H2O Flow – Privacy Policy

Last updated: 7 May 2026

Overview

H2O Flow is a Chrome browser extension that helps you track daily water intake and receive hydration reminders. This policy explains how the extension handles your data.

Data we collect

H2O Flow does not collect, transmit, or share any personal data. All information is stored exclusively on your device using the browser's built-in chrome.storage.local API.

The following is stored locally on your device only:

• Your daily hydration goal (ml)
• Your chosen reminder interval
• Your notification message preference
• Your drink log (timestamps and ml amounts you enter)
• Your sound and notification style preferences

Data we do not collect

• No personally identifiable information
• No health or medical data sent to any server
• No browsing history or website content
• No location data
• No analytics or telemetry

Third-party services

H2O Flow loads the Lexend font from Google Fonts for display purposes. This is a standard CSS stylesheet request; no personal data is passed. Please refer to Google's Privacy Policy for details on their font service.

Data sharing

We do not sell, trade, or transfer your data to any third party. Your data never leaves your device.

Data deletion

Uninstalling the extension removes all locally stored data. You can also clear the data at any time by resetting Chrome's extension storage or uninstalling and reinstalling.

If this policy changes, the updated version will be published at this URL with a revised date.
