Responsible AI
GDPR compliant +
governed by responsible values
GDPR compliance is only the start. Privacy is at the core of our solutions with stringent policies and oversight that not only meet but exceed the requirements of the GDPR. We view compliance not as an endpoint but as a foundation upon which we build. Our work is directed by a set of deeply held responsible values, extending our commitment to privacy, security, and ethical considerations beyond the regulatory baseline.
We are always in close contact with the users of our products by means of structured surveys or interviews to assess their wishes. We also contribute to societal relevant projects, which helps participants become aware of the kind of data technology can gather from them.
Human-centric
We design technology that works for people, not against them
People with a darker skin color are underrepresented in many datasets, which often leads to lower classification performance. We try to mitigate this by balancing the composition of our training data and continuously testing our software against benchmark datasets (e.g. Gender Shades). This way we strive to have the same high level of accuracy for different groups of people.
Fair
Our algorithms are fair with minimal bias
We incorporate a Privacy by Design approach in our products and we always respect participants' privacy in the datasets we use. For example, in FaceReader Online, our clients sign a processing agreement and participants are required to give informed consent before participating. Additionally, we have the option not to store video recordings, but only anonymous metadata.
Privacy friendly
Privacy protection is embedded in the design of our technology
Our algorithms are not a black box and we have tools and documentation in place to explain our results to our users. As an R&D company, we frequently publish about our new technology, providing transparency into the functioning of our algorithms.
Transparent
Our algorithms and motives are overtly explainable
We have security protocols in place to make sure our stakeholders' data is safe with us. For example, all communications with our database servers happen through an encrypted connection.
Secure
We safeguard all data entrusted with us
Our technology does well in quality assessment tests (e.g. Stockli et al, 2017). We spend a lot of effort in updating our algorithms and label new developments that are not completely validated yet as experimental.
Competent
We design technology according to up-to-date standards

Working with FaceReader Online completely changed my perspective. I can now handle more clients in a shorter amount of time and it changed my life and business!
Patryk WawrzyńskiCEO at Alpaka Innovations 
The outstanding advantages of FaceReader Online are the fast availability of results, technical implementation support, affordable price and great communication. More important today, Ipsos needs to be a game changer, not just a data supplier to its clients.
Michal StepanekExecutive Director at Ipsos 
When I started the FaceReader Online trial, I saw the dashboards and it was exactly what I was looking for. I was getting all the metrics I needed in my research.
Monica GonzalezResearcher at Anáhuac University 
Before FaceReader, we tried other software, but the quality was not even close and it was impossible to download the emotion data at the participant level. When we found FaceReader, it was too good to be true.
Lucía FreiraResearcher at Universidad Torcuato Di Tella 
I compared four commercial facial coding tools, and FaceReader Online clearly stood out from the beginning. The intuitive way to build experiments was a key factor for us.
