Six factors are combined: your chronotype, the three biorhythm cycles (physical, emotional, intellectual), geomagnetic activity from the NOAA Kp index, local weather and atmospheric pressure with its stability, the lunar phase, and a time-of-day modifier. Each factor is weighted differently depending on the kind of event you are placing — focused work and time with people do not want the same hour.

Your date of birth, for the biorhythm cycles and the initial chronotype estimate. Optionally your city, so weather and pressure can be looked up locally. Everything else is optional.

No. Accepted slots are written into a separate calendar called “MomentumX”. Your own calendars are read to find free time and are never modified.

Sleep samples are read-only and processed entirely on your device to find your mid-sleep point. They are never uploaded to our servers or to any third party, and they are removed when you disconnect sleep data in Profile or delete the app.

Open the app → Profile tab → “Restore Purchases”. Your subscription is restored automatically if you are signed in with the same Apple ID that bought it.

iPhone Settings → your Apple ID → Subscriptions → MomentumX → Cancel Subscription. The subscription stays active until the end of the period you already paid for.

Profile → Delete Account. There is a 30-day grace period during which signing back in cancels the deletion. After 30 days everything is permanently erased. Cancel any active subscription through Apple separately — billing is not ours to cancel.
