Privacy Policy

On your device and in iCloud

HydroDrop does not collect, store, or share any personal data on any server of its own. Everything you enter, including your water intake, daily goal and reminder settings, is stored on your device using Apple's standard local storage.

If you are signed in to iCloud, your water log and preferences are also stored in your private iCloud account so they stay in sync across your devices. That data is protected by Apple's iCloud privacy terms and is never visible to us.

Apple Health

HydroDrop can add the drinks you log to Apple Health as dietary water. This is turned off until you turn it on in Settings, and iOS will ask your permission before HydroDrop can write anything.

Writing and reading are separate, and both are off until you turn them on. HydroDrop writes water, and caffeine if you turn on caffeine tracking. It reads nothing from Apple Health unless you connect Insights, and it can never see what other apps have written there beyond the four things listed below.

Insights is part of HydroDrop+. If you connect it, iOS asks your permission first, and HydroDrop then reads four things: your sleep, your resting heart rate, your workouts and your active energy. They are used on your device to show how they line up with the days you hit your water goal, and to suggest extra water on a day you worked out. None of those readings are saved by HydroDrop, synced to iCloud, shared with anyone, shown in a widget or sent to us, and they are never used for advertising. If you accept extra water after a workout, today's goal goes up, exactly as it does on a hot day, and that raised number is the only thing kept: on your device, and on your widget and watch for the rest of the day. Insights describes patterns in your own data. It is not medical advice. If you say no, everything else in HydroDrop works exactly as before.

What HydroDrop writes is the amount it counts towards your goal, so a coffee adds what it actually hydrates rather than the full cup. If you delete or edit a drink in HydroDrop, the matching Health entry is removed or replaced. Turning the setting off stops new drinks being added and leaves whatever is already in Health alone. You can remove it yourself at any time in the Health app, under Sharing, then Apps and Services, then HydroDrop.

Health data stays on your device and in your own Apple Health store, which is protected by Apple's privacy terms. It is never sent to us, and we have no way to see it.

Location and weather

HydroDrop+ can suggest drinking a little more on hot days. This is turned off until you turn it on, and iOS will ask your permission before HydroDrop can use your location.

When it is on, HydroDrop asks the device for a rough location, accurate to about a kilometre, and sends it to Apple's weather service to ask what the conditions are. That is the only thing it is used for. Your location is not stored, is not kept in your water log, and is never sent to us or to anyone else. Apple's privacy terms cover the weather request.

A suggestion only ever offers extra water for that day, and only if you accept it. Your saved daily goal is never changed on your behalf. Turning the setting off stops HydroDrop asking for your location at all.

Advertising

The free version of HydroDrop shows banner ads served by Google's AdMob, which funds HydroDrop's development so the app doesn't require a subscription to use. HydroDrop+ removes the ads, whether you subscribe or buy HydroDrop+ Lifetime.

In the European Economic Area, the UK and Switzerland, HydroDrop shows no ads and does not start Google's ad software. It works this out on your device from your App Store country and your device's region setting, and sends neither anywhere to do so.

HydroDrop asks Google for non-personalized ads only. The ads you see are chosen from context, such as the app you are using and your rough region, and not from a profile of you or of what you do in other apps and websites. HydroDrop does not ask for permission to track you, so iOS does not give your device's advertising identifier to the app or to AdMob.

To deliver and measure ads and to stop fraud, AdMob still receives general technical information, such as your IP address, your device type and whether an ad was shown or tapped. Google's privacy policy governs this data.

Earlier versions of HydroDrop asked for permission to track in order to show more relevant ads. Current versions do not use that permission. If you answered that prompt, you can review or reset it at any time in iOS Settings, under Privacy & Security, then Tracking.

Bug reports

If you use the Report a Bug feature in Settings, the app opens your device's Mail app with a pre-filled message containing basic diagnostic information (app version, iOS version, device model) and whatever you choose to write. This is sent directly from your device only if you tap Send. HydroDrop itself does not transmit this information anywhere.

In-app purchases

HydroDrop+ subscriptions and the one-time HydroDrop+ Lifetime purchase are processed entirely by Apple through the App Store. We never receive or store your payment information. Apple's privacy policy governs that data.
