Entra terms of use
Last updated: 17 August 2026
Acceptance
By downloading or using Entra, you agree to these terms. If you do not agree, do not use the app.
What the app does
Choose a focus, study, reset, or sleep session and shape the soundscape around the moment. The app is provided for personal planning and information. It does not guarantee a particular result.
Important information
Entra is a sound and workflow tool, not medical treatment. Binaural tones and ambient sound affect people differently. Do not use the app as a substitute for professional medical advice.
Subscriptions
Where offered, subscriptions are auto-renewing purchases through Apple. The price shown in the App Store applies to your storefront. Payment is charged to your Apple ID at confirmation; renewal occurs unless cancelled at least 24 hours before the current period ends. Manage subscriptions in your Apple ID settings.
Availability and liability
The app is provided on an “as is” basis to the maximum extent permitted by law. We are not responsible for decisions made solely from app content, interruptions outside our control, or loss of local data where you have not kept your own backup.
