No advertising or developer analytics
Version 1.1.0 contains no advertisements, AdMob SDK, advertising tracking or developer analytics service. We do not collect data from the app or transmit your listening history, favorites or ambience settings to a developer-operated server.
Local music and settings
Music and ambience recordings are included in the app. Favorites and preferences stay on your device and are not synchronized to an app account. No app registration or login is required. Playback may create temporary local audio files. Deleting the app removes ordinary local preferences, subject to device backup and restore settings.
Complimentary access and subscriptions
The app provides three days (72 hours) of complimentary full access, without ads. This period does not automatically convert into a paid subscription. After expiry, a monthly subscription is required to continue accessing the content. On iOS, Apple StoreKit verifies app and subscription transactions on the device. Production access uses the Apple-verified original download date, so reinstalling with the same Apple Account does not restart complimentary access. Minimal access-verification and timing records may be retained in the device Keychain and may survive app removal. These records are not sent to our server.
Apple processes payments and account information under its own privacy policy. We do not receive your card number. The app uses verified transaction status to grant access and restore purchases. The monthly subscription renews automatically until canceled; manage or cancel it in Apple Account subscription settings. Initial verification, purchases and restores may require internet. Bundled audio plays offline while access is valid.
Android and Google Play
On Android, Google Play Billing handles subscriptions and purchase restoration. Google processes Google Account, payment, purchase and related billing information under its own privacy practices. The app receives purchase status and verifies purchase signatures to grant access. We do not receive your payment card details and do not operate an app account or purchase-verification server.
The Android complimentary period starts at the first verified launch of an installation from Google Play and lasts 72 hours. Timing and verification records are stored in local app preferences; the app does not read your Google Account identity. This Android period is not verified against an account-wide original purchase date, and the iOS reinstall protection described above does not apply to Android. Removing or clearing Android app data can remove local timing and favorites records. Android app backup is disabled. Complimentary access requires no payment and does not automatically become a subscription.
Manage or cancel Android subscriptions through Google Play. Purchases and restoring access may require an internet connection. Bundled audio is stored locally. For Google services, see the Google Privacy Policy.
Permissions and families
The app is intended for a parent or caregiver to operate. It does not ask children for personal information and does not require camera, microphone, contacts or precise location permissions. There are no public profiles, messaging or user-uploaded content.
Apple services
Apple may process App Store, purchase and optional device diagnostic information under your Apple settings and its own privacy policy. See Apple Privacy Policy. The app does not include a separate third-party crash or analytics reporting service.
Support and this website
If you email support, we receive the email address, message and attachments you choose to send and use them to answer your request. Do not send passwords, payment card details or sensitive information about a child. Support messages are retained only as needed to resolve requests and meet applicable obligations. Visiting this website may involve hosting access logs and necessary website cookies; these are separate from the mobile app.
Your choices and rights
Remove favorites in the app or delete ordinary local app data by removing the app. On iOS, Keychain access records may remain to prevent a new complimentary period on reinstall. For requests concerning support messages or other information you have supplied to us, contact support@lullabybutton.com. Depending on your location, you may have rights to access, correct or delete information we hold. Apple account and payment data are managed through Apple; Google Play account and payment data are managed through Google.
We may update this policy when practices change. This revision describes version 1.1.0; earlier advertising-enabled versions used different practices.
