When you share information about your mental health with a therapist, or with a digital platform like HealthNest, you are placing an extraordinary degree of trust in the people and systems on the other side of that conversation. Mental health data sits at the top of the hierarchy of sensitive personal information. It can affect employment, insurance, relationships, and personal safety. The obligation to protect it is not merely legal. It is deeply ethical.
At HealthNest, privacy is not a feature we added after building our platform. It is a design principle that has shaped every architectural and operational decision from the beginning. This article explains what we do to protect your data, why we do it, and what that means for your experience as a user.
What Data We Collect and Why
We collect only the data we need to provide you with a high-quality, personalised service. This includes the information you provide during registration and onboarding: your name, contact details, and the information you share about your current mental health situation and therapeutic goals. It includes data generated through your use of the platform: mood logs, session notes accessible to your matched therapist, engagement with self-help content, and responses to wellbeing check-ins.
We do not sell your data. We do not share it with insurers, employers, or advertising networks. We do not use your data to train general-purpose AI systems without explicit, informed consent. Every piece of data you generate on the HealthNest platform serves one purpose: helping us provide you with better, more personalised support.
Encryption: Your Data in Transit and at Rest
All data transmitted between your device and HealthNest's servers is encrypted using TLS 1.3, the current gold standard for transport layer security. This means that even if your network connection were intercepted, the data being transmitted would be unreadable to any third party. This applies to every interaction on the platform: session video calls, message exchanges with your therapist, and data entered into mood tracking tools.
Data stored on HealthNest servers is encrypted at rest using AES-256 encryption. This standard is used by defence and intelligence organisations worldwide and is widely regarded as computationally infeasible to break with current technology. Encryption keys are managed through a dedicated key management system with strict access controls and regular rotation.
Therapy session recordings, where applicable and with your explicit consent, are stored in isolated, access-controlled environments separate from general platform infrastructure. Access to these recordings is restricted to the relevant therapist and the client, and they are automatically deleted in accordance with our data retention schedule unless you choose to retain them.
GDPR Compliance and Your Rights
HealthNest operates under the UK General Data Protection Regulation and the Data Protection Act 2018. These frameworks provide you with a comprehensive set of rights regarding your personal data, and we are committed to supporting the exercise of those rights fully and promptly.
You have the right to access all personal data we hold about you at any time. You have the right to correct any inaccurate data. You have the right to request deletion of your data, subject to any legal obligations we have to retain certain records. You have the right to object to specific types of processing, and the right to data portability, enabling you to take your data to another service. These rights can be exercised by contacting our Data Protection Officer at any time through your account settings.
Our lawful basis for processing your health data is explicit consent, freely given and specific. We do not process sensitive health data under any basis that does not include your active agreement. You can withdraw consent at any time, and we will cease processing your data accordingly.
Who Can Access Your Data
Your matched therapist has access to the clinical data you share through the platform: your session notes, mood logs, and any information you have indicated you wish them to see. They operate under the same professional ethical obligations regarding confidentiality as any registered therapist. Their access is governed by a data processing agreement that specifies the permitted purposes and the security standards they must maintain.
HealthNest's internal team accesses anonymised, aggregated data to monitor platform performance, improve features, and ensure clinical safety. A small team of clinical safety staff may access identifiable data in exceptional circumstances, specifically when there is a serious and credible concern about immediate risk to a user's safety. This is consistent with the legal and ethical duty of care that applies to all registered mental health services and is explained in full in our Privacy Policy.
Third-Party Services and Data Sharing
We use a limited number of third-party services to operate the HealthNest platform, including cloud infrastructure providers and video conferencing technology. Every third-party provider undergoes a rigorous data protection assessment before engagement, is bound by a data processing agreement, and processes data only in accordance with our instructions. We do not allow third parties to use HealthNest user data for their own purposes.
We do not share your data with third-party advertisers, data brokers, or marketing platforms. Our business model is built on subscription fees, not on the commercial exploitation of user data.
Our Commitment Going Forward
The regulatory and threat landscape around data privacy changes continuously. We maintain a dedicated information security programme with annual independent audits, ongoing staff training, and regular penetration testing of our infrastructure. We are transparent with users about any changes to our data practices, with clear communication before changes take effect and explicit re-consent where required.
If you have questions about how your data is handled, our Privacy Policy provides full details and our Data Protection Officer is available to respond to specific queries. Your trust is the foundation of everything we do at HealthNest, and we treat the responsibility to protect your privacy with the seriousness it deserves.
