Privacy Policy

Welcome to Hydration Tracker, developed by Zavi Studio. We are committed to protecting your privacy. This policy explains how our Android app handles your information.

By using Hydration Tracker, you agree to the practices described in this Privacy Policy.

Information you enter into the app:

• Water intake logs — drink type, amount in ml, timestamp
• Personal settings — body weight, activity level, daily goal
• Reminder preferences — wake-up time, sleep time, interval

Information we do NOT collect:

• Name, email address, or any personally identifiable information
• Location data (GPS or network-based)
• Camera, microphone, or biometric data
• Contacts, call logs, or messages
• Payment or financial information
• Health data from Google Fit or Health Connect

• Water logs stored in a local Room (SQLite) database on your device
• Settings stored using Android DataStore on your device
• No data is transmitted to any external server
• Uninstalling the app permanently deletes all data

Hydration Tracker displays banner advertisements provided by Google AdMob. AdMob may collect certain device information to serve relevant ads.

AdMob may collect:

• Advertising ID (Google Ad ID)
• Device type and operating system version
• IP address (approximate location — country/region only)
• App interaction data for ad personalization

AdMob data collection is governed by Google's Privacy Policy:
https://policies.google.com/privacy

Hydration Tracker does not share any health, personal, or usage data with AdMob beyond what AdMob collects independently through its SDK.

No permission is used to collect or transmit your personal data.

Hydration Tracker sends local push notifications to remind you to drink water. These notifications:

• Are scheduled entirely on-device using Android AlarmManager
• Do not require an internet connection
• Only fire between your saved wake-up and sleep times
• Can be disabled anytime in app Settings or device notification settings

Hydration Tracker does not knowingly collect personal information from children under the age of 13. The app contains advertisements served by Google AdMob.

If you are a parent or guardian and believe your child has provided personal information through this app, please contact us immediately so we can take appropriate action.

Since all data is stored locally on your device:

• Delete individual water logs directly in the app by swiping
• Reset all data via device Settings → Apps → Hydration Tracker → Clear Data
• Uninstalling the app removes all data permanently

We do not retain any copies of your data on external servers because we never receive it.

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated "Last Updated" date at the top.

Continued use of the app after changes constitutes acceptance of the updated policy. We encourage you to review this page periodically.
