Privacy Policy - Deep Breath

Deep Breath - Breathing Exercise

Last updated: October 20, 2026

This Privacy Policy is provided in English only.

Introduction

This Privacy Policy describes how Deep Breath (“we”, “our”, or “the app”) collects, uses, and protects your information when you use our mobile application.

Information We Collect

1. Analytics Data

The app uses Firebase Analytics to collect anonymous usage data to improve the app experience:

• App usage patterns and feature interactions
• Device type and operating system version

This data is collected automatically and cannot be used to identify you personally.

2. Local Data

The following data is stored only on your device and is never transmitted to our servers:

• Breathing session history and statistics
• App settings and preferences
• Reminder settings

On iOS, if you used the app before Deep Breath Plus was introduced, a flag saying so is kept in your own iCloud (key-value storage) so the Plus features stay free for you on a new device. We cannot read your iCloud. On Android, the same flag is kept in the app’s local settings and moves to a new device only through Android’s own device backup.

3. Apple Health (iOS, optional)

If you turn on Apple Health in Settings, each finished session is written to Apple Health as Mindful Minutes. On Apple Watch, the app asks for the same permission and runs a Mind & Body workout session so the guidance keeps going while your wrist is down. The app only writes to Apple Health; it never reads your health data and never sends it anywhere.

Information We Do NOT Collect

• Personal information (name, email, phone number)
• Location data
• Photos, videos, or files
• Contacts or calendar data
• Health data (we never receive anything the app writes to Apple Health)

Third-Party Services

Our app uses the following third-party services:

• Firebase Analytics (Privacy Policy)
• Apple StoreKit (iOS) / Google Play Billing (Android) - For in-app purchases, handled entirely by Apple or Google

Advertising

Deep Breath does not display any advertisements. We do not use any advertising SDKs and do not use the Advertising ID.

In-App Purchases

Deep Breath offers one optional in-app purchase, Deep Breath Plus: a single payment, not a subscription, that unlocks guidance that keeps going with the screen off, every ambient sound, your own breathing pattern, widgets, and the Apple Watch app. Five breathing presets, every session length, history, and reminders are free.

Purchases are handled entirely by Apple (App Store) or Google (Google Play). We never see or store your payment details. The app only receives, and keeps on your device, whether the purchase is active.

Data Security

Your local data is stored securely on your device. We do not have access to this data. Analytics data is handled by Google according to their security standards.

Children’s Privacy

Our app is not directed to children under 13. We do not knowingly collect personal information from children under 13.

Your Rights

• Delete local data: Uninstalling the app removes all locally stored data

Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the “Last updated” date.
