💡 Summary: Marina is designed with a Privacy-First architecture. You do not need to create an account to use the app. Your hydration logs, targets, and streaks stay on your device and in your personal Apple iCloud Private Database. We do not sell your data, we do not use third-party advertising, and we cannot read your personal logs.

1. Introduction

Welcome to Marina ("we", "our", or "us"), developed by Ali Atakishiyev. Your privacy is a fundamental priority in how we build and maintain the app.

This Privacy Policy explains how Marina handles information when you use our mobile application and related widget extensions for iOS (collectively, the "App"). By using Marina, you agree to the collection and use of information in accordance with this policy.

2. Information We Collect and How We Use It

Marina operates on data minimization: we only process information necessary to deliver hydration tracking and seamless user experience.

A. Hydration & Wellness Inputs (Entered by You)

When you use Marina, you may log and configure:

• Water intake records: Volume (milliliters or fluid ounces), container type, timestamps, and optional notes.
• Goals & targets: Daily hydration targets, preferred units of measurement, and streak progress.
• Onboarding lifestyle inputs: Approximate daily activity level (e.g., Light, Moderate, High) and hydration motivation (e.g., Energy, Fitness, Mindful Habit), used solely on-device to suggest your recommended daily water goal.

How it is used: To display your daily progress, render interactive gauge visualizers, calculate hydration streaks, and present summary information in your iOS widgets.

B. No Account Required

• We do not require registration, sign-up, or login.
• We do not collect your name, email address, phone number, contacts, or passwords.
