Setting up your cycle profile in the Web App

Your cycle profile is the foundation Belle builds everything else on. Before the Web App can show you patterns, predictions, or correlations, it needs the three things only you can tell it: where you are right now, what you’re tracking, and what you want to understand.

What the cycle profile is

It’s the set of starting facts Belle uses to interpret your data. The Ring measures your biometrics around the clock, but biometrics alone don’t tell Belle whether you’re on day 4 or day 24, or whether the question on your mind is PMDD, perimenopause, or PCOS. Your cycle profile fills that gap. It’s the difference between a stream of numbers and a reading that means something for your cycle.

Setting it up

Open the Web App and go to Profile → Cycle profile. You’ll answer three questions:

• Where are you in your cycle right now? Enter the first day of your last period, or tell Belle you’re not currently cycling (pregnant, postpartum, on continuous contraception, or post-menopause). An estimate is fine — Belle refines this as it learns you.
• What are you tracking? Pick the conditions or questions that brought you here: PMDD, perimenopause, PCOS, general cycle patterns, or fertility awareness. This tells Belle which framework to apply.
• What do you want to understand? This shapes which insights surface first.

You can change any of these later. Nothing here is locked in.

What happens after

Belle doesn’t announce your phase or predict your period on day one. It can’t yet — and an app that pretends to is guessing. The textbook 28-day cycle averages closer to 29.3 in reality, with a range of 21–35 days, and your cycle is its own thing. So Belle starts listening. Over 2–3 cycles, the Web App learns your baseline and begins surfacing the patterns specific to what you’re tracking.

If you set perimenopause as your focus, Belle stages it against STRAW+10, the standard clinical framework for the menopause transition. If it’s PMDD, the app works from the PSST and DRSP — the same symptom screening tools your clinician uses. Naming the instrument is why your data holds up in front of a doctor later.

Keeping it current

Revisit your cycle profile whenever something shifts — a new symptom, a contraception change, a life stage. The more accurate your starting point, the sharper Belle’s reading.
