Sipling collects, stores and shares no personal data.
Everything you enter — your height, weight, age, what you drink, your trees — stays in your phone's own storage. It is never sent to us or to anyone else, because the app has no permission to access the internet.
Sipling has no server. You are never asked to create an account. Your advertising ID is not read. No analytics or crash reporting tools are used.
| Data | Where it lives | Why |
|---|---|---|
| Profile: sex, age, height, weight, activity level, waking hours | On your phone only | To calculate your daily water goal |
| Your drinks: amount, drink type, time | On your phone only | To show your progress, your streak and your forest |
| Preferences: reminder times, cups, theme | On your phone only | To run the app the way you want |
You can erase all of it at any time with Settings → Reset all data. Uninstalling the app does the same. There is no copy on our side, so you never need to send us a deletion request.
An optional feature you can enable in Settings writes the water you drink to Android's shared health record (Health Connect). This feature is off by default and nothing is written until you turn it on and grant permission.

Required by Android's work manager so the home screen widget can run in the background. They do not grant internet access. |
The app has no INTERNET permission. Location, camera, microphone,
contacts and file permissions are not requested either.
Sipling is suitable for all ages and, because it collects no data at all, it collects no data from children either.
If this policy changes, this page is updated and the date above changes. If advertising or in-app purchases are added, data processing will change and this policy will be updated before that release.
