Use:
4WALLS does not store any restricted scope data. 4WALLS collects the origin of the login provider (namely Google Inc.) and a salted hash of the user email or the login supplied by Google Inc. Thus we ensure user anonymity.
The transformation of the login into a hash is done using the state-of-the-art sha256 library for cryptographic hashing. The user’s email or login itself is not stored. A reversal from the hash back to the email or login is not possible, neither is a probabilistic user re-identification, since only common expressions of taste and real estate values are stored. The user login is therefore completely anonymised. More details in our privacy declaration.
Transfer:
4WALLS does not store any restricted scope data. 4WALLS data is completely anonymised.
4WALLS also does not transfer any collected data to other parties either.
Only aggregates of the data will be used and only for scientific publications.
(a) There are no user-facing features, that would require this.
(b) No legal obligations subject us, to share data with governments or authorities.
In the event that a government or authority rightfully claims our data,
there will be only anonymous data available.

Advertising:
4WALLS does not store any restricted scope data. 4WALLS data is completely anonymised anyway.
4WALLS is an academic research project. 4WALLS will not sell any of its collected data to advertisers either. 4WALLS would risk being defunded and risk losing its academic reputation and subsequently its livelihood.
Human Interaction:
4WALLS does not store any restricted scope data.
4WALLS makes its collected data available only to the research team. 4WALLS data is completely anonymised anyway. Project leader and prime contact is Dr. Thies Lindenthal of the University of Cambridge, htl24 at cam.ac.uk. The project team currently consists of two academic researchers and one technician.
