Cosmo Apps ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard information when you use our mobile applications, including White Noise and any future apps published under the Cosmo Apps brand.
We collect minimal, non-personal data such as crash reports and anonymized usage analytics to improve app stability and performance. We do not collect personally identifiable information unless you voluntarily provide it — for example, when contacting our support team via email.
Any data we collect is used solely to diagnose and fix technical issues, improve app functionality, and enhance the overall user experience. We do not use your data for advertising, marketing, or profiling purposes.
We do not sell, rent, or trade your personal information to third parties. We may share anonymized, aggregated data with analytics services (such as Firebase Analytics) to understand usage patterns and improve our apps.
We implement industry-standard security measures to protect any information we process. All sound preferences and settings are stored locally on your device. While no electronic transmission method is 100% secure, we take commercially reasonable steps to safeguard your data.
Our apps may integrate third-party services for analytics or crash reporting. These services operate under their own privacy policies, and we encourage you to review them. We carefully select partners who share our commitment to user privacy.
Our apps are not directed at children under the age of 13. We do not knowingly collect personal information from children. If you believe we have inadvertently collected such data, please contact us and we will promptly delete it.
You may request access to, correction of, or deletion of any personal data we hold about you at any time by contacting us. We will respond to your request within 30 days.
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated revision date. Continued use of our apps after modifications constitutes acceptance of the updated policy.
If you have questions or concerns about this Privacy Policy, please reach out at cosmoapps13@gmail.com.
