Zentrail: Mindful Space

Zentrail is a private, offline mindfulness and reflection app designed to help you build a simple daily moment of calm.

Use Zentrail to check in with your mood, practice guided box breathing, write private journal entries, and explore mindfulness prompts—all directly on your Android device.

HOW ZENTRAIL WORKS

• Mood Check-in
Quickly record how you feel using five simple mood states: Radiant, Calm, Neutral, Fatigued, and Anxious. You can also add contextual tags to give your check-in more detail.

• Guided Box Breathing
Follow a visual 4-4-4-4 breathing pacer through four repeating phases: inhale, hold, exhale, and hold. The visual guide helps you maintain a consistent breathing rhythm during your practice.

• Private Reflection Journal
Write personal thoughts, reflections, or notes in the built-in journal. Your journal entries are stored locally on your device and are not uploaded to Zentrail servers.

• Mindfulness Prompts
Explore daily wisdom prompts and reflection questions designed to encourage mindful pauses and regular self-reflection.

• Streaks
Track your mindfulness habit with simple streak information and use it as a way to maintain consistency.

PRIVATE BY DESIGN

Zentrail is designed to work without an account or cloud service.

• Works offline
• No account or login required
• No advertising
• No analytics SDKs
• No tracking SDKs
• No cloud synchronization
• No internet access is required for core functionality
• User-created journal and mood data remains on the device

Zentrail requests no Android runtime permissions. Your locally stored information is kept within the application's private storage area provided by Android.

YOUR DATA

Zentrail does not require you to provide a name, email address, phone number, or other personal information to use the app.

Mood entries, journal content, preferences, and other information you create within the app are stored locally on your device. Zentrail does not provide a cloud backup service or automatically transfer this information to a remote server.

Because your information is stored locally, clearing the app's storage or uninstalling the app can permanently remove locally stored data. Consider this before clearing storage or uninstalling the application.

A SIMPLE MINDFULNESS TOOL

Zentrail is intended as a self-reflection and mindfulness tool. It is not a medical device and is not intended to diagnose, treat, cure, or prevent any medical or mental health condition.

Take a moment for yourself with Zentrail—check in, breathe, reflect, and build a mindful daily habit.
