NotFit reads health and fitness data only after you connect a source: Health Connect on Android, Apple Health on iOS, or a WHOOP, Garmin or Oura account. What we read:
- Health Connect on Android: your step count, active calories burned, and the start and end times of your exercise sessions. NotFit does not read sleep or heart rate from Health Connect.
- Apple Health on iOS: your step count, active energy burned, Apple exercise minutes, workout session times, sleep sessions and time in bed, and heart rate samples.
- Connected wearable accounts: if you link WHOOP, Garmin or Oura, we collect sleep duration, resting heart rate, heart rate variability, that provider’s recovery score, and daily steps where the provider reports them, from their servers.
- Values you enter yourself: you can type in steps, exercise minutes, active calories, sleep minutes, resting heart rate and heart rate variability for any date.
- Reading in the background: once you connect, NotFit reads these values while the app is closed. On Android that is roughly once an hour. On iOS it is a background refresh task plus the home screen widget, which reads your step count on its own, so your rings and your widget stay current.
- What reaches our servers: daily totals only, stored against your account with the date and the name of the source: steps, sleep minutes, active calories, exercise minutes, a daily heart rate figure, heart rate variability and a recovery score. Individual heart rate readings and individual workout records stay on your device.
- What we use it for: filling the activity rings and the day card on your home screen, the history and trends views, the leaderboards and the compare card, and, where health reminders are enabled, choosing which reminder to send you. Reminder text never contains your numbers.
- Coach AI and Taz: when Coach AI or Taz writes to you, whether in the app, on WhatsApp, or in your daily affirmation, a short summary of your recent steps, sleep, heart rate, heart rate variability and recovery score is sent to our AI model provider, OpenAI, so the message can take it into account. Messages sent over WhatsApp travel through Twilio and WhatsApp.
- Other members can see some of it: the steps, sleep and recovery leaderboards and the compare card show your figure next to your name and profile picture to other NotFit members. To keep your figures off those boards, disconnect your health source.
- How we protect it: health data travels over HTTPS, is stored in an encrypted database hosted on Amazon Web Services, and is reachable only by NotFit staff who need it to run the service and by the AI model provider named above.
- What we never do with it: we do not sell your health data, do not share it with advertising networks or data brokers, do not use it for advertising or profiling, and do not use it to decide credit, lending, insurance or employment. It is not sent to our analytics or advertising tools.
- How long we keep it: we do not delete health data on a schedule. Each daily entry stays on our servers until you ask us to remove it, until you delete your account, or until it is cleared because you connected or switched a source.
- Turning it off: open the wearables screen in your NotFit profile and tap Disconnect. That cancels the widget upload straight away and stops NotFit syncing from your phone. To stop all reading immediately, also withdraw the permission in Health Connect on Android or Apple Health on iOS. Neither of those deletes data we already hold.
- Deleting it: email support@notfit.io and we will delete the health data held against your account. Deleting your NotFit account deletes it as well. Connecting or switching a source clears the data we already synced from any earlier source, apart from values you typed in yourself.
NotFit only reads from Health Connect and Apple Health. We never write anything back to them. Health data is used for general fitness and wellbeing only. It is not used to diagnose, treat, cure or prevent any condition, and NotFit is not a medical device. For questions or a deletion request, email support@notfit.io.
