Why women switch to Dawn Phase
Your period data belongs to you
Flo has faced scrutiny for data sharing. Clue shares anonymised data with research partners. Dawn Phase is free — and your cycle data is never sold, shared, or used to train AI. Ever.
Built for real cycles, not just 28 days
Most apps assume a textbook cycle and produce wrong predictions when yours doesn't match. Dawn Phase predicts from the median of your own logged cycles — never a fixed 28 — and was built specifically for PCOS and perimenopause users.
Bring data to your next appointment
Period Tracker, Flo, and Clue have no doctor export. Dawn Phase generates a PDF report you can actually bring to your GP or specialist — with your full symptom history across cycles.

Common questions
How is Dawn Phase different from Flo or Clue?
Dawn Phase never sells your data — that's the structural difference. We also build predictions from the median of your own logged cycles rather than a 28-day default, and show none at all rather than a made-up date when there is nothing of yours to build one from. On top of that: doctor-ready PDF exports and a dedicated perimenopause mode. Flo and Clue monetise through advertising and data partnerships; Dawn Phase is free and keeps your cycle data private.
Do you sell my data?
No. Ever. We have no data brokers, no third-party trackers, and we don't train AI models on your data. Dawn Phase is free to use, and your private cycle data is never part of the deal.
Does it work for perimenopause, PCOS, or irregular cycles?
Yes — this is what we're built for. An interval of up to about four months counts as a real cycle rather than an error, predictions come from the median of your own logged cycles instead of a fixed 28, and there is a dedicated perimenopause mode with its own tracking view and insights. Most period apps assume a textbook 28 days and break when yours doesn't match.
Can I export to my doctor?
Yes. From Settings, one tap generates a one-page PDF with your cycle lengths, symptom clusters, and bleeding pattern over the last 90 days — designed to be readable in under a minute. Print it or email it before your appointment.
What if I don't have my period yet, or my periods are irregular?
Dawn Phase works without regular periods. You can log day 1 whenever it happens, and log spotting and symptoms in between whether or not a prediction exists. It's also honest when it doesn't know: with no completed cycle yet it shows your cycle day and no predicted date, a prediction built on one or two cycles says so, and once you are more than three weeks past your own predicted date it pauses predictions rather than keeping a count running.
Is there an app, or is it web only?
Dawn Phase is a web app that works in any modern mobile browser. Add it to your home screen and it behaves like a native app — works offline, full-screen, app-icon. No App Store install required, no app updates to wait on.
Is Dawn Phase really free?
Yes. Cycle tracking, phase predictions, symptom logging, insights, and doctor PDF export are all free with an account — no credit card, no trial countdown, and no read-only lockout. Your data is always yours to export.
What happens to my data?
Your data stays yours. Export it anytime from Settings as CSV or a doctor-ready PDF, and deleting your account removes it for good. We never sell or share it.
