What we collect.
What we don't.
Plain English. Updated when anything material changes. Last revised May 2026.
The short version
Dew is a period tracker that lives only on your iPhone. We don't run a server that stores your cycle data. We don't have an account system. We don't show ads. We never sell your data to anyone, because there's nothing about you to sell — we have no way of knowing who you are.
What stays on your phone
- 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.
iCloud sync (optional, off by default)
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.
On-device AI reflections
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. Nothing is sent to a server.
Anonymous install metrics
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.
What we never do
- 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.
Notifications
Period reminders are scheduled by your iPhone, locally. There is no notification server. We never see when you opened the app or whether a reminder fired.
Apple Health (optional)
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.
Deleting everything
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.
Email forwarding
If you write to hello@trydew.app, 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.
Children
Dew is intended for users 13 years of age and older. We don't knowingly collect anything from anyone younger.
Contact
Questions, concerns, or corrections — hello@trydew.app. One person reads every note.
This page is what we believe to be true today. If anything changes in a way that affects you, we'll tell you in the app first.
