FAQ
What to know before you buy.
Key questions about privacy, exports, and practical use.
Are my health data uploaded to a cloud?
No. Strata is designed for local processing. Export files are only created when you explicitly trigger them.
Can I choose the export format freely?
Yes. For each export, you can choose CSV, JSON, or Markdown.
Why is the app called Strata?
“Strata” means layers. That is exactly how the app treats your health data: from activity and vitals to mental health as clearly separated, exportable layers.
Can I evaluate exported data with a local LLM?
Yes. That is a core use case. You can process export files with local AI tools without giving up ownership. Your data stay your data treasure.
Is Strata suitable for non-technical users?
Yes. The app guides users step by step through permissions, profile visibility, and export.
Does Strata provide medical advice?
No. Strata provides access and structure for your own data, but it does not provide diagnosis.
