Dew: Private Period Tracker

A period tracker that respects your privacy — by design.

Your cycle lives on your phone and in your private iCloud. We can't see it. Neither can anyone else. No accounts, no logins — and nothing you log ever leaves your phone.


WHAT MAKES IT DIFFERENT

- On-device cycle predictions following FIGO 2018 medical guidelines
- Lock Screen Live Activity — day-of and days-from your cycle, at a glance
- Home Screen widgets in three sizes
- Two-way Apple Health sync — one source of truth
- Multi-profile support — track yourself and a partner, kept separate
- Partner sharing via secure iCloud


CALM BY DESIGN

- No notification spam — at most one gentle nudge a day, suppressed on days you've already logged
- No bright colors, no urgency, no exclamation marks
- Dark and light mode, both done right


PRIVACY, BY THE NUMBERS

- Zero third-party trackers
- Zero advertising SDKs
- Zero crash-reporting middlemen — only Apple's own MetricKit
- Anonymous, opt-out usage analytics — disable in Settings → Privacy


For everyone tired of period apps that treat their body as a data set.

Dew is free. The privacy promise is the product.

A note: Dew shows when your period is expected. It does not diagnose conditions or replace conversations with a doctor. Dew is general wellness — not a medical device.
