HealthKit Data
We disclose, in full, what data Feelmo exchanges with Apple's Health app (HealthKit). What it reads, what it writes, and what it does not do — trust, we believe, begins here.
Data Feelmo reads
To measure and watch over your regulation, Feelmo reads the following from HealthKit. Permission is requested step by step, per feature, and you can revoke any data type at any time.
| Data | What for |
|---|---|
| Heart rate variability (HRV / SDNN) | The core metric of the Regulation Score |
| Heart rate | As background, such as resting heart rate |
| Sleep | To read regulation mainly from heart data during sleep |
| Steps & workouts | To watch the relationship between behavior and regulation (behavior log) |
| Ambient light / daylight (where available) | To watch the relationship between sunlight and regulation (behavior log) |
About RMSSD
Feelmo emphasizes RMSSD as a parasympathetic index, computed from the heart-rate-variability data it reads. See Understanding HRV for more.
Data Feelmo writes
As a rule, Feelmo does not write to HealthKit. Your Regulation Score and emotion logs are held within the Feelmo app and are not written back to the Health app.
If we ever do write
Should we add a feature in future to export the Regulation Score to the Health app, it would happen only when you explicitly turn it on. By default, nothing is written.
What Feelmo does not do
- We do not use HealthKit data for advertising or marketing
- We do not provide or sell HealthKit data to any third party, including data brokers (we comply with Apple's guidelines)
- We do not perform medical diagnosis or personal profiling with the data
Checking & changing permissions
You can check or change HealthKit permissions any time from iOS Settings.
Settings → Privacy & Security → Health → Feelmo
There you can toggle read access for each data type, such as heart rate variability and sleep. No permission is needed for features you don't use.
Permissions, step by step
Feelmo does not ask for every permission up front. It asks only for what's needed, at the moment a feature is used (the principle of least privilege).
Where the data lives
The Regulation Score, emotion logs, and behavior logs computed from the data read via HealthKit are kept on your device only, as a rule, and are not sent to our servers automatically. See Data & Privacy and Apple Watch & HealthKit for more.
Not a medical device
Feelmo is not a medical device and is not intended for diagnosis or treatment. For any concerning symptom, please consult a medical professional.
