Health data and safety
Draft. Counsel has not reviewed this text yet.
Fitness guidance, not medical advice
GymPower provides fitness guidance, not medical advice. Consult a doctor before starting a new program, especially if you have a condition or injury.
- You see this at onboarding, and you confirm it.
- If something hurts, stop. GymPower can swap the exercise and suggest a professional. It never gives a diagnosis.
- GymPower is for natural lifters. It has no content about performance-enhancing drugs.
- In an emergency, call your local emergency number.
What health data we use
If you allow it, the app reads these values from Apple Health, Health Connect, a Fitbit tracker (through the Google Health API) or WHOOP (through the WHOOP API):
- steps;
- heart rate and heart rate variability (HRV);
- sleep.
We use them only to make your readiness score, show your weekly habits and, if you choose, your steps in a challenge.
What stays on your phone
Raw heart rate, HRV and sleep from Apple Health and Health Connect never leave your phone. Our servers keep:
- your daily steps, and
- one readiness score per day.
If you connect a Fitbit tracker, Google sends its heart rate, HRV and sleep to our server, not to your phone. We only pass them on. They wait on our server, encrypted, until your phone collects them. Then we delete them. Values your phone does not collect are deleted after 7 days.
WHOOP works the same way. If you connect WHOOP, we read only last night's sleep, your recovery HRV and your resting heart rate. We do not read WHOOP's recovery score, strain, workouts or profile. When you disconnect WHOOP, we cancel our access at WHOOP and delete its values on our server and on your phone. We never use WHOOP data to build or train AI.
Your health check answers
The health check asks about heart conditions, chest pain, pregnancy (women only), medicine and injuries. It makes your plan gentler and may suggest you see a doctor. It never blocks you. These answers are health data. We use them only for your plan and for your safety notices.
Two separate choices
You choose each one on its own, and you can change them any time in Settings.
- Collect my health data. We read the values above to make your readiness score.
- Share my health data. Members of a challenge you join can see your steps for that challenge.
Saying no never blocks training. If you say no, readiness uses your daily check-in only.
How to withdraw
Go to Profile, Settings, and turn the switch off. When you turn off collection, we delete the health data we hold on our servers. You can also delete your whole account there.
Our promises
- We never sell health data and never use it for advertising.
- Health data is kept in a separate, restricted part of our database, and is never sent to analytics.
- We follow Apple's HealthKit rules and Google's Health Connect rules.
