Senior Health Privacy and Data Considerations
How senior health data should be handled: local-first processing, encryption and real user control.

For older adults, hydration, regularity and early signals are central to independence and wellbeing.
Sensitive by nature
Data about senior health is deeply personal, so it deserves the strongest protections by default.
How it should work
The most sensitive signals from hydration and concentration cues should be processed on-device, minimised, encrypted and deletable on demand.
- Hydration and concentration cues
- Digestive regularity
- Meaningful deviations for caregivers
“The test you take every day beats the perfect test you take once a year.”
Trust is the product
A monitor you don't trust won't be used — so privacy isn't a constraint on tracking senior health, it's the point.
