What we collect.
What we don't.

Dew is a period tracker that lives only on your iPhone. No one but you — not even us — can ever see what you log. We keep no copy of your data; it isn't possible for us to, and we'd never want to. There's no account, no ads, and nothing about you to sell — we have no way of knowing who you are.

• Your period start and end dates
• Cycle length history
• Symptom and mood logs
• Custom mood and symptom labels
• Notes you write
• App preferences (appearance, reminder times, settings)

All of this is written to a local store on your iPhone. It does not leave the device unless you choose to turn on iCloud sync.

If you turn iCloud sync on, your data is copied into your own private iCloud container — encrypted so only your Apple devices can open it. We don't see it. Apple can't read it. Disable it any time; the cloud copy is then removed.

When the app writes you a small reflection about your cycle, it uses Apple's on-device language model — the one that ships with iOS. Your prompts, your data, and the model's output all stay on your iPhone. No one but you ever sees it.

Like every iPhone app, Apple reports anonymous install and crash counts to us through App Store Connect. These tell us things like "200 people installed Dew last week" or "5 people experienced a crash on iOS 26.4." They do not tell us who you are, where you are, or what you logged.

• Show ads, anywhere in the app, ever.
• Sell, rent, or share your data with anyone.
• Use third-party trackers, advertising IDs, or fingerprinting.
• Require an account, email, or login.
• Train AI models on your data.
• Hand data to law enforcement — because we don't have it.

Period reminders are set by your iPhone, locally — nothing passes through us. We never see when you opened the app or whether a reminder fired.

If you turn on Apple Health sync, period dates flow one-way from Dew into Apple Health. Off by default. Off again with one tap.

If you choose to share your next-period date with one person, it goes through your own iCloud — end-to-end, no Dew server in between. They see only what you choose. Revoke from Settings any time and the connection is gone for good.

Free: a plain CSV of every entry, generated on your iPhone. Pro: a clean PDF report formatted for a clinician. Both options exist so your history is yours to keep, move, or print — there is no lock-in.

Dew respects the iOS system settings automatically — VoiceOver, Dynamic Type, Reduce Motion, Increase Contrast, and Bold Text. Nothing extra to enable; the app changes when your system does. If something feels off with your assistive setup, write to us and we'll fix it.

Open Dew → Settings → Delete all data. This clears every entry from your phone and removes the iCloud copy too. There is no other place where it existed.

If you write to [email protected], your email lands in the maker's inbox. We read it, reply if helpful, and don't store it elsewhere or add you to any mailing list.

Dew is intended for users 13 years of age and older. We don't knowingly collect anything from anyone younger.

Questions, concerns, or corrections — [email protected]. One person reads every note.
