What does "Protected" / "Unprotected" mean?

Protected means protected against pregnancy specifically — condoms, the pill, other contraception. It's not about STI or UTI protection. Ebbl tracks it this way because it's a cycle app, not a sexual-health app, and that one distinction matters for reading your own history correctly later.

Why doesn't Ebbl show ovulation or a fertile window?

On purpose. Ebbl doesn't calculate ovulation or a fertile window, and it won't tell you when you're more or less likely to conceive — that's fertility-app territory, and it's not what Ebbl is for. Logging whether you had sex, and whether it was protected against pregnancy, is a different thing: it's just another health data point, the same as noting caffeine or alcohol — useful for spotting your own patterns and for a GP, not for planning around ovulation.

My prediction looks different from another app I use — why?

Ebbl predicts your next period purely from the period start (and, once you add them, end) dates you've logged inside Ebbl — nothing gets pulled in automatically from Fitbit, Google Health, or anywhere else. With only a couple of logged periods, that's a small-sample average, so it can shift around; it gets steadier the more real cycles you log.

How does Ebbl learn my real period length?

Tap "Period ended today" on the last day of flow, or backfill it any time under "Manage cycle dates" on the Today tab. Once you've got a couple of real start-and-end pairs logged, Ebbl uses your real average instead of a guess — and each cycle's own real length, where you've logged one, instead of one number applied to everything.

Can I bring in data from Fitbit or Google Health?

Not automatically, no. Google's own API for this is write-only by design — apps can add data to it, but nothing (Ebbl included) can read menstrual data back out. Fitbit's developer API has never exposed it either. Anything Ebbl knows about your cycle has to come from what you log directly in Ebbl.

Why does Ebbl ask about PMDD and perimenopause at signup?

Because most period trackers treat both as rare edge cases, and they're really not. Your answers currently adjust what the app shows you — like unlocking a perimenopause symptom row in check-in — they don't yet change predictions, but that's on the list.

Where does my data actually live? Can I use Ebbl on more than one device?

Yes. Your login, onboarding answers, and your day-to-day period dates and check-ins all save to your account, so logging in on your phone, your laptop, or someone else's device shows your real history, not a blank slate. Your browser also keeps a local copy for speed and for briefly working offline. Full detail in the Privacy Policy.

What is "Download GP letter"?

It's a button on the Patterns tab that turns your logged data into a ready-to-print "To whom it may concern" letter, on Ebbl letterhead, that you can hand to your GP or bring to an appointment. It covers how many periods you've logged and how regular they are, what Ebbl tracks and how, any pattern Ebbl has spotted in your symptoms, and — if you've told Ebbl you think you might have PMDD or be in perimenopause — a plain statement of that, plus a detailed breakdown of the relevant symptoms you've logged, including how many of your worst days fell in the luteal phase (the second half of your cycle, after ovulation), since that timing is often the clue a GP is looking for. It's generated fresh from your real data every time you download it, and it's clearly marked as not a diagnosis — just a clear, dated summary to save you trying to describe weeks of symptoms from memory in a ten-minute appointment.
