Andrade & Feistel Technologies ("we", "us", or "our") developed the Sweet Dreams mobile application (the "App") as a free, ad-supported app. This page is used to inform visitors about our policies regarding the collection, use, and disclosure of Personal Information for anyone who decides to use our App.
By using our App, you agree to the collection and use of information in accordance with this policy.
Summary: Sweet Dreams does not collect any personal data and does not share any data with third parties.
Sweet Dreams is a relaxation app that plays music and ambient sounds (such as Bach, Chopin, Mozart, rain, fan, and white noise) to help children fall asleep. The App does not require you to create an account and does not collect, store, or transmit any personally identifiable information, such as your name, email address, location, or device identifiers.
Any settings you choose within the App, such as selected sounds, volume, or sleep timer duration, are stored locally on your device and are never sent to us or to any third party.
We do not share any data with third parties. No information related to your use of the App is sold, rented, or shared with advertisers, analytics providers, or any other outside party.
Sweet Dreams contains ads. These ads are displayed without collecting or sharing any personal data or device identifiers. No ad personalization based on user data takes place within this App.
Sweet Dreams is designed to continue playing audio while you use other apps or even when your phone screen is off, so that the sound can help a child sleep throughout the night. This functionality operates entirely on your device and does not involve sending any data to us or to third parties.
Sweet Dreams is intended for use by parents and caregivers to help children sleep, and is rated for all ages (3+). We do not knowingly collect any personal information from children or from any user of the App. The App has been designed to operate without collecting or processing any user data, in line with applicable children's privacy regulations (including COPPA in the United States and similar regulations in other jurisdictions).
If you are a parent or guardian and have any concerns about this App, please contact us using the information below.
Since the App does not collect or transmit personal data, there is no personal information at risk of exposure through our systems. We nonetheless strive to follow industry best practices in app development to keep the App safe and reliable.
Because Sweet Dreams does not collect or store any personal data on our servers, there is no user data held by us that would need to be deleted. Any local data (such as your sound or timer preferences) can be cleared at any time by clearing the App's data or cache through your device settings, or by uninstalling the App.
This App may contain links to other sites, such as our developer website. If you click on a third-party link, you will be directed to that site. Note that these external sites are not operated by us, and we recommend reviewing the Privacy Policy of any third-party site you visit.
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. This policy is effective as of the date stated at the top of this page.
If you have any questions or suggestions about our Privacy Policy, do not hesitate to contact us:
