics to you or your apartment.
Full Control Over Data Sharing
If your apartment is considered as a comparison property for a challenge, we only share information with your permission.
For Tenants Only
Your data will under no circumstances be shared with landlords or property management companies.
A Small Contribution, A Big Impact
Every shared rent makes our system stronger and rental prices in Switzerland potentially fairer. It only takes 3 minutes.
