About

DotDiary

Read full description

DotDiary is a private period and cycle tracker that keeps your data where it belongs — in Apple Health on your iPhone. No account. No ads. No tracking. No subscription. Most trackers send your most personal data to their servers. DotDiary doesn't. Everything you log — periods, symptoms, fertility signs — is saved straight into Apple Health. DotDiary keeps no copy, has no login, and makes no network calls. Delete the app and your data stays safe in Health. WHY DOTDIARY • Private by design — your cycle never leaves your phone • No account, and no ads, ever • A one-time purchase for Pro — never a subscription • Calm, clean, and discreet TRACK WHAT MATTERS • Log your period with a single tap • Predictions with an honest confidence range — never falsely precise • Symptoms, moods, and fertility signs • A private journal note for any day • A calendar and trends view of your whole history CHANGING CYCLES — A PERIMENOPAUSE MODE (FREE) When your cycles start changing, most trackers break — predictions turn into noise. Switch DotDiary to Changing Cycles (you choose; the app never decides for you) and it describes instead of predicts: days and months since your last period, your recent cycle range, and a plain-language guide to the transition. Pro adds a month-by-month chart of hot flashes, night sweats, sleep and mood — and a doctor-ready PDF report that turns your next appointment from guesswork into a conversation. SWITCHING FROM FLO OR CLUE? Bring your history with you. DotDiary imports a Flo or Clue CSV export — free — and writes it into Apple Health, so you start with your real cycle instead of a blank slate. DOTDIARY PRO — one-time purchase • Month-by-month symptom chart for changing cycles • Your own custom symptom tags • Symptom patterns by cycle phase • A doctor-ready PDF report • Partner summary sharing • iCloud backup of your private notes Buy once and it's yours forever — and future Pro features arrive free. DISCRETION Pick a neutral app icon and turn on Face ID / passcode lock. iOS can also require Face ID to open — or completely hide — any app. UNDERSTAND YOUR CYCLE A built-in guide explains the four cycle phases, the difference between the follicular and luteal halves, and the hormones behind them — all in plain language. Available in English and French. DotDiary is not a medical device. Cycle predictions are estimates only and must not be used for contraception or conception planning. Fertility signs are logged to Apple Health; DotDiary does not predict fertile days.
