HydroFit is a general-wellness water-intake logging application. It lets you manually record water intake, choose a daily water-intake goal, monitor progress toward that goal, review local history and trends, configure reminders and schedules, earn local achievements, and use Android home-screen widgets.
HydroFit does not measure your biological hydration. Its battery, forecasts, trends, and insights represent user-entered water intake and progress toward a user-selected goal.
HydroFit is not a medical device and does not provide medical advice. It should not be used to diagnose, treat, cure, prevent, or manage any medical condition. HydroFit does not detect dehydration or determine an individual's medical water requirements.
If you have questions about hydration, medication, fluid restrictions, pregnancy, kidney or heart conditions, athletic needs, or any other health matter, consult a qualified healthcare professional. Do not disregard professional medical advice because of information shown by HydroFit.
HydroFit stores app information locally in app-private storage on your device. Depending on the features you use, this may include:
Water-intake logs and today's logged intake
Daily goals and goal schedules
Wake and sleep schedules
Reminder preferences and locally scheduled notification metadata
Streaks, achievements, history, trends, forecasts, and insight inputs or outputs
Quick-log choices and temporary undo or redo information
Language, theme, unit, sound, visual-effect, and other app settings
A limited local indicator of Google Play Premium entitlement
The minimal local information required to render and operate HydroFit widgets
This information is used on the device to provide HydroFit's features.
HydroFit has no Plumb Apps account system, cloud synchronization service, or Plumb Apps backend. Through HydroFit, Plumb Apps does not receive your hydration logs, water-intake records, goals, schedules, reminders, streaks, achievements, history, forecasts, trends, settings, or widget information.
HydroFit does not intentionally include advertising, analytics, crash-reporting, or custom tracking services. It does not create an Expo push token and does not send reminders through an Expo or Plumb Apps push server.
You do not create or sign in to a HydroFit or Plumb Apps account. HydroFit can be used after completing local onboarding on your device.
Because HydroFit does not provide an online account, there is no remote HydroFit account record to delete. The in-app Delete All Data control removes HydroFit's local app data as described below.
HydroFit offers a lifetime Premium purchase through Google Play Billing. Google Play processes the transaction under Google's own terms and privacy practices. HydroFit does not receive or store your payment-card or bank-account details.
HydroFit receives purchase-status information from Google Play so it can unlock Premium, acknowledge a completed purchase, handle pending purchases, and restore ownership. A limited Premium-entitlement record is cached locally on your device so Premium can remain available when the device is temporarily offline. This local record may include the product, provider, status, acknowledgement state, and limited transaction-related metadata returned by the billing integration. It is not sent to Plumb Apps.
Deleting HydroFit data clears this local entitlement cache, but it does not cancel, refund, transfer, or erase purchase ownership held by Google Play. If Google Play still reports that you own Premium, HydroFit may restore Premium without restoring deleted water-intake or wellness data.
For information about Google's processing, review the Google Privacy Policy and applicable Google Play terms.
HydroFit reminders are scheduled locally on your device. HydroFit requests Android notification permission only when notification features require it. No push token is created and reminder schedules are not sent to Plumb Apps.
Reminder messages are general prompts and do not contain your water-intake amount, daily goal, profile information, or a medical assessment. Depending on your Android lock-screen and notification settings, reminder content may be visible to anyone who can view your lock screen. You can disable reminders in HydroFit or change notification visibility in Android settings.
Delete All Data cancels scheduled HydroFit notifications and dismisses delivered HydroFit notifications before local app data is removed.
HydroFit widgets use app-private local storage to display information such as logged intake, daily-goal progress, quick-log controls, streak information, forecasts, insights, or calendar history, depending on widget type and Premium status.
Widget content may be visible to anyone who can view your unlocked home screen. Some widget controls can add, undo, redo, or request manual water logs without first opening the main app. Android and launcher behavior determine how widgets appear and who can interact with them.
HydroFit stores a minimized widget-specific copy of required information. It does not place billing transaction IDs, purchase timestamps, billing acknowledgement details, or unrelated app state in widget storage. Delete All Data clears widget state and pending widget actions and immediately resets installed widgets to an empty state.
HydroFit's local information remains on your device until one of the following occurs:
You change or remove it through app features
You use Settings > Delete All Data and complete the confirmation
You clear the app's storage through Android settings
You uninstall HydroFit, subject to Android and device-manufacturer behavior
Delete All Data removes the primary HydroFit storage record and locally stored water intake, goals, schedules, reminder preferences, streaks, achievements, undo and redo data, forecast and trend data, language, theme, unit and other settings, the local Premium cache, widget state, pending widget actions, pending manual-log requests, and stale notification metadata. It also cancels locally scheduled HydroFit notifications and returns the app to onboarding.
Deletion is local to the device. Google Play may retain purchase, payment, and account information under Google's own policies and legal obligations.
Uninstalling HydroFit normally removes its app-private local data and widgets under Android's standard application-storage behavior.
HydroFit sets Android backup to disabled and supplies rules excluding app files, databases, preferences, widget state, notification information, Premium cache, and wellness history from Android cloud backup and device transfer. However, Plumb Apps cannot guarantee the behavior of every Android version, device manufacturer, launcher, migration tool, rooted device, custom operating system, or third-party backup utility. Manufacturer or system tools outside HydroFit's control may behave differently.
HydroFit relies on Android application isolation, app-private storage, Android's device security, and the security controls configured on your device. Widget storage uses Android private application preferences.
HydroFit does not add separate application-level encryption to its local state. A person who can unlock, compromise, root, or otherwise gain sufficient access to your device may be able to view local app or widget information. Use a device lock and appropriate lock-screen notification settings if this information is sensitive to you.
HydroFit's confirmed release network service is Google Play Billing. Google Play and underlying Google services may process purchase, app, device, security, diagnostic, or transaction information as necessary to operate their services under Google's policies.
HydroFit also relies on Android system features for local notifications, app widgets, application storage, and opening the public privacy-policy link in your browser. Plumb Apps does not operate a server for these functions.
HydroFit's intended minimum age is 13 years old. HydroFit is a general-wellness utility and is not designed or presented as a child-directed educational app, game, or social service.
Parents or guardians should decide whether HydroFit is appropriate for a minor and should supervise any health-related decisions. HydroFit does not provide an online account, social interaction, user-generated content sharing, or targeted advertising.
Plumb Apps is based in Greece (Hellenic Republic). HydroFit primarily processes user-entered app data locally on the device. Google Play may process purchase and service information in countries where Google or its service providers operate, subject to Google's terms and privacy policy.
You are responsible for using HydroFit consistently with laws and professional guidance applicable to you. Nothing in this policy limits rights that cannot legally be limited in your jurisdiction.
Plumb Apps may update this Privacy Policy when HydroFit's features, legal requirements, or data practices change. The updated policy will show a revised "Last updated" date. Material changes should be reflected in the publicly available policy before or when the related app change is released.
