Privacy, in plain English
We can't see your data — it's stored in your browser.
What we collect
Nothing. HealthQuant has no server that receives your readings, no account system, and no analytics on the numbers you enter. When you log a metric, it is written to your browser's local storage on this device — the same place your browser keeps things like saved preferences.
What leaves your device
Your data only leaves this device when you choose to: exporting a JSON/CSV backup or saving the report as PDF are downloads you create locally. We never receive a copy.
What this means in practice
- No one — including us — can read, sell, or leak your readings, because no copy exists anywhere but your device.
- Clearing your browser data (or using private/incognito mode) deletes your history. Export a backup regularly — the export button on the report page creates one in two clicks.
- Your data does not sync between devices or browsers. It stays exactly where you entered it.
