Apple Watch, WHOOP, Oura, Garmin, and Apple Health. MinervaOS reads activity signals (steps, heart rate, HRV, VO₂max, workouts, sleep) to sharpen your burn estimate.

No — you can use MinervaOS with just your phone. But connecting a wearable makes your calorie-burn number meaningfully more accurate.

A food photo is sent to our AI provider to generate the estimate, and a copy is kept on your device so you can review the entry. We don't store your food-scan photos on our servers. See our Privacy Policy.

No, and no. No ads, no data brokers, no cross-app tracking. Your Apple Health and wearable data is processed on your device.

Yes — anytime, in one tap: Settings → Account → Delete Account. That permanently removes your account and associated data from our active systems.
