Health Data Avatar (HDA) is your secure, multilingual hub for managing all your health data across providers, portals, countries and apps. It centralises, organises, and makes your medical records accessible—no matter the source or format. Capture, securely store, structure, summarise, translate, track your symptoms, chat to the whole health picture, export files with your personal information redacted, ready for LLMs (markup). Think of it as health data management as a core product.

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 a patient advocate, needing to review hundreds of pages to help just one person, 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 hospitals, insurers, research. tech, not patients—and the only way to change that is to give users their own tool 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.

We are currently self-financed and will definitely stay independent of big tech and governments, while integrating into healthcare on users' terms, keeping privacy and active consent our core philosophy. While we are hoping to start charging soon and believe in the cross-border future of HDA, we also realise that many startups don't make it. As first and foremost we are patient activists, we really don't want to add to your data nightmare. So we made a pledge: even in a worst-case scenario, your data will stay securely available for five years or until you reclaim it, giving you plenty of time to download or delete everything on your terms.
