Effective Date: February 8, 2026
Deep Flow ("we," "our," or "us") is committed to protecting the privacy of our users ("you"). This Privacy Policy explains how we collect, use, and safeguard your information when you use our breathing exercise mobile application (the "App") available on the Google Play Store.
By using the App, you agree to the collection and use of information in accordance with this policy.
We prioritize your privacy. We do not knowingly collect, store, or share your name, physical address, or phone number. However, to provide our services and maintain the App effectively, we utilize third-party service providers that may collect certain data.
Deep Flow is a local-first application.
Health Data: All breathing statistics, session times, and exercise history are stored locally on your device. We do not transmit this data to external servers.
User Accounts: The App does not require account creation, ensuring your usage remains private to your device.
The App uses third-party services that collect information used to identify your device for analytics and advertising purposes. This includes:
Device Identifiers: Google Advertising ID (GAID).
Device Information: Model, operating system version, and general network information.
Approximate Location: Derived from IP address to ensure ads are relevant to your region.
Crash Logs: Data related to app stability and performance errors.
We partner with the following entities to facilitate our App's functionality and monetization. These parties have their own privacy policies governing their use of your data.
We use Google AdMob to display advertisements, allowing us to offer the App for free.
Google AdMob uses the Advertising ID from your device to serve personalized ads based on your interests and demographics.
Opt-Out: You can opt-out of personalized advertising by visiting your Android settings (Settings > Google > Ads > Delete advertising ID) or via Google's Ad Settings.

We use Firebase Analytics and Crashlytics to improve App stability and user experience.
This service collects anonymized data on how the App is used (e.g., screen views, session duration) and reports regarding app crashes.

If you are located in the European Economic Area (EEA), our legal basis for collecting and processing personal data (via our third-party partners) depends on the specific context:
Consent: We ask for your explicit consent to show personalized ads when you first launch the App (via a Consent Management Platform).
Legitimate Interests: For non-personalized ads and analytics required to maintain App security and performance.
You have the right to opt-out of data collection by uninstalling the App.
Under the California Consumer Privacy Act (CCPA), you have the right to opt-out of the "sale" of your personal information. In digital advertising, "sale" may include the sharing of device identifiers with ad networks.
How to Opt-Out: You may adjust your device settings to "Limit Ad Tracking" or use the privacy settings provided within the App's menu to manage your ad preferences.
You have the right to access, correct, or delete your personal data. Since Deep Flow does not store your data on our servers, you may exercise these rights by contacting our third-party partners (Google) directly or by resetting your device's Advertising ID.
Deep Flow is a wellness tool, not a medical device. The breathing exercises and techniques provided in this App are for relaxation and mindfulness purposes only. They are not intended to diagnose, treat, cure, or prevent any medical condition.
Consult a doctor before starting any new breathing practice, especially if you have a history of cardiovascular or respiratory issues.
If you experience dizziness, shortness of breath, or discomfort, discontinue use immediately.
Our services are not directed to anyone under the age of 13. We do not knowingly collect personal identifiable information from children under 13. If we discover that a child under 13 has provided us with personal information, we immediately delete this from our servers. If you are a parent or guardian and you are aware that your child has provided us with personal information, please contact us.
We may update our Privacy Policy from time to time. Thus, you are advised to review this page periodically for any changes. We will notify you of any changes by posting the new Privacy Policy on this page. These changes are effective immediately after they are posted.
If you have any questions or suggestions about our Privacy Policy, please do not hesitate to contact us.
