Privacy Policy

Effective September 27, 2026

The short version: Calenta processes your health data on your own devices. By default, Calenta collects and transmits nothing. There is one optional, off-by-default program — contributing pseudonymized data to improve meal detection — which runs only if you explicitly turn it on through an in-app consent screen, described below.

What Calenta reads, and why

With your permission, Calenta reads the following from Apple's HealthKit and Motion & Fitness frameworks on your iPhone and Apple Watch:

Heart rate — to detect the physiological response to eating
Steps and workouts — to avoid mistaking activity for meals
Wrist motion and activity classification — to recognize eating gestures and rule out walking
Weight and energy data (if present) — for calorie budgets and trends

All of this is processed on your devices. Meal detections, calorie history, and everything you log are stored locally on your iPhone.

What we collect by default: nothing

Unless you opt in to the contribution program below, Calenta sends no health data, no analytics, and no identifiers to us or to anyone else. There are no ads, no trackers, and no third-party SDKs. We never sell data.

Optional: the data contribution program

In Profile → Data Contribution, you can choose to help improve Calenta's meal detection. This is optional and off by default. If you turn it on, you will first see a consent screen describing exactly what is shared; only after you agree does anything upload.

What is shared: heart-rate samples, step counts, workout sessions, wrist-motion scores, activity segments, detected meal events, and the labels you provide (taps, dismissals, logged meals).
How it is identified: only by a random install identifier generated on your device — never your name, email, phone number, or Apple ID.
Where it goes: encrypted in transit to Calenta's own server (not iCloud, not any third party). It is used solely to train and evaluate Calenta's meal-detection and calorie models — never for advertising, never sold.
Retention and deletion: kept while the improvement program runs. Turn the toggle off anytime to stop future uploads; to delete already-contributed data, email us the install ID shown in the app (Profile → Advanced tools) and we will remove it.

Data deletion

Your app data lives on your devices: deleting the Calenta app deletes it. You can also revoke Calenta's Health access at any time in the iPhone Settings app → Privacy & Security → Health. Contributed training data (if you opted in) is deletable on request as described above.

Health disclaimer

Calenta provides estimates for general wellness purposes. It is not a medical device and does not provide medical advice, diagnosis, or treatment.

Changes

If this policy changes, the updated version will be posted at this address with a new effective date.
