Good questions.

They are estimates, and they calibrate to you. Photo and calorie burn estimates get sharper as you log more and as MinervaOS learns from your real data. Always sanity-check important numbers; it is a self-tracking tool, not a measuring device.

No. MinervaOS is for informational and educational self-tracking only. It doesn't diagnose, treat, or prevent anything, and it isn't a substitute for a doctor or dietitian. Consult a qualified professional before making health, diet, or exercise decisions.

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

No. MinervaOS works with just your phone, and connecting nothing at all is perfectly fine. We do recommend at least connecting Apple Health so your steps and workouts feed your burn, and adding an Apple Watch 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 Apple Watch 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.

Not yet. MinervaOS is iPhone-only for now.
