The two versions are the same app and this policy covers both. Where they differ, the section says which one it is talking about. The short answer is that the Android version does less: it has no sync, no purchases, and no server of anybody’s involved at all.
This describes what the app actually does, checked against its source code rather than against intentions.
Milk Hour stores the following on your device:
| Data | Examples |
|---|---|
| Baby | Name, birth date, sex — all optional, and asked for only when a feature needs them |
| Feeds | Time, duration, which breast, bottle amount, whether the milk was formula, expressed or donor |
| Sleep | Start and end times |
| Nappies | Time, and whether wet, dirty or both |
| Pumping | Time, duration and amount expressed |
| Solids, medicine, notes | Time and whatever you type |
| Growth | Weight, length and head circumference, with the date measured |
| Settings | Night-mode hours and dimness, reminder choices, which baby is selected |
A birth date and sex are stored only because the WHO growth standards are separate for boys and girls and indexed by age in days. Without them the app still records measurements; it simply cannot say where one sits. If you never use growth tracking, you never need to supply either.
On iPhone, the log lives in a database inside the app’s App Group container, which is shared with the Home Screen widget, the Lock Screen control and the Apple Watch app so that all of them show the same information.
On Android, it lives in the app’s own private storage, readable only by Milk Hour, and the home-screen widget and the Quick Settings tiles read that same database. It is excluded from Android’s Auto Backup, so it is not copied to your Google Drive and not carried across in a device-to-device transfer. Export is the way to move a log, and it is one tap.
There is no sync in the Android version. The log stays on the one device.
Sync is off until you turn it on, in Settings → iCloud.
When it is on, your log is mirrored to your own private iCloud database using your Apple Account. This is a feature of iOS called CloudKit. We have no access to that data, cannot read it, cannot recover it for you, and never receive a copy. It is governed by Apple’s Privacy Policy.
Sync reaches your own devices — your iPhone and your iPad. It does not reach a second parent’s phone, and the app says so on the same screen rather than leaving you to discover it.
You can remove that data at any time in iOS Settings → your name → iCloud → Manage Account Storage.
There is no Wear OS app. On iPhone, the watch app talks to your phone directly, over Apple’s WatchConnectivity, which is a link between two devices you own. Nothing goes through a server of ours. The watch holds only a small summary — the last feed, a running timer, which side is next, and today’s counts — and the phone keeps the real log.
If you switch reminders on, Milk Hour asks the system for permission to show notifications. Reminder times are worked out on your device from what you have logged, and only when there is a steady enough pattern to be worth interrupting you for. Nothing about them leaves the device.
On Android, while a feed, sleep or pump is running the app also shows an ongoing notification with a timer, so the elapsed time is readable without unlocking. It is drawn by the system from the start time and contains nothing beyond what is already on the screen.
Nothing is for sale in the Android version. There is no Plus tier, no subscription, no in-app purchase and no billing code in it. Every feature is free, including the ones that are paid on iPhone.
On iPhone, Milk Hour Plus is sold through Apple’s In-App Purchase. Apple handles the payment; we never see your payment details. Whether you currently hold a purchase is checked with Apple and stored on your device.
ACCESS_NETWORK_STATE, WAKE_LOCK,
RECEIVE_BOOT_COMPLETED and FOREGROUND_SERVICE permissions. They come from
the Jetpack library that schedules background work for the home-screen
widget, not from anything Milk Hour does with a network. The app still makes
no requests.You can export everything you have logged as a CSV file at any time, free, from Settings → Your data → Export as CSV. You can bring a log in from another app the same way — including a log exported from the other platform’s version, which writes the identical file. Deleting the app deletes its database from your device.
Milk Hour is used by parents and carers to record information about their own children. It is not directed at children and children do not use it. Because nothing is collected or transmitted, no information about a child is ever received by us.
Milk Hour is not a medical device and does not provide medical advice.
Growth percentiles are calculated on your device from the published WHO Child Growth Standards and describe where a measurement sits among healthy children of the same age and sex. They are not a diagnosis. Feed and sleep predictions are arithmetic over what you have logged, not a recommendation, and the app declines to predict when it does not have enough history rather than guessing.
Always speak to your health visitor, midwife or doctor about your baby’s health.
If this policy changes, the date at the top changes with it, and the updated policy is published here before the version of the app it applies to is released.

Milk Hour is licensed, not sold.
On iPhone and iPad, use of the app is governed by Apple’s Standard End User License Agreement. On Android, it is governed by the Google Play Terms of Service.
Milk Hour Plus exists only on iPhone and iPad. It is available there as a yearly auto-renewing subscription or as a single payment that never renews. Subscriptions renew unless cancelled at least 24 hours before the end of the current period, and are managed in iOS Settings → your name → Subscriptions. Any unused part of a free trial is forfeited when a subscription is purchased.
The Android version has no paid tier at all. Everything is free there, including trends, growth over time, the summary for your doctor and more than one baby. There is no plan to introduce one for the features that ship today.
On iPhone, everything the app needs to do at three in the morning — logging of every kind, which side is next, when the next feed is likely, reminders, the widget, the Lock Screen button, the Live Activity, night mode, the Apple Watch app, growth percentiles and CSV export — is free, and will not be moved behind the paywall in a later version.
The app is provided as is. It is a record-keeping tool. It is not a substitute for medical advice, and no decision about a child’s health should rest on it.
