Nothing. Water Tracker does not collect, transmit, store, or share any personal information whatsoever.
All data you enter — your water intake logs, your daily goal, your unit preferences — is stored exclusively on your iPhone using Apple's on-device storage framework. This data never leaves your device and is never accessible to us or any third party.
We do not use any analytics tools, crash reporters, or telemetry services. We have no visibility into how you use the app, how often you open it, or anything else.
Water Tracker contains no third-party code that could collect data on our behalf. There are no advertising SDKs, no social media integrations, and no external services of any kind.
You do not create an account to use Water Tracker. We have no user database because there is nothing to store.
Water Tracker does not require an internet connection and does not make any network requests. It works entirely offline, always.
The home screen widget reads your water intake data directly from your device — the same local storage the main app uses. No data is sent to any server to power the widget.
Because we collect no data from anyone, Water Tracker is safe for users of all ages.
To delete all of your data, simply delete the app from your iPhone. All locally stored data is permanently removed when you do so. There is nothing on any server to delete because nothing was ever sent there.
If we ever change this policy, we will update the date at the top of this page. Given the nature of this app, we do not anticipate any meaningful changes.
