VO2max Hero reads VO2max, date of birth, biological sex, height, and weight from Apple Health so we can show your stats and personalize AI insights. We never write health data. Health samples stay on your device except the values you choose to send when requesting an AI insight.
Purchases are processed by Apple. We use RevenueCat to check whether your Pro subscription is active so we can hide ads and unlock extra AI insights. RevenueCat receives an anonymous app user ID and purchase status, not your Health data.
Free users see a banner ad served by Google AdMob. Pro subscribers do not see ads.
App Store builds send anonymous usage events (for example tab taps and paywall funnel events) through Firebase Analytics. Debug and TestFlight builds do not enable analytics collection.
If you request an AI insight, the selected VO2max readings and any available demographics are sent to our proxy so a language model can generate the response. Free includes 1 insight per hour. Pro unlocks extra insights with a fair-use cap. We do not sell personal data.
