Dew: Private Period Tracker

Calm period tracker. Lives on your iPhone — not on a server. No account, no ads, no data sold. By design.

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, no data ever sent to our servers — because there are no servers.

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 (coming soon)

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.
