Attune

Privacy Policy

Last updated July 2, 2026 · published by Aethel Apps

Attune is a sound instrument. This policy is short because the app's design is simple: your data stays on your device.

No accounts, no collection

Attune requires no registration and collects no personal information. There is no sign-up, no user database, and no analytics tracking. We do not know who you are, and the app is built so we never need to.

What stays on your device

Your favorites, recent sounds, saved Mixer blends, streak, volume preference, and 7 Nights progress are stored locally on your device only.
All sound is synthesized in real time on your device — nothing is streamed, and no record of what you listen to leaves your phone.
Clearing the app's data or uninstalling removes everything permanently.

The only network requests

Attune contacts a server in exactly one situation: verifying a Premium subscription purchase. When you subscribe or restore purchases, a purchase token issued by Google Play is sent to our verification server, which confirms it with Google and returns the result. No other network requests are made by the app.

Payments

Subscriptions are processed entirely by Google Play. We never see or store your payment details. You can manage or cancel your subscription anytime in the Play Store's subscription settings.

Wellness disclaimer

Attune is designed for relaxation, focus, and enjoyment of sound. It is not a medical device, and its frequencies, tones, and programs make no treatment claims. Binaural states require stereo headphones. If you have a medical condition, including epilepsy or hearing sensitivity, consult a professional before extended listening sessions.

Children

Attune is intended for users aged 13 and older. Because the app collects no personal information from anyone, it collects none from children.

Changes

Any updates to this policy will appear on this page with a revised date.
