My reminders don't arrive. What can I do?
Check that notifications are allowed for Water Reminder in your phone's settings, and that reminders are on in the app. On Android, some phones stop apps in the background to save battery: in your phone's battery settings, allow Water Reminder to run in the background. On iPhone, a Focus mode can silence reminders.
I subscribed to Premium but don't see it. How do I restore it?
Open Settings and tap **Restore purchases** on the Premium card at the top, or tap **Restore** on the plans screen. Make sure your phone is signed in to the same Apple or Google account you subscribed with, and that you're online.
How do I cancel or change my subscription?
On iPhone, open Settings, tap your name, then Subscriptions. On Android, open Google Play, tap your profile, then Payments & subscriptions, then Subscriptions. **Deleting the app does not cancel your subscription.** After you cancel, Premium stays active until the end of the period you paid for.
How do I ask for a refund?
Apple and Google process all payments, so refunds follow their policies. Ask Apple at [reportaproblem.apple.com](https://reportaproblem.apple.com), or Google Play from the order history in your account. We cannot refund store purchases ourselves.
I used the app before Premium. Do I get a free month?
Yes. People who used the app before Premium was introduced get one month of Premium for free, with a reminder one week before it ends. It needs no payment details and ends on its own, without any charge.
How does health sync work?
With Premium, turn on **Health Sync** in Settings, and the app writes the drinks you log to Health Connect on Android or to the Health app on iPhone. The app only writes: it never reads your health data.
Does the app work on my watch?
Yes, on Wear OS and Apple Watch: log a drink on your watch and it reaches your phone. Syncing your watch with your phone is part of Premium.
Will I lose my log if I delete the app?
Your drink log is stored on your phone, not in an online account, so we can't recover it from our side. Deleting the app may erase it.
How do I delete my data?
In the app, go to Settings › Danger zone › **Delete Account**: it deletes all your data on the device. All the details are on the [delete your account and data](/delete-account) page.
