Data Ethics & Clinical Responsibility Statement
At Yellow Riders, we build digital therapeutic tools and cognitive support systems with the understanding that these products can affect people in vulnerable situations.
We therefore commit to the following principles.
1. Human wellbeing comes first
Our first responsibility is to support the wellbeing, dignity, and autonomy of the people using our products.
We aim to design tools that are supportive, understandable, and appropriate for people with cognitive challenges, including people recovering from brain injury.
2. Technology supports care, not replaces it
Karman Line and OtonoMe are designed to support rehabilitation, self-management, and daily functioning.
They do not replace qualified clinical judgement, diagnosis, or emergency care.
Where a product is used within a rehabilitation pathway, we expect clinical supervision and professional responsibility to remain clear.
​
3. Data minimization and proportionality
We aim to collect the minimum amount of data needed to make the service work.
We do not collect personal data simply because it may be useful later. We collect data only where there is a clear functional, scientific, or legal reason to do so.
4. Transparency and understandable communication
We aim to explain clearly:
-
what data is collected
-
why it is collected
-
how it is used
-
when it is stored, anonymized, or deleted
We also aim to communicate honestly about what our products can and cannot do.
5. Privacy and security by design
We design our systems with privacy, pseudonymization, and security in mind from the start.
Where possible, identifying information is separated from behavioral or activity data. Access to data is restricted and protected through technical and organizational safeguards.
6. Scientific integrity
Where our products are used for research, validation, or clinical evaluation, we aim to follow accepted scientific and ethical standards.
We value reproducibility, methodological care, and honest reporting of results.
7. Responsible innovation
We recognize that digital health tools can create both opportunity and risk.
As a result, we treat product development as an ongoing responsibility. We continuously evaluate usability, safety, interpretability, and expected benefit, and we improve our systems when shortcomings are identified.
8. Respect for user control
Users should be able to understand their relationship with the product and exercise control over their own data where applicable.
This includes the ability to request deletion of account-related data and to receive clear information about how the service works.
9. Collaboration with care and research partners
We work with clinicians, rehabilitation specialists, and academic institutions to improve both product quality and scientific grounding.
We believe responsible digital therapeutics should be built in dialogue with practice, not in isolation from it.
10. Continuous improvement
We see privacy, ethics, and clinical responsibility as continuous processes rather than one-time statements.
We will keep refining our products, policies, and safeguards as technology evolves, clinical knowledge improves, and user needs become clearer.
