Health Data Avatar

General Questions

What is Health Data Avatar?

HDA is a secure, multilingual platform that allows users to centralise, organise, and manage their health data from multiple sources and formats.

Why did you create this project?

HDA was born out of personal frustration with how fragmented and scattered health data is. Even in perfect circumstances with full interoperability that is hardly achievable in the immediate future, crucial, day-to-day details that impact real decision-making won't make it into clinical notes—leaving gaps in care and making true prevention nearly impossible.

Both co-founders have faced these challenges firsthand—one as a clinician and neurodivergent patient navigating healthcare in 4 languages across multiple countries, and the other as a chronic illness patient struggling with the bureaucratic nightmare of accessing health and disability support.

We realised that existing solutions are built for health institutions, not patients—and the only way to change that is to empower individuals to take control of their own data. With HDA, we are creating the tool we wish had existed for ourselves and countless others in the same situation.

Security and Privacy

Why should I trust you with my health data?

Health data is highly sensitive, and data security is the foundation of our platform. That's why HDA follows the highest standards in data security, encryption, and privacy compliance.

We're UK based, meaning we're subject to the General Data Protection Regulation (GDPR), ensuring that your medical data is protected and handled responsibly.

We do not sell or share your data with third parties. Our goal is to empower you, not exploit your information.

Who owns the data I upload to HDA?

You do. HDA does not claim ownership of your data. You have full control over what you store, edit, or delete at any time. We don't use it for any purpose other than providing you with the service you signed up for.

How is my data protected?

Your data is encrypted while being transferred between the user and HDA, and while being stored on our servers. We use the latest encryption standards to ensure your data is safe.

We implement strict access controls to ensure that only you, the user, can choose who accesses your data.

What data is stored?

Unlike traditional systems controlled by hospitals or insurers, you decide what medical data to store, update, or delete.

If you send us any feedback through the app - firstly, thank you! - we remove any personal identifiers from your feedback before storing it. This helps us improve the app while keeping your feedback anonymous and your data private.

Our privacy policy covers everything in more detail.

Features and Functionality

What are HDA's key features?

AI-Powered Chat: Instantly find answers from years of accumulated medical data.
Multilingual Integration: Upload and manage records in any language or format.
Smart Search: Quickly locate specific health documents.
Data Reclamation: Retrieve health records directly from providers.
Document Automation: Generate letters, forms, and insights seamlessly.
Secure Sharing: Share data with providers without compromising privacy.

Are you planning to integrate with the NHS app?

The NHS uses a variety of Electronic Health Record (EHR) systems across its trusts, many of which cannot communicate effectively with each other. This lack of interoperability creates data silos, with patient records often scattered across multiple systems—some available digitally, others only in printed or handwritten formats.

While we aim to integrate with as many health data providers as possible, including the NHS app, integration alone often results in incomplete and inconsistent data. Therefore, our focus is on empowering users to reclaim and consolidate their health data directly, regardless of its format or location.

Can HDA integrate with my wearable devices?

In the future, HDA will support integration with devices like Fitbit, Garmin, or Apple Health, providing real-time health data insights.

Can I manage multiple profiles on HDA?

Absolutely. HDA will allow you to create and manage profiles for family members and share access, making it a versatile solution for households.

‍

Pricing and Plans

Is HDA free?

Currently, HDA is free to use, and we do not charge for the core functionalities. In the future, we will introduce extra paid features, but our priority is to keep the core data management tools accessible.

What is included in the free plan?

The free plan provides:

Secure data storage.
Smart search to locate your health records.
Basic health profile management.

Will I lose all my data if I stop paying for the subscription?

💡 You’ll never lose your data.

No. All the data you’ve uploaded will remain in your profile, even if it exceeds the free 500MB limit. You won’t lose access to your records, but you won’t be able to upload new files until you subscribe again. You’ll still be able to use features like cross-lingual search, health journal, update your profile, and share your data.

What happens to my data if I stop paying for the subscription?

💡 Your data stays safe and accessible.

You can continue using HDA for free with up to 500MB of storage (that’s a lot of files, so most users won’t hit the limit quickly).

If your account already exceeds 500MB, you’ll keep access to all your files, but you won’t be able to upload new ones.
If you still have space left under 500MB, you can upload new files, but these won’t be summarised (or have their data structured) without a subscription.
You’ll still have access to your existing data, cross-lingual search, and your health journal, but not the AI chatbot.
You can still share access to your data.

Technical and Support

Can I upload documents in any format?

HDA supports multiple formats, including PDFs, images, text files, and even handwritten notes.

What if I encounter technical issues?

HDA provides customer support via email to assist with any issues.

Will HDA provide medical advice?

No, HDA does not offer medical advice. It provides insights and tools to help users manage their data but leaves clinical decisions to healthcare professionals.
