Privacy Policy — Tummy Timer
Last updated: 5 October 2026
Tummy Timer is a baby feeding tracker for Android, published by Nafis Hasrat Arnob.
What the app stores
Everything you log is written to a database inside the app's own private storage on your device:
- Feeds — the time, whether it was breast, bottle or solids, and any amount, duration or note you add
- Pumping sessions and the freezer total
- Growth measurements — weight, height and the date
- Your baby's name, date of birth and sex, if you choose to enter them (the sex is used only to pick the right WHO growth curves)
- Your settings — the gap between feeds, the reminder mode, the theme, the country for the emergency number, whether the Solids button and tips are shown, and which tips you have already seen
Every one of these is optional except the feed times themselves, and none of it leaves your device. The app also keeps an automatic copy of this history in the same private storage, so your phone's own backup or a move to a new phone can bring it back, and the home screen widget keeps a copy of the next and last feed so it can show them.
What the app sends
Nothing. Tummy Timer has no internet permission. It cannot send your data anywhere, and it does not contain any analytics, tracking, advertising or crash-reporting service.
You can confirm this: put the phone in aeroplane mode and the app works exactly as it does otherwise.
The Parent FAQ and the tips on the Home screen link to the official pages they came from. Tapping a link opens it in your browser or the YouTube app, not in Tummy Timer, and nothing about you or your baby is sent with it. The emergency button opens your phone's dialer with the number filled in; the call is only made if you press call. In Settings, under About, the email address opens your own email app, and the developer's name opens their website in your browser; nothing is sent unless you choose to send an email.
Data we collect
None. We do not collect, receive, store, transmit, sell or share any personal information. We have no way to identify you, and no copy of your data exists anywhere but your own phone.
Permissions the app asks for, and why
| Permission | Why it is needed |
|---|---|
| Notifications | To show the reminder when the next feed is due |
| Run at startup | To restore a pending reminder after the phone restarts |
| Vibrate | So the reminder can vibrate if you choose that setting |
| View network connections, foreground service, prevent phone from sleeping |
Required by the Android background-work library that runs the Breast and Bottle buttons on the home screen widget, so a tap there records a feed even when the app is closed. None of these grants access to the internet. |
That last row is the complete list — if you inspect the app's permissions on your phone you will see those three alongside the first three, and nothing else. The internet permission is not among them, which is why the app has no way to send anything anywhere.
Tummy Timer deliberately asks for no storage permission. When you export a backup or a spreadsheet, Android's own file picker asks you where to save it and grants the app access to that one file only. When you restore a backup, the same thing happens in reverse.
Backups you create
If you use Export backup or Export spreadsheet, the file is written wherever you choose — a folder on your phone, a cloud drive, an email. Once it leaves the app it is yours, and it is governed by whatever service you saved it to, not by us. We never see it.
The "rate this app" prompt
After you have logged a number of feeds, the app may once ask whether you would like to rate it. That opens Google Play's own rating dialog, which is part of Play and not part of Tummy Timer. We do not see whether you rated it, what you rated it, or whether you dismissed it, and nothing about your feeds is involved. The app never asks again.
Android's own backup
Android may include the app's data in the device backup tied to your Google account, as it does for most apps. That is a function of your phone and your Google account settings, not of Tummy Timer, and it is covered by Google's privacy policy. You can turn it off in your device's backup settings.
Children's privacy
Tummy Timer is intended for use by parents and carers, who are adults. It is not directed at children and does not knowingly collect information from anyone. The app records information about an infant only because a parent chooses to type it in, and that information never leaves their phone.
Deleting your data
Everything lives on your device, so you are always in control:
- Delete individual feeds by swiping them away in History
- Replace the whole history with Restore backup in Settings
- Uninstalling the app removes the database and every setting with it
There is nothing for us to delete on your behalf, because we never had it.
Changes to this policy
If this policy changes, the updated version will be posted at this address and the date at the top will change. Since the app collects nothing, any change is likely to be a clarification rather than a change in practice.
