Frequently asked questions

How do I export my Apple Health data to CSV?

Install Vitadatum, grant it read access to Apple Health, and choose a CSV export. You get a summary CSV with 26 daily columns plus detailed per-metric files covering your full history — all generated on your iPhone.

Can I export Apple Health data for ChatGPT or Claude?

Yes. Vitadatum exports structured JSON, the format AI tools read most reliably, so you can upload it straight to ChatGPT, Claude, or any LLM. Vitadatum doesn't do any AI itself — it just prepares your data in the format those tools prefer.

Does Vitadatum upload my health data anywhere?

No. Everything happens on your device. No accounts, no cloud uploads, no analytics, no tracking. Your health data never leaves your iPhone unless you share the exported file yourself.
